The central concept is general purpose financial assistance as it appears in subsection 9(1) of the Federal Financial Relations Act 2009. Under that Act, the Treasurer may determine that a specified amount is to be paid to a State as a grant of general purpose financial assistance. These grants are unconditional in the sense that the Act does not tie them to specific projects or programs, unlike specific purpose payments (tied grants). The term "State" likely includes both the six States and the two self-governing Territories, as the table includes the Australian Capital Territory and the Northern Territory. The concept of "determination" refers to the Treasurer's power to unilaterally set the amount and timing, subject only to the limits in the Act and any intergovernmental agreements. Another key concept is payment on a specified date - here 21 July 2017. The instrument does not say what happens if that date passes before payment is made; presumably the obligation survives but the instrument does not create a statutory cause of action for late payment. The amounts themselves are precise to the cent, implying they are derived from a formula or calculation external to the instrument - likely the horizontal fiscal equalisation (HFE) methodology administered by the Commonwealth Grants Commission. The zero amounts for six jurisdictions indicate that this determination does not cover the main annual GST distribution, but is a supplementary or special payment. The commencement concept is also important: the instrument commenced on the day it was made, rather than on a later date or retrospectively. That means the Commonwealth could legally make the payment on 21 July 2017 (three days after the determination was signed) because the determination was already in force by that date. The concept of a determination series (No. 100) suggests that the Treasurer issues numbered determinations each month or each quarter. Finally, the concept of general purpose distinguishes this from other financial assistance that is tied to specific purposes: the States are free to spend these funds on any state purpose without restriction from the Commonwealth, subject only to the Constitution and their own legislation.

The primary affected entity is the Commonwealth of Australia, which is legally obligated to make the payments specified in the table. The Department of the Treasury and the Department of Finance would be responsible for arranging the transfer. The determination creates a legal duty on the Commonwealth, enforceable (at least in principle) through administrative law mechanisms if the payment is not made. The immediate beneficiaries are the States and Territories listed, but only two actually receive funds: Western Australia and the Australian Capital Territory. For Western Australia, $62.86 million is a substantial transfer - though relative to its total state budget it is modest. For the ACT, $3.3 million is also significant but again small in relative terms. The other six jurisdictions (NSW, Vic, Qld, SA, Tas, NT) are affected only in that they receive nothing. That zero amount might reflect a negative adjustment or a reconciliation where they have already received their full entitlement under a previous determination. The effect on each State's budget is direct: each recipient can add that amount to its general revenue, to be spent on whatever state priorities it chooses. The determination also affects state taxpayers indirectly: the recipients have more money to spend without raising additional state taxes; conversely, Commonwealth taxpayers fund the payment. Businesses and individuals in the recipient States may benefit from any additional spending, but because the funds are untied, the economic effect depends on the State's spending decisions. The determination also affects other stakeholders in fiscal federalism: the Commonwealth Grants Commission’s work underpins the amounts; state treasuries monitor these determinations; and the public (via budget papers) sees the aggregate transfers. The determination does not affect private individuals directly - there is no obligation on any person except the Commonwealth. However, any failure by the Commonwealth to pay could be challenged by the affected States. In that sense, it creates a right in the States to enforce payment. Because the determination is a legislative instrument, it also affects Parliament: either House could potentially disallow it, though compliance with the Legislation Act 2003 would need to be checked. In practice, such determinations are rarely disallowed as they are routine fiscal machinery.

The instrument imposes one clear duty: the Commonwealth must pay the amounts listed in the table to the respective States. This duty arises directly from clause 3 read with the table. The duty is owed to each State or Territory that is listed as a recipient. The duty is not conditional on any action by the State (other than perhaps maintaining a bank account to receive the funds). The duty is time-specific: payment is to be made on 21 July 2017. The instrument does not state what happens if the Commonwealth fails to pay on that date - whether interest accrues or whether the obligation simply continues. The States have a corresponding right to receive the specified amounts. That right may be enforceable in the courts, at least as a statutory right, but the source does not specify any enforcement mechanism. There is also a right of the States to use the funds for any purpose, because the grant is for "general purpose financial assistance". The instrument does not impose any reporting, acquittal, or accountability duties on the States. The States do not have to apply for the payment or justify it. There is no duty on the Commonwealth to make further payments beyond this determination; each subsequent period requires a new determination. The Treasurer’s power to make such a determination is itself a duty? No - it is a discretionary power under s9(1) of the Act. The instrument records the exercise of that discretion. If the Treasurer had not made this determination, no payment would have been due. So the duty to pay is not ongoing; it is episodically created by determination. No other duties or rights arise under this instrument for private persons. For example, no third party can demand payment; the States are the only intended beneficiaries. The instrument does not create any private right of action. If a State failed to receive the money, it could theoretically bring a claim for debt or statutory obligation, but given the typical Crown immunity complexities, the State would likely need to rely on the Act for a cause of action rather than this determination alone. For non-recipient States, there is no duty or right at all - they simply are not named as recipients. Their zero entry confirms that no amount is owed. This highlights that the determination is an exclusionary tool: it specifies which States get money and which do not, but it does not create a duty to explain why some get zero.

The determination itself contains no penalty provisions. It does not create any offence, civil penalty, or infringement notice. The only conceivable "penalty" for non-compliance by the Commonwealth would be a court order compelling payment or an award of damages, but the instrument does not specify that. Enforcement would rely on general principles of statutory duty. If the Commonwealth failed to pay on the specified date, a State could seek judicial review under the Administrative Decisions (Judicial Review) Act 1977 (ADJR Act), arguing that the failure to pay is a breach of a duty imposed by the instrument, or that the Commonwealth had no power to withhold payment once the determination was made. However, the ADJR Act may not apply to such a decision (it is the making of the determination itself that is reviewable, not a subsequent failure to implement it). Alternatively, a State might seek a declaration or an order for mandamus requiring the Commonwealth to pay. But the instrument is silent on interest, penalties for late payment, or set-off. The absence of penalties is notable: even a private contract for payment of $66 million would typically include interest on late payment. The lack of such provisions suggests that the Commonwealth’s obligation is expected to be honoured as a matter of routine, and that any dispute would be resolved politically rather than through legal enforcement. The source does not mention any enforcement mechanism beyond the determination itself. For a State that receives zero, there is no penalty for not receiving money - it simply does not get paid. The determination does not penalise a State for overpayment or misapplication of funds; those matters would be dealt with under other laws (e.g., the Criminal Code Act 1995 for fraud if a State claimed money it was not entitled to, but here the instrument itself sets the amount). In short, the enforcement regime for this instrument is skeletal: the duty is stated, but the consequences of breach are left to the general law. This is common for appropriations-like instruments where the executive is expected to comply as a matter of course. The lack of a penalty clause does not mean the obligation is unenforceable; it means the remedy is discretionary.

This determination is made under subsection 9(1) of the Federal Financial Relations Act 2009 (the Act). That Act is the primary source of the Treasurer’s power. The determination must be read subject to the Act’s provisions, including any limits on amounts, conditions on grants, or requirements for consulting states. The Act itself is likely part of a broader framework including the Federal Financial Relations Act 2009 and the Intergovernmental Agreement on Federal Financial Relations which sets out the agreed distribution methodology. The amounts in the determination almost certainly derive from the GST distribution formula under the A New Tax System (Commonwealth-State Financial Relations) Act 1999 and related legislation. That Act provides for the distribution of GST revenue to states, but this determination is for general purpose financial assistance outside the GST pool. The determination also interacts with the Constitution, section 96, which allows the Commonwealth to grant financial assistance to any State on such terms as it sees fit. This determination is a classic section 96 grant, though it imposes no terms. It also interacts with the Legislation Act 2003 regarding registration on the Federal Register of Legislation, disallowance, and sunsetting. If not exempt, it would be subject to disallowance within 15 sitting days after tabling. The Public Governance, Performance and Accountability Act 2013 (PGPA Act) governs the financial management of Commonwealth money; the determination would trigger a payment that must be authorised by a proper appropriation. The payment would likely be debited from the Consolidated Revenue Fund under an appropriation in the Act or an annual Appropriation Act. The determination itself does not create an appropriation; it merely authorises the executive to pay. The payment must be consistent with the Financial Management and Accountability Act 1997 (now superseded) or PGPA Act. There is also interaction with state legislation: once received, the funds become part of the state’s consolidated revenue, subject to each state’s own appropriation and financial management laws. The determination does not affect Commonwealth-state tax arrangements, but it interacts with the overall fiscal equalisation landscape. For Western Australia, this payment may be part of transitional or special arrangements outside the normal equalisation formula. Finally, the determination interacts with other determinations in the series; cumulative payments across determinations must not exceed any statutory limit in the Act, if any. The source does not mention any such limit, but the Act might have an overall cap.

The source contains no amendment history. This is a standalone determination that has not been amended. The determination itself is a single instrument; there is no indication that it was repealed or replaced. Because it is a legislative instrument, it could theoretically be amended by a later determination (e.g., Determination No. 100A) but none is shown. The determination states its name as "No.100 (July 2017)", suggesting it is one of a numbered series. The series likely continues with later months and years, each superseding prior determinations for future payments, but not amending prior ones. If there were any amendments to the Act (the parent legislation) after 18 July 2017, they could affect the validity of future determinations but not this one, which is already made. The determination itself has no sunset clause; it remains in force until repealed or spent. It is arguably spent after 21 July 2017, as the payment may have been made, but it still has legal effect as a record of an obligation. Under the Legislation Act 2003, legislative instruments are subject to automatic repeal after 10 years unless exempted. This determination would likely be repealed by the Federal Register when it is superseded or if it has no ongoing operation. There is no amendment history because the instrument is simple and final. There are no amending instruments cited. The source does not mention any explanatory statement, but one would have been lodged when the determination was registered. The lack of amendment history is typical for a routine monthly determination: each month’s instrument is new, not an amendment of the previous one. For a deep dive, it is worth noting that if one wanted to track changes in allocation, one would need to examine each successive determination, not rely on an amended version of No.100. The instrument’s longevity is unclear; it may have been repealed administratively after payment. The absence of amendment history is itself an important piece of information: it signals that the instrument is not part of an evolving text but is a one-off directive.

The source does not mention any litigation relating to this determination. There is no recorded court case, challenge, or judicial consideration cited. This absence is consistent with the nature of the instrument: it is a routine fiscal transfer that rarely provokes legal dispute. The amounts are small relative to state budgets, and the distribution is likely uncontroversial (Western Australia received additional funds under a special arrangement; ACT received a small amount; other states got nothing but presumably they had already received their full share through other determinations). If there were a challenge, it might arise from a state arguing that the determination was ultra vires the Act because it breached an intergovernmental agreement or because the Treasurer’s discretion was exercised improperly. Alternatively, a state that received zero might argue that the determination failed to give effect to a statutory entitlement (if such an entitlement exists). But the source does not indicate any such litigation. The absence of litigation history can be significant: it suggests the determination was accepted by all parties and that the framework is working as intended. It also means there is no judicial interpretation of clause 3 or the table to guide future application. For practical purposes, practitioners can assume the determination is valid and effective. However, if one were to research the broader litigation history of the Federal Financial Relations Act 2009, there might be cases concerning the meaning of "general purpose financial assistance" or the Treasurer’s power. But those cases are not about this specific determination. The source does not name any case. Therefore, under the rule to ground claims in the source, the only statement that can be made is that this specific instrument has no recorded litigation history in the source provided. One could hypothesise about potential grounds for judicial review (e.g., failure to consider relevant considerations, acting for an improper purpose) but that would be speculation not grounded in the source. The deep dive must be rigorous: it is better to state the absence plainly rather than invent possibilities. If a reader needs to know whether this determination was challenged, the answer from the source is: no information is given. The instrument itself contains no reference to any legal challenges.

Several aspects of this determination could catch an unwary reader. First, it is not an Act; it is a legislative instrument made by the Treasurer alone. This means it is not subject to the full parliamentary scrutiny of a bill, though it is subject to disallowance. One cannot cite it as if it were primary legislation; its legal weight derives from the Act. Second, the zero amounts for six jurisdictions are ambiguous. They do not mean those jurisdictions have no entitlement; they may have already received their full year's allocation through earlier determinations, and this determination merely top-ups two specific jurisdictions. Relying on this determination alone to calculate total assistance to a state would be misleading. Third, the precise amount ($66,152,613.61 total) with cents suggests a calculation based on a formula, but the formula is not stated. The reader cannot verify the calculation from the source. The numbers may be tied to a historical month or a special adjustment. Fourth, the date - payment on 21 July 2017 - is specified. If the payment was not made on that day, the Commonwealth may have breached a statutory duty, but the instrument does not provide a remedy. The absence of a late-payment penalty is a gotcha for anyone assuming standard commercial terms apply. Fifth, the series number "No.100" might cause someone to assume it is the 100th determination in the series; but there may be gaps or multiple streams. One cannot assume it is part of a continuous numeric sequence without checking the register. Sixth, the commencement on the day it is made (18 July 2017) means it was legally operative before the payment date. But if the Treasurer signed it after 21 July, the payment date would be in the past, creating an issue of backdating. Here, the dates line up. Seventh, the determination does not contain a sunset clause. Under the Legislation Act 2003, legislative instruments are repealed automatically after 10 years unless exempted. This determination would have been repealed on 18 July 2027 if not earlier. A reader who assumes it is still in force after that date would be wrong. Eighth, the determination does not refer to the source of appropriation - the money must come from the Consolidated Revenue Fund under an appropriation. The determination itself does not create an appropriation; it merely authorises a payment. If the appropriation had lapsed, the payment would be unlawful. Ninth, there is no definition of "State" in the instrument; the Act would define it. But the table includes the ACT and NT, which are territories, not states. The Act may have a broad definition. Tenth, the determination is silent on conditions; a state might assume no strings are attached, but the Act itself might impose general conditions on general purpose financial assistance (e.g., proper use of funds, auditing). One must read the Act to be sure. The final gotcha: the instrument is remarkably short; many users might think it is incomplete or that there are missing schedules. It is not - it is exactly as published.

For the Commonwealth (the Department of the Treasury, Department of Finance, and the Reserve Bank if involved), compliance requires arranging the transfer of exactly $66,152,613.61 from the Consolidated Revenue Fund to the Western Australian and ACT Treasuries by 21 July 2017. The payments must be made to the correct state accounts. The Commonwealth should also ensure that this determination is registered on the Federal Register of Legislation, tabled in Parliament, and that any disallowance period expires without action. For the Western Australian Government and the ACT Government, compliance is minimal: they must accept the payment and credit it to their consolidated revenue. They may need to record it in their financial statements and report it as general revenue. No specific acquittal is required by this determination. However, states must comply with their own financial management laws and any conditions in the Act (the source does not mention conditions, but the Act might). For states that received zero, there is no compliance action needed; they simply note no payment was due. For the Treasurer, compliance means ensuring that the determination is within power under s9(1) of the Act, that the amount does not exceed any statutory limit, and that the payment is consistent with the Intergovernmental Agreement. For Parliament, compliance may involve scrutinising the instrument and potentially disallowing it if a member objects. For auditors (ANAO), compliance with this determination means verifying that the payment made matches the amounts and date in the table. For private practitioners advising a state, compliance means confirming that the state received the correct amount on time and that the state’s use of the funds is unrestricted. If a state wishes to dispute a zero amount, it would need to look at the Act and the reasons for zero, which are not in this instrument. Overall, compliance is straightforward because the instrument is very simple. The main risk is a clerical error in payment. The instrument does not prescribe any reporting, so the states need not file a return. The only ongoing compliance issue is ensuring that the payment is not misused if the Act imposes conditions, but the source does not indicate any. For record-keeping, the determination itself should be retained in the state’s archives as evidence of entitlement. For the Commonwealth, the determination provides authority to pay; without it, a payment of this exact amount might be unauthorised. Therefore, the Commonwealth ensures the determination is not repealed before payment. After payment, the determination can be stored as a historical record.
