The regulations establish several organising legal concepts that determine entitlement, calculation, and administrative operation.
Prescribed classes and prescribed cards. Regulation 3(1) defines what is meant by a prescribed card and lists specific Commonwealth concession cards: Pensioner Concession Card; Low Income Health Care Card; various repatriation health cards (TPI Gold, War Widows Gold, Gold Repatriation Health Card (EDA), Gold Repatriation Health Card for 80 or more impairment points under the Military Rehabilitation and Compensation Act 2004). Regulation 6 then prescribes classes of eligible person, which include holders of prescribed cards and holders of a Commonwealth Seniors Health Card (r 6(a)-(b)).
Prescribed payments. Regulation 3(1) defines prescribed payments to include specified payments under the Commonwealth Social Security Act 1991 (Austudy, JobSeeker, parenting payment, special benefit, youth allowance as listed) and other Commonwealth programs or payments (Abstudy, payments under Community Development Employment Project or Remote Jobs and Economic Development Program, Self-Employment Assistance allowance, certain war widow pensions from UK or New Zealand, and farm household allowance under the Farm Household Support Act 2014). These payments create a financial eligibility route separate from card-holding.
Eligibility by occupancy capacity. The notion of occupying land as a principal place of residence in a prescribed capacity is critical. Regulation 3(2) provides a detailed list of tenures and relationships that qualify a person as occupying their principal place of residence in a prescribed capacity. That list covers legal ownership, Crown tenures, purchaser arrangements with staggered payments, life-occupancy arrangements where no rent is payable, co-ownership structures, long leases or licences, approved aged persons housing, spouses and domestic partners of qualifying occupants, and beneficiaries under estates.
Indexation mechanism. Regulation 3(3) prescribes that any monetary amount followed by the word "indexed" will be adjusted annually on 1 July by a multiplier equal to the CPI for the December quarter of the immediately preceding year divided by the CPI for the December quarter of 2023, with rounding up to the nearest 10 cents. Regulation 3(4) imposes a floor preventing the indexed amount for a financial year from being less than the amount remitted or paid in the immediately preceding financial year.
Single-payment-per-premises rule. Regulation 7(1)(c) requires, subject to several exceptions, that no other eligible person be given a payment under s 3(2) of the Act for that financial year in respect of the same residential premises. The regulation provides limited carve-outs: it does not apply to certain classes (residents in rooming houses or supported residential facilities where the other person would be in the same room to block duplicate payments, r 7(3)), it allows ministerial splitting where the Minister decides it is appropriate (r 7(3aa)), and it contains the administrative requirement of an application by 31 December (r 7(1)(a)).
Water-rates remission architecture. Regulation 5 creates an entitlement to a remission of water rates for land for ratepayers who meet either prescribed-card-or-prescribed-payments and prescribed-capacity occupancy tests on the relevant date, or who satisfy a Ministerial means-test of exceptional hardship at the time of recovery of the rates (r 5(1)(a)-(c)). It then specifies that the remission is 30 per cent of the rates payable for the financial year, subject to a prescribed minimum and maximum remission for that year (r 5(4)). The regulations define "relevant date" to be either the billing date or the date on which the rates are payable (r 5(5)). There is also a requirement that if a ratepayer meets the conditions on the payable date but not on the billing date, they must have been entitled to a remission in the preceding rating period to qualify (r 5(2)).
Switch for Solar exclusion. Regulation 7(3a) disqualifies a person who enters the State Switch for Solar program in the relevant financial year from receiving a concession payment under s 3(2) for that year and then applies a multi-year exclusion (9 or 10 years) depending on circumstances, with a ministerial exception available if the Minister is satisfied that exceptional circumstances exist (r 7(3a)-(3c)). If a person has already received a payment for that financial year, r 7(3b) protects them from being required to return it.
Dynamic ministerial instruments. Several material eligibility parameters are delegated to the Minister via notices published on the concessions website. These include the amounts determining who is a low income earner and any revisions during the financial year (r 3(1) definition of low income earner), and the form and manner of applications and the ADI account detail requirement (r 7(1)(a)-(b)). The Minister also has discretion to determine means tests when assessing hardship for water-rate remissions (r 5(1)(c)) and to split payments among co-residents (r 7(3aa)).
Interplay with Commonwealth and other South Australian statutes. The regulations incorporate terms and eligibility criteria that depend on other statutes. Examples include references to Commonwealth Social Security Act 1991 payments, Migration Act 1958 and Migration Regulations 1994 (bridging visa E) for relevant asylum seekers (r 3(1)), Family Relationships Act 1975 for the definition of domestic partner, and various state Acts for tenure concepts such as Supported Residential Facilities Act 1992, Residential Parks Act 2007, and Residential Tenancies Act 1995. Water rates are defined in relation to the Irrigation Act 2009 and Renmark Irrigation Trust Act 2009 (r 3(1) definition of water rates).
In sum, the main concepts are eligibility classes, prescribed occupancy capacities, indexation rules, the water-rates remission formula and conditions, administrative application rules and Ministerial discretions, and the Switch for Solar multi-year disqualification. Each of these determines the flow of payments and remissions and sets the points at which administrative discretion or dynamic Ministerial instruments can alter on-the-ground entitlements.
