Conversely, if section 5 is necessary to do the operative work, section 4 adds nothing.

(ss 3(2), 4)\n- Where an existing Commonwealth or Territory law provided for the death penalty, that reference is to be read as if it instead provided for imprisonment for life. This means courts and sentencing authorities must treat death sentences under those laws as life imprisonment. (s 5)\n- The Act separately provides that the death penalty must not be imposed in relation to offences under State law (s 6), so the ban on imposing death sentences operates in relation to State offences as well. (s 3(3), s 6)\n- The Act applies both inside and outside Australia, extends to all Territories, and applies to offences committed before, on or after the day it commences. (ss 3(1), 3(4))\n- The Act comes into force on the day it receives Royal Assent. (s 2)\n\n# Who is affected and who decides\n\n- Courts and sentencing authorities: must no longer impose the penalty of death for offences covered by the Act and must instead apply imprisonment for life where the law previously specified death. (ss 4, 5, 6)\n- Commonwealth and Territory legislative schemes: any statutory references to the death penalty are to be read as if they referred to life imprisonment. (s 5)\n- State laws: the Act expressly prohibits imposition of the death penalty in relation to State offences (s 6), so State courts must not impose death as a penalty for those offences. (s 3(3), s 6)\n- The administering governments (Commonwealth, Territories and States) carry the practical obligations that flow from substituting life imprisonment for death (see \"Practical implications\" below). (s 5)\n\n# Why this matters (stated effect and implied operational consequences)\n\n- Stated textual effect: the Act removes death as a sentencing option for covered offences and substitutes life imprisonment where a statute previously provided death. (ss 4, 5, 6)\n\n- Practical implications apparent from the text:\n  - Sentencing change: courts lose the option to impose death and must sentence to life imprisonment where death was previously prescribed. This alters the available legal penalties for covered offences. (ss 4, 5, 6)\n  - Temporal reach: the change applies to offences committed before, on or after commencement, so the Act affects past offences as well as future ones. (s 3(4))\n  - Geographic reach: the ban is written to operate inside and outside Australia, for Territories, and in relation to Imperial Acts to the extent Parliament can. (s 3(1)–(2))\n\n# Costs, incentives, trade-offs and implementation issues (mechanisms, not judgments)\n\n- Cost bearer: the substitution of imprisonment for life for offences that would previously have attracted death implies additional or continuing custodial costs borne by the relevant government (Commonwealth, Territories or States) because those persons will be imprisoned for life rather than executed. The Act itself creates the substitution; it does not allocate specific funding. (s 5)\n\n- Behavioural effect on decision‑makers: legislators and courts no longer can use death as a statutory or sentencing option for covered offences; legislatures that previously relied on death for deterrent or retributive purposes would need to rely on other penalties instead. The Act removes a sentencing choice (ss 4, 5, 6).\n\n- Compliance and administrative burden: correcting legislative drafting, sentencing practice, prison administration, parole and corrections policy, and criminal legal advice to reflect that death is no longer an available penalty are foreseeable operational tasks following the change the Act mandates. The text substitutes penalties by operation of law but does not prescribe administrative steps. (s 5)\n\n- Legal interpretation points that may require adjudication: the provision that references to the punishment of death are to be \"read, construed and applied\" as if life imprisonment were substituted (s 5) may give rise to questions about how existing statutory frameworks, ancillary provisions (for example, those dealing with parole, remission, or special sentencing procedures), and pre-existing orders are to be treated in detail. The Act does not itself supply those interpretative details.\n\n- Interaction across jurisdictions: the Act directly addresses Commonwealth and Territory laws and uses s 6 to prohibit imposition in relation to State laws (ss 3(2)–(3), 6). That cross-jurisdictional structure creates an intergovernmental interface: the text removes the sentence option nationally as to imposition, but practical administration of substituted sentences (prison management, parole systems, etc.) remains a matter for the relevant governments.\n\n# Concrete provisions to watch (by section)\n\n- s 3(1)–(4): Scope — extraterritorial application, Territories, Imperial Acts to extent Parliament permits, and temporal application to past offences.\n- s 4: Express abolition of liability to death for offences within the s 3(2) scope.\n- s 5: Automatic textual substitution of \"imprisonment for life\" where statutes previously provided death.\n- s 6 and s 3(3): Prohibition on imposing death in relation to State law offences.\n\n# Limits of what the text says\n\n- The Act contains no statement of policy rationale or budgetary measures; it effects legal change through substitution and prohibition but leaves the practical administration, funding and detailed interpretative answers to other laws, courts or administrative action.

The law rewrites itself without needing Parliament to go through every old statute.\n- **States included (partially)**: Courts in the States are also prohibited from *imposing* a death sentence — even if an old State law technically still said they could.\n- **Applies to past crimes too**: Even if someone committed an offence before 1973, they cannot be executed for it.\n- **Applies everywhere**: The law covers acts committed inside and outside Australia, and in all Territories (like the ACT and NT).\n\n### Who does this affect?\n\nEssentially **every person in Australia** and anyone subject to Australian law. It means no Australian government — federal, territory, or state — can lawfully execute a person, regardless of the crime committed.\n\n### Why does it matter?\n\nBefore this Act, the death penalty was technically still on the books for some offences (including treason and piracy).
