Extradition from Australia: How the Procedure Works and What an Extradition Lawyer Does

Section 47B normally requires arresting police to state the substance of the reason for arrest, subject to exceptions. Identify the warrant, foreign state, date of arrest, any section 16 notice and whether custody is extradition, immigration or interstate custody. For detailed objections see the separate guide to stopping extradition from Australia. Detailed refusal grounds and litigation

Which law applies: an extradition country, New Zealand, or an Australian state?

Part II of the Act applies to a requesting country other than New Zealand that falls within the statutory definition of an “extradition country.” Under section 5 and the relevant regulations, that status must be checked for the particular foreign state. The existence of diplomatic relations, an INTERPOL notice or a bilateral treaty is not itself enough to show that an individual request satisfies Australian domestic law. Section 11 permits country-specific regulatory modifications reflecting bilateral or multilateral treaty arrangements. A lawyer should therefore inspect both the current Act and the specific regulations and applicable treaty terms, rather than relying on a generic country list.

New Zealand requests use a deliberately different, police-and-prosecution-administered “backing of warrants” mechanism under Part III. Transfers between Australian states and territories are governed instead by the Service and Execution of Process Act 1992 (Cth). Neither process should be confused with Part II international extradition. Australia is not an EU Member State: a European Arrest Warrant does not operate as an Australian surrender order. Likewise, deportation for immigration reasons is legally distinct from extradition requested for criminal prosecution or punishment.

Section 5 normally requires an offence punishable in the requesting country by a maximum of at least 12 months’ deprivation of liberty, with treaty alternatives. Section 6 covers an arrest warrant, an unsentenced conviction or unserved punishment. Section 10(1) addresses convictions in absentia separately.

Who handles arrest and the hearing, and who makes the final decision?

An application for a Part II extradition arrest warrant goes to a magistrate or an eligible Judge under section 12. The latter means a judge of the Federal Circuit and Family Court of Australia (Division 2) who has consented and been nominated under section 45A; not every federal judge has this function. Importantly, section 45B states that magistrates and eligible judges exercise their extradition functions in a personal capacity, not as a court. This is why the initial eligibility hearing should not be casually described as a trial before the Federal Court or the state Supreme Court.

Section 15(1) requires appearance as soon as practicable in the state or territory of arrest; section 15(4) permits a controlled transfer between Australian jurisdictions. Either party may initiate section 19 proceedings after reasonable preparation. The Attorney-General’s Department administers ordinary requests, not foreign guilt.

A section 19 eligibility decision is not authority to surrender. Once section 21 review is unavailable or finished, the Attorney-General separately determines surrender under section 22. An Australian extradition hearing does not try the foreign offence.

From provisional warrant to surrender: the stages and the useful clock

The 45-day rule is frequently misunderstood. Under section 17(2), a person still on section 15 remand after 45 days from the day of arrest must be brought before a magistrate or eligible judge if the formal request has not been received; if it has been received but no section 16 notice is issued within five days after that period, the statutory review is likewise engaged. Section 17(2A) ordinarily requires release, but allows narrowly described findings concerning exceptional circumstances and reasonably anticipated receipt of a request or notice. Section 11 regulations may change the 45-day period for particular countries. A pending waiver under section 15A also changes the calculation. Therefore neither “automatic release on day 45” nor “everyone can be detained for only 45 days” states the law correctly. The exceptional-circumstances condition in section 17(2A)(a) applies to a missing request; when a request has arrived but the section 16 notice is outstanding, section 17(2A)(b) instead turns on the expected timing of the Attorney-General's notice decision.

Section 21 also imposes separate 15-day limits after the Federal Court order for appeal to the Full Federal Court and after the Full Federal Court order for an application for High Court special leave (sections 21(4)–(5)). Section 21(6)(d) ordinarily confines review to the material before the original decision-maker, subject to the specific exceptions in section 21A; it is not a fresh trial of guilt.

There is no overall 45-day maximum for subsequent custody, section 19 hearings, section 21 litigation or ministerial determination. Record actual dates and applicable remand orders.

Can a person obtain bail while extradition is pending?

Section 15(6) forbids release on bail at the initial Part II remand unless special circumstances justify it. The same special-circumstances threshold appears after a positive eligibility finding under section 19(9A), and in identified review situations under section 21. Ordinary assumptions about bail for domestic criminal charges cannot be transferred to an extradition case. A rejected section 15 bail application cannot simply be repeated during the same remand: section 15(3) requires evidence of a change of circumstances that might justify bail.

Collect proof of residence, identity, family ties, medical needs and workable bail conditions; none alone guarantees bail. Section 49B governs conditions. Section 49C imposes a separate special-circumstances bail test during judicial review of executive surrender, unlike section 21 eligibility review. A section 15A waiver has its own custody consequences.

What does the Australian decision-maker test at the section 19 hearing?

The hearing is not a trial of the foreign criminal case. Section 19(2) requires, among other things, appropriate supporting documents, compliance with the relevant offence and dual-criminality criteria, and the absence of an established statutory extradition objection. Section 19(3) describes duly authenticated arrest warrants or conviction-and-sentence records together with a description of the alleged conduct, offence and punishment. Translating and authenticating foreign documents correctly is therefore a real issue, not a formality. Section 19(4) permits a reasonable adjournment to correct minor documentary deficiencies; it is unsafe to assume every defect compels release. For dual criminality, section 19(2)(c) looks to the law of the part of Australia where the hearing is held at the time the extradition request was received—not automatically to Australian criminal law on the date of the alleged conduct.

Section 19(5) prevents evidence merely contradicting alleged foreign conduct. Vasiljkovic v Commonwealth [2006] HCA 40 upheld a no-prima-facie-case scheme and found Australian citizenship no categorical bar. Pasini v United Mexican States [2002] HCA 3 addresses the administrative nature of eligibility and the judicial nature and record limits of review under section 21.

Eligibility may concern only some counts. Reconcile section 19(9)(c) records, section 16 notice and authenticated foreign papers. Section 19(10) orders release if eligibility fails, subject to a requesting-country section 21 review. A positive order starts the 15-day review clock.

Is consent the same as waiving extradition?

No. Section 18 consent to surrender is a route after the Attorney-General's section 16 notice, allowing the person to consent to surrender for specified offences. The magistrate or eligible judge checks that the consent is voluntary and explains consequences; the Attorney-General still makes the separate section 22 surrender determination. The usual speciality framework under section 22(4), generally limiting prosecution after surrender for other pre-surrender offences, must be considered in that decision.

Section 15A is a different and potentially more consequential waiver of extradition. It can operate before a section 16 notice, or after notice but before the section 18 or 19 route has concluded. The decision-maker must check voluntariness, representation or adequate opportunity for it, and that the person understands the consequences for withdrawal and possible absence of any speciality assurance. The Attorney-General then makes a distinct determination under section 15B, with its own torture and death-penalty safeguards. Both shortcuts deserve independent advice; agreeing to move promptly is not the same as agreeing to every legal consequence. Under section 15A(5)(b), a person who has waived extradition cannot apply for the waiver order to be revoked. Section 15A(4A) requires detention until surrender or release under section 15B(4), so the person should seek individual legal advice before deciding whether to waive extradition.

What changes if the request comes from New Zealand?

Part III does not require the same section 16 notice, section 19 eligibility hearing or section 22 Attorney-General decision. Under sections 28–29, a magistrate or eligible judge may indorse a New Zealand arrest warrant for Australian execution or issue a provisional warrant. Sections 32–34 deal with remand and surrender. Section 34(2) gives the magistrate or judge a distinct power to release where surrender would be unjust, oppressive or too severe a punishment for the statutory reasons; this is not the general Part II test. If only a provisional New Zealand warrant exists, section 33 calls for release once reasonable time for an indorsed warrant has passed without one being obtained. New Zealand also has its own informed-consent route under section 33A: once an indorsed New Zealand warrant exists, voluntary consent confirmed after the required explanation leads to a surrender warrant without a section 34 hearing. That is neither section 18 consent nor section 15A waiver under Part II.

Section 35 provides review in the Federal Court, then an appeal to the Full Federal Court and a possible special-leave application to the High Court, with separate 15-day statutory time limits. Unlike the usual Part II review rule, section 35(6)(d) allows the Federal Court to receive additional or substituted evidence on its initial New Zealand rehearing. At the subsequent appeal stage, section 35(6)(e) generally limits the record to the material before that reviewing court. In Kisun v New Zealand [2025] HCADisp 8 (6 February 2025), the High Court held it had no power to extend the section 35(5) period for seeking special leave. This later decision is especially important if a relative has already received an adverse Full Federal Court order: do not assume that an ordinary court extension application will repair a missed deadline. The Commonwealth Director of Public Prosecutions also identifies an execution role in incoming New Zealand matters, unlike the ordinary central-authority route. Section 35 contains three separate clocks for an order made under section 34: Federal Court review within 15 days of the section 34 order; appeal to the Full Federal Court within 15 days after the Federal Court order; and an application for High Court special leave within 15 days after the Full Federal Court order. There is no direct section 35 High Court step from the first Federal Court order. Because section 35(1) governs section 34 orders, do not assume that its statutory review route remains available after a section 33A consent warrant. Separately, section 38(7) permits an application to the Federal Court for release if a New Zealand surrender warrant has been executable for more than one month while the person remains detained in Australia; reasonable notice to the Attorney-General is required, and section 38(8) preserves custody where life, health or another reasonable cause explains the delay. This is not a one-month maximum from arrest.

What happens after eligibility is established, and can an Australian citizen be extradited?

Under section 22, the Attorney-General must consider the statutory preconditions, including extradition objections, torture risk, death-penalty undertakings when relevant, speciality assurances, country-specific treaty limitations and the ultimate discretion whether to surrender. This executive assessment is distinct from what the magistrate or eligible judge decides. The High Court's Minister for Home Affairs v Zentai [2012] HCA 28 illustrates why the treaty and implementing regulations matter: the Court upheld the setting aside of surrender in a Hungary case because of the specific treaty's offence-at-the-time requirement. It is not a universal Australian rule that all treaty requests fail whenever an offence definition has changed.

Australian or dual citizenship is no general immunity, but treaty-specific restrictions still require assessment. A refusal under section 22(5) leads to release or discharge of recognisances, not an assumption of surrender.

Section 23 ordinarily requires a surrender warrant; section 24 permits temporary surrender of an Australian prisoner with conditions, including return undertakings. Immigration removal and extradition are different. Australia is outside the ECtHR system: Rule 39 is not an Australian extradition remedy. Once a Part II surrender warrant is first liable to be executed, section 26(5) permits a person still detained in Australia more than two months later to apply to the Federal Court for release, giving reasonable notice to the Attorney-General. Section 26(6) blocks release if the delay was caused by danger to the person's life, prejudice to health, or another reasonable cause. This is not an automatic two-month cap from arrest or from the date a warrant is signed.

What should an extradition lawyer and the family do now?

In the first practical working period—not a purported statutory “72-hour deadline”—establish the person's location and the basis of detention, request access to Australian criminal and extradition counsel, and avoid signing a consent or waiver that has not been explained. Ask whether the family is dealing with a section 12 warrant, a section 16 notice or an indorsed New Zealand warrant; the choice changes almost everything that follows. Keep a single timeline of arrest, appearances, notices, orders and service dates, including the date a section 19 or 34 order was actually made.

• Send counsel a copy of the arrest warrant, charge list, formal foreign request, section 16 notice and translated supporting documents, where available.
• Identify all passports and citizenships; collect reliable proof of name, date of birth and any possible mistaken identity.
• Supply the Australian remand and bail orders, hearing notices, medical and custody information, and contact details for a trusted relative.
• Preserve foreign judgments, warrants, evidence of sentence already served and existing legal proceedings, without altering or withholding records.
• Record the actual order date and any imminent review deadline; distinguish a section 21 review from a challenge to the Attorney-General's separate section 22 determination.
• Ask about an interpreter and, where eligible, legal aid. Victoria Legal Aid's published guideline, for example, covers possible grants for section 19 proceedings and section 21 review, subject to assessment.

Hypothetical example. An Australian–Croatian dual national is arrested in Melbourne on a section 12 warrant concerning alleged conduct abroad. Counsel first checks that Croatia is covered by the current regulations, obtains the warrant and any section 16 notice, and seeks remand and bail advice under section 15. If the court-facing eligibility stage is reached, counsel prepares an offence-by-offence review of the authenticated records rather than conducting a trial of guilt. If section 19 eligibility is found, the 15-day section 21 clock becomes immediate; the Attorney-General's later section 22 decision remains a different step. None of those decisions is resolved simply by producing an Australian passport.
