Jurisdiction-by-Jurisdiction Breakdown
Strip Search Rules — What Police Must Follow
Strip searches during drug enforcement are among the most invasive exercises of police power. Every Australian jurisdiction imposes additional requirements beyond standard search powers. These are not optional — they are procedural safeguards that apply even when the underlying search is lawful.
Requirements Across All Jurisdictions
- Same-sex officer: A strip search must be conducted by an officer of the same sex as the person being searched (in most jurisdictions).
- Private location: Strip searches cannot be conducted in public view. A screen or private area must be used.
- No more intrusive than necessary: Officers cannot demand removal of all clothing simultaneously — items should be removed and returned progressively.
- No physical contact with genitals: A strip search does not authorise touching. An officer may require you to lift clothing, squat, or turn around — not touch your body.
- Support person: In NSW and some other jurisdictions, police must offer you a support person before conducting a strip search.
- Written record: Police must record the strip search in writing, including the grounds and what was found.
- Minors — additional protections: A strip search of a person under 18 requires a parent, guardian, or support person to be present in most jurisdictions.
Intimate Search (Body Cavity)
An "intimate search" involving inspection or examination of body cavities cannot be conducted by a police officer in any Australian state. It must be performed by a medical practitioner. Only a court order or specific legislative authority permits an intimate search — it is not within standard drug search powers.
During a Strip Search — Do
- Ask clearly: "Are you conducting a strip search?" — get it on record
- Ask for the grounds: "What are the grounds for this strip search?"
- Request a same-sex officer if the officer present is not the same sex
- Request a support person (in NSW and where available)
- Comply physically — challenge legality in court afterward
- Note the officer's name, badge number, and time
- Contact a lawyer immediately after
During a Strip Search — Don't
- Physically resist — this adds an "obstruct police" charge
- Voluntarily consent without understanding your rights
- Allow an intimate search without a medical practitioner present
- Agree to be searched in a public or semi-public location
- Answer questions about what they might find — exercise silence
- Sign any documents you haven't read or don't understand
Sniffer Dog Laws by State
Drug detection dogs are widely used by police across Australia — particularly at music festivals, train stations, and entertainment precincts. Their legal basis and the rights you have differ by state.
Key Facts About Sniffer Dogs
- NSW is the highest-use state: The Dogs Act 2007 authorises drug detection dogs in trains, stations, buses, licensed premises, and at declared events without any reasonable suspicion for the individual.
- A dog alert creates reasonable grounds: In NSW and QLD, a positive indication from a drug detection dog can satisfy the reasonable suspicion threshold for a personal search. The law was upheld in R v Darby [2010] NSWSC.
- High false positive rates: Research (UNSW, 2021) showed NSW sniffer dogs had a false positive rate of approximately 60–80% at festivals. An alert alone does not guarantee drugs are present.
- You cannot obstruct the dog: You must not prevent the dog from approaching — but you are not required to stop, assist, or engage with the handler beyond lawful compliance.
- If nothing is found: If police search you following a dog alert and find nothing, you have not committed an offence. The search was based on reasonable grounds even if those grounds proved incorrect — but your conduct during the search was lawful.
| State | Legal basis for dogs | Where deployed | False positive legal exposure |
|---|---|---|---|
| NSW | Dogs Act 2007 | Public transport, festivals, licensed venues, declared areas | None — alert creates grounds for search, not offence |
| QLD | PPRA 2000 | Public events, transport, declared areas | None — alert creates grounds for search |
| VIC | Limited — specific legislative powers | Transport, events (more restricted than NSW/QLD) | None if search lawfully follows |
| WA | Misuse of Drugs Act 1981 | Transport, events, border areas | None if search lawfully follows |
| SA / TAS / NT / ACT | Various state powers | Less frequent — targeted operations | None if search lawfully follows |
| AFP / Federal | Customs Act 1901 (Cth); Crimes Act 1914 (Cth) | Airports, borders — near-unlimited powers | None at border — very broad powers apply |
Roadside Drug Testing — Your Rights and Obligations
Roadside drug testing (RDT) operates in all Australian states and territories. Unlike breath testing (which detects BAC), RDT detects the presence of specific drug substances in saliva. You are legally required to comply.
Substances Tested
- THC (cannabis — active compound)
- Methylamphetamine (meth, ice, speed)
- MDMA (ecstasy)
- Cocaine (some jurisdictions)
How the Test Works
- Police require you to provide a saliva sample via an oral swab.
- If the initial test is negative — you are free to go.
- If the initial test is positive — you wait for a second confirmatory test (usually 30 minutes).
- If the second test is positive — police may require a blood sample for laboratory analysis.
- Laboratory confirmation is required before a charge is laid in most jurisdictions.
Refusal Penalties by State
| State | Refusal offence | Penalty (approx.) | Immediate licence suspension |
|---|---|---|---|
| NSW | Refuse drug test under Road Transport Act 2013 | Fine up to $3,300 + disqualification | Yes — immediate suspension |
| VIC | Refuse drug test under Road Safety Act 1986 | Fine up to $5,413 + disqualification | Yes — immediate suspension |
| QLD | Refuse drug test under Transport Operations (Road Use Management) Act 1995 | Fine up to $4,000 + disqualification | Yes — 24-hour suspension minimum |
| WA | Refuse drug test under Road Traffic (Driving Standards) Regulations 2017 | Fine + disqualification | Yes |
| SA | Refuse drug test under Road Traffic Act 1961 | Fine + disqualification | Yes |
| TAS | Refuse drug test under Traffic Act 1925 | Fine + disqualification | Yes |
| NT | Refuse drug test under Traffic Act 1987 | Fine + disqualification | Yes |
| ACT | Refuse drug test under Road Transport (Alcohol and Drugs) Act 1977 | Fine + disqualification | Yes |
Important: THC can remain detectable in saliva for up to 12 hours after cannabis use, and in blood for days to weeks depending on frequency of use. Testing positive does not require that you were impaired at the time of driving in most jurisdictions — the presence of the substance alone is sufficient for a charge.
What To Do If Police Find Drugs
Your conduct in the minutes after drugs are found is critical. Statements made to police before you speak to a lawyer are routinely used as evidence — and people frequently incriminate themselves by trying to explain the situation.
-
1Stay calm and do not physically resist. Physically resisting police after drugs are found adds charges (obstruct police, resist arrest) that compound the original offence. Comply with lawful instructions.
-
2Exercise your right to silence — immediately. Say: "I want to speak to a lawyer before answering any questions." Then stop talking. Everything you say can be used as evidence. "They're not mine" and "I was holding them for someone" are two of the most commonly given statements that worsen outcomes at trial.
-
3Note whether the search was lawful. Mentally note: Did police state reasonable grounds? Was a strip search conducted correctly? Were procedural requirements followed? These details matter for any legal challenge.
-
4Record the officer's details. Badge number, name, station, time, location, and what was said. Do this as soon as you are able.
-
5Do not consent to further searches. If police want to search further (your home, your car, your devices), say: "I do not consent to any further searches." This does not prevent a lawful search — it ensures any unlawful search can be challenged later.
-
6Contact a lawyer before the charge is formally laid. Legal aid is available in every state. Call the Legal Aid hotline for your state, a duty solicitor at the police station, or a private criminal defence lawyer. Early legal advice can significantly affect outcomes.

Drug Possession Penalties by State
Penalties for drug possession vary widely across Australia — from expiation notices (SA, ACT for cannabis) to serious criminal offences with imprisonment. The quantity, type of drug, and intent (personal use vs. supply) are all relevant.
| State | Cannabis (personal use) | Other drugs (personal use) | Supply / trafficking |
|---|---|---|---|
| NSW | Criminal offence — fine and/or up to 2 years imprisonment; caution scheme for first offence (Cannabis Cautioning Scheme) | Criminal — fine/imprisonment up to 2 years | Up to life imprisonment (commercial quantities) |
| VIC | Under 50g — infringement notice (A$316); over 50g — criminal offence | Criminal — fine/imprisonment (court discretion) | Up to life imprisonment for trafficking |
| QLD | Criminal offence — drug diversion available | Criminal — fine/imprisonment | Up to 25 years imprisonment |
| WA | Under 10g — cannabis infringement notice; over 10g — criminal offence | Criminal — fine/imprisonment | Up to 25 years imprisonment |
| SA | Under 25g — expiation notice (fine, no criminal record if paid) | Criminal — fine/imprisonment | Up to life imprisonment |
| TAS | Criminal offence — no expiation scheme | Criminal — fine/imprisonment | Up to 21 years imprisonment |
| NT | Criminal offence — mandatory sentencing applies to repeat offenders | Criminal — mandatory minimums may apply | Up to life imprisonment |
| ACT | Under 50g — Simple Drug Offence Notice (health referral, no criminal record) since Oct 2023 | Under threshold amounts — SDON (health referral); over threshold — criminal | Up to life imprisonment for trafficking |
| Federal | N/A (state offences generally apply) | Criminal — applies to importation, cross-border trafficking | Up to life imprisonment — commercial importation carries some of the harshest penalties in Australian law |
Frequently Asked Questions
Can police search you at a music festival without any reason?
In NSW, certain festivals declared under the LEPRA or the Summary Offences Act allow police to use drug detection dogs without needing any prior suspicion about an individual. If the dog indicates, that provides grounds for a personal search. In other states, police generally still need reasonable suspicion before conducting a personal search at a festival, though the presence of sniffer dogs and the nature of the event can provide that context.
Always ask: "What are the grounds for your search?" This creates a record. If police cannot articulate grounds, note this — it is relevant to any later challenge to the admissibility of evidence found.
What if the drugs belong to someone else? Are you still liable?
"They're not mine" is rarely an effective legal defence — and saying it to police before speaking to a lawyer almost always makes things worse. Possession under criminal law does not require ownership; it requires knowledge and control. If drugs are found in your bag, your car, or on your person, you may be presumed to have possession even if you claim they belong to someone else.
The legal question of joint possession (multiple people in a car where drugs are found) is fact-specific and depends on who had knowledge and control. A lawyer can advise on whether "constructive possession" applies in your specific circumstances. Do not discuss this with police — exercise silence and get legal advice.
Can you be charged for drug paraphernalia even if no drugs are found?
Yes. Possession of drug paraphernalia (pipes, bongs, foil, syringes associated with drug use, scales) is an offence in most Australian states even without any drugs being present. In NSW, it is an offence to have a "prohibited drug implement." In QLD, the Drugs Misuse Act covers possession of utensils. VIC's Drugs, Poisons and Controlled Substances Act similarly prohibits drug paraphernalia in certain circumstances.
A drug detection dog alerting to paraphernalia with drug residue is generally sufficient for a search and potentially a charge. Clean paraphernalia (e.g., sealed, unused) may attract less scrutiny but is still technically illegal in most states.
Does exercising your right to silence make you look guilty?
No — in Australian law, a jury or court cannot draw an adverse inference from your silence alone. The right to silence is a fundamental legal protection, and exercising it is not evidence of guilt. Police may push back ("just tell us what happened and we can sort this out") — this is an interview technique. The courts have consistently held that exercising the right to silence is lawful conduct and cannot be used against you at trial.
The phrase to use: "I want to speak to a lawyer before answering any questions." Then stay silent. This applies regardless of whether you are arrested or simply being questioned.
What happens to drugs seized by police if you're found not guilty?
Drugs are not returned to you even if you are found not guilty. Prohibited substances have no legal right of ownership — they cannot be returned. If you are acquitted, the drugs will be destroyed by police. If you are seeking return of other property seized alongside the drugs (e.g., cash, a phone), you may apply to the relevant court or police property section under the applicable legislation (e.g., LEPRA s 222 in NSW). Contested money is more complex — contact a lawyer if significant cash was seized.
Can you legally swallow drugs to avoid detection during a search?
Deliberately concealing evidence (including by swallowing it) can constitute an additional offence — "wilfully destroying or concealing evidence" or "obstruction of justice" — on top of any drug offence. Beyond the legal risk, swallowing large quantities of drugs creates a serious medical risk (overdose, drug toxicity, foreign body complications). From a legal strategy perspective: your right to silence is always available and safer than actively destroying evidence. Never take actions during a police interaction that risk your physical health or escalate the charges.
Can cannabis detected on a drug dog alert lead to a conviction if the amount is tiny?
Potentially yes, depending on the jurisdiction. In NSW, the Cannabis Cautioning Scheme gives police discretion to issue a caution rather than a charge for first or second minor possession offences (under 15g). However, this is a discretionary power — police can still charge you. Drug detection dogs are extremely sensitive and can alert to very small quantities or residue. If a positive alert leads to a search and traces are found, the outcome depends on the quantity, your prior record, and the exercise of police and prosecutorial discretion.
In the ACT, under the 2023 decriminalisation scheme, possession under 50g cannabis results in a health referral — not a criminal charge. In VIC, under 50g results in an infringement notice. In other states, even trace amounts can technically ground a criminal charge, though diversion programs may be available.
What should you say if police ask you to explain why the dog alerted?
Nothing. Exercise your right to silence. Police asking you to explain a drug dog alert is an attempt to get you to either confirm drug use/possession or make a statement that can be used against you. The correct response is: "I don't wish to answer questions without speaking to a lawyer first." You are not required to explain the dog's behaviour, account for your whereabouts, or justify anything during a street search. State your name (if required by law in your jurisdiction), comply with any lawful physical search, and stay silent on everything else.
