Police Powers in Queensland
Police powers are real, and they are conditional. Knowing which is which, at the moment it matters, is the difference between cooperating and conceding.
Police powers in Queensland come principally from the Police Powers and Responsibilities Act 2000. You must give your name and address in prescribed circumstances, but you are generally not obliged to answer other questions. Searches without a warrant are permitted only on specified grounds. Before a formal interview about an indictable offence, police must caution you, and you have the right to contact a friend, relative or lawyer.
What you must provide, and what you need not
There is a narrow set of circumstances in which you are required to give your name and address to a police officer — broadly, where you are suspected of having committed an offence, where you are the driver of a vehicle, or where another specific power is being exercised. Giving false details is itself an offence.
Beyond that, the general position is that you are not obliged to answer questions. The right to silence is real, it applies during informal roadside conversation as much as in a formal interview, and exercising it is not evidence of guilt. There are limited statutory exceptions — for example certain obligations on vehicle owners to identify a driver — but they are exceptions rather than the rule.
It is worth being clear about why this matters practically. An account given early, before anyone has considered what lawful excuse or defence might be available, cannot be withdrawn. It can narrow what is arguable months later, and it is the single most common way a defensible matter becomes an indefensible one. Declining to be interviewed until you have advice preserves your position rather than damaging it.
A useful and entirely proper thing to say is: "I do not wish to answer questions until I have spoken to a lawyer." Say it once, politely, and repeat it if pressed. Nothing further is required of you.
Searches
Police may search with a warrant, with your consent, or without a warrant where a specified statutory ground exists — for example a reasonable suspicion that a person is carrying an unlawful dangerous drug, a weapon, or something that may be evidence of an offence. The grounds are set out in the legislation and they are not open-ended.
Consent is the point at which most searches become lawful. If you consent, the question of whether a ground existed largely falls away. You are entitled to decline consent and to ask what power is being relied on instead. Declining is not obstruction, and it does not prevent a lawful search proceeding — it simply means the lawfulness will rest on the power rather than on your agreement.
Where evidence has been obtained by a search that exceeded the power relied on, a court has a discretion to exclude it. In a drug matter, if the excluded material is the drug itself, the prosecution case may not survive. This is why the lawfulness of the search is examined in most such matters, and why what was said at the roadside is worth recording accurately afterwards.
Mobile phones and other digital devices are treated separately and the law in this area has developed quickly. If police ask for a passcode, that is a question worth getting advice on rather than answering reflexively.
Move-on directions
Police may direct a person to leave a place and not return for a stated period, in prescribed circumstances and in relation to prescribed places. A direction must be reasonable in the circumstances, and failing to comply with a lawful direction is an offence.
Two practical points. A direction should be identifiable as a direction rather than as advice, so it is fair to ask whether you are being formally directed. And a direction that is not lawfully given is not one you can be convicted of contravening — but that is an argument for a courtroom, not for the footpath. Comply, then get advice.
If you are arrested or detained for questioning
Police may detain a person for a reasonable time for questioning about an indictable offence, subject to statutory limits and safeguards. Before questioning you about such an offence, they must caution you that you do not have to answer and that anything you say may be used in evidence.
The Police Powers and Responsibilities Act 2000 is long and heavily amended, and the grounds, time limits and safeguards summarised here are subject to conditions not set out on this page. Section numbers and periods are deliberately not reproduced. Confirm the current provisions against the legislation. See sources 1 and 2.
