If police have found drugs in your car or your house and they were not yours, that is a real argument. It is also one of the few places in Queensland criminal law where the work shifts onto you, and knowing which situation you are in changes what you should be doing this week.

What possession actually requires

Possession is not the same as being nearby.

Legal Aid Queensland's material describes the requirement as knowing of the thing's existence, and having laid claim to it or exercised some control over it. So a passenger who genuinely had no idea what was in the console is not in possession of it simply by sitting next to it.

There is a further point worth knowing. The prosecution has to prove you knowingly possessed a thing that was in fact a dangerous drug. They do not have to prove you knew what the substance was. That means "I didn't know what it was" is a much weaker position than people expect, while "I didn't know it was there" is a genuinely different and much stronger argument.

There is also a floor on quantity. Legal Aid Queensland notes that a quantity incapable of being discerned by the naked eye cannot sustain a conviction. The amount has to be enough that it makes sense, as a matter of common sense and reality, to say it is the drug.

More than one person can possess the same drugs

This surprises people who assume the police have to pick someone.

Possession can be joint. Two or three people in a car can each be in possession of the same drugs at the same time, if the elements are made out against each of them. Everybody being charged does not mean somebody is being charged wrongly, and it does not mean the charges will sort themselves out later.

Possession can also be constructive rather than physical. You do not have to be holding something to possess it.

The rule that flips the work onto you

Here is the one that matters most, and it applies to a lot of share house and vehicle situations.

Legal Aid Queensland describes a provision in the Drugs Misuse Act that applies to the occupier of a place, or a person concerned in its management or control. Where drugs are proved to have been at that place, that is treated as conclusive evidence that the occupier was in possession of them, unless that person shows they neither knew nor had reason to suspect the drug was there.

Two things follow, and they are the whole point of this article.

The burden moves. Normally the prosecution proves everything. Here, once the drugs are shown to have been at the place, it is on you to show you did not know and had no reason to suspect.

The standard you have to meet is lower than the criminal standard. Legal Aid Queensland describes the defendant carrying it on the balance of probabilities, which means more likely than not, rather than beyond reasonable doubt.

So the position is not hopeless, and it is also not something that resolves itself by you telling police the drugs were not yours.

What "neither knew nor had reason to suspect" actually needs

More than a denial. This is where these matters are won and lost.

Who else had access to the place or the vehicle, and can that be shown rather than asserted. Tenancy agreements, keys, messages arranging for someone to stay, a housemate's own admissions.

Where the drugs were found. Something in a locked container belonging to somebody else sits very differently from something in the console of a car you drive daily.

Whether there was anything that should have put you on notice. The words "reason to suspect" do real work. A person who knew perfectly well what a housemate was doing and chose not to look at it is in a different position from a person who genuinely had no idea.

What you said at the scene. An early, clear, consistent account is worth a great deal. A rushed one that changes later is worth very little.

The practical instruction that follows is unglamorous: start gathering that material now, while people are still contactable and messages still exist.

An important limit on that rule

Legal Aid Queensland's material makes a point that is easy to miss and useful to know. That deeming provision applies to dangerous drugs. It does not apply to things.

So scales, bags and utensils found in your house are not swept up by the same rule. For those, the prosecution has to prove the ordinary elements against you.

That distinction is worth raising, because charges frequently arrive as a bundle and the bundle is not all equally strong.

Cash found at the same time

Cash tends to come with its own charge. Legal Aid Queensland describes an offence of possessing property reasonably suspected of being connected with drug offending, carrying a maximum of two years, where the person has to give the court a satisfactory account of how they lawfully came by the property.

If there is a legitimate explanation for money found at your place, the documents that prove it are the answer. Payslips, bank records, a sale receipt. Again, that is material to assemble now rather than to describe from memory later.

Letting other people use your place

There is a separate and much more serious offence for occupiers.

Legal Aid Queensland describes an offence where a person who is the occupier, or concerned in the management or control of a place, permits it to be used for the commission of a drug crime, carrying a maximum of 20 years. It requires knowledge, and suspicion alone is not enough, though Legal Aid Queensland notes knowledge can be inferred where a person shuts their eyes to suspicious circumstances.

That is the charge to be alert to if the real situation is that you knew what was going on in your house and did nothing about it. It is a very different offence from possession.

Could police search you in the first place

Often, yes.

The Queensland Law Handbook describes police as having wide powers under the Police Powers and Responsibilities Act to search a person, premises or a vehicle with or without a warrant, particularly where an officer reasonably believes the person is in possession of drugs. Drug detection dogs can also be used without a warrant in certain circumstances.

So the search being unexpected, or feeling unfair, does not make it unlawful. Whether a particular search was properly conducted, and what follows if it was not, is a specific question about your matter rather than a general rule, and it is one worth having looked at rather than assumed either way.

What actually drives the penalty if it does come back to you

The maximums in this area are high and they are ceilings for the worst version of an offence, not forecasts. Nobody can tell you what your matter will produce.

What moves a sentence within the range is which drug it was, how much, whether a commercial purpose is alleged, which court deals with it, your history and what you have done since, your plea and when you entered it, and separately whether a conviction is recorded at all. Our page on drug possession covers how possession matters are dealt with.

What to do this week

Get the QP9 and read where police say each item was found and what they say connects it to you.

Do not explain. Saying whose you think the drugs were, or what they were for, creates problems that did not exist before you spoke.

Write down who had access to the vehicle or the place, and over what period, with dates.

Preserve messages. Do not delete anything, and do not upgrade or wipe your phone.

If drugs have been found somewhere you live or drive in Cairns

The question in these matters is rarely what the penalty is. It is whether the prosecution can connect the drugs to you at all, and if a deeming provision applies, what evidence you can put up in answer.

We act in drug offences matters in Cairns and across Far North Queensland. If drugs have been found in a car or a house connected to you, the material that answers these charges disappears quickly, so it is worth acting early.

If drugs have been found in a car or a house connected to you in Cairns, speak with us early, while the material that answers it still exists.
