Cannabis Cultivation Charges in Victoria Explained

Cannabis Cultivation Charges in Victoria Explained

Direct answer

Growing cannabis is illegal in Victoria, and how serious the charge is depends almost entirely on the number of plants. It ranges from up to 1 year for a small crop the court accepts was not for sale, up to 25 years for a commercial quantity of 100 plants or more. The line between a personal crop and a commercial one is where these cases are won or lost.

This guide explains the cannabis cultivation offences in Victoria, the plant and weight thresholds that separate a personal crop from a commercial one, the penalties at each level, how “deemed trafficking” works, and the defences and diversion options that can keep a matter out of the serious range.

Key takeaways

  • Cultivating cannabis is illegal in Victoria, and the number of plants is the single biggest factor in how serious the charge is.
  • A small crop the court accepts was not for trafficking can carry as little as 1 year or a fine, while a commercial quantity carries up to 25 years.
  • The key thresholds for cannabis are 10 plants (trafficable), 100 plants (commercial), and 1,000 plants (large commercial).
  • Cultivating a trafficable quantity or more can be treated as cultivation for the purpose of trafficking, which is far more serious.
  • Whether the crop was for personal use or for sale is the central battleground in most cases.
  • Diversion and cannabis cautioning can keep some lower-level matters out of the courts entirely.

Plain-English definitions

Cultivate

Defined broadly in the law to include sowing, planting, growing, tending, nurturing, and harvesting a plant, so almost any involvement in growing can count.

Narcotic plant

A plant such as cannabis, opium poppy, or coca. Cannabis is by far the most commonly charged in Victoria.

Small quantity

Up to 50 grams of cannabis, the level most likely to be dealt with by a caution rather than a charge.

Trafficable quantity

250 grams or more, or 10 plants or more of cannabis. At this level the law can treat cultivation as being for trafficking.

Commercial quantity

25 kilograms or more, or 100 plants or more of cannabis, carrying a maximum of 25 years.

Large commercial quantity

250 kilograms or more, or 1,000 plants or more of cannabis, the most serious cultivation tier.

Deemed trafficking

Where cultivating a trafficable quantity or more raises a legal presumption that the cultivation was for the purpose of sale.

Diversion

A way of resolving a suitable lower-level matter without a criminal conviction, often with conditions.

Legal process timeline

  1. 1

    Police detect the crop

    A crop is found through a search warrant, a traffic stop, a tip-off, or an unrelated investigation.

  2. 2

    Plants are seized, counted, and weighed

    The number of plants and the total weight are recorded, because these figures determine the charge.

  3. 3

    The charge is selected by quantity

    Police and prosecutors choose the charge based on the plant count and weight, and on whether trafficking is alleged.

  4. 4

    Bail or a summons

    You are either bailed with conditions or summonsed to attend court, depending on the seriousness.

  5. 5

    The matter is listed in court

    Smaller matters are heard in the Magistrates' Court, while commercial quantities are dealt with in the County Court.

  6. 6

    Plea or contest

    You either accept responsibility or contest the charge, including any dispute over whether the crop was for sale.

  7. 7

    The outcome

    The result ranges from diversion or a fine to a community order or, for commercial quantities, imprisonment.

About this guide

Legal basis

This guide is based on the cultivation offences and quantity thresholds in the Drugs, Poisons and Controlled Substances Act 1981 (Vic), together with how these matters are dealt with in the Magistrates’ and County Courts of Victoria.

How this guide was prepared

Drafted for people who need a plain-English explanation of how cannabis cultivation charges work in Victoria, based on the practical questions people ask after plants are seized or a charge is laid.

Important limits

  • The precise outcome for your individual plant numbers and history
  • Medicinal cannabis, which is lawful under a separate regulated scheme
  • Trafficking, possession, or importation charges on their own facts
  • Commonwealth drug offences
  • The exact current dollar value of a penalty unit fine

The correct answer for your situation depends on the number of plants, the total weight, whether the crop is alleged to be for sale, and your circumstances.

In-depth analysis

Is it illegal to grow cannabis in Victoria?

Yes. It remains against the law to use, possess, cultivate, or traffic cannabis in Victoria, and that includes growing even a single plant at home. Despite changing attitudes and the availability of lawful medicinal cannabis through a separate regulated scheme, recreational cultivation has not been legalised, and a home grow is a criminal offence. Understanding what happens after being charged is a useful starting point if police have already taken action.

The important nuance is that not all cultivation is treated equally. The law draws sharp lines based on how many plants are involved and whether the crop is considered to be for personal use or for sale, and those lines are what separate a minor matter that may be diverted from a serious charge carrying years in prison.

What counts as “cultivation”?

More than most people expect. The legal meaning of cultivate is deliberately broad, covering sowing, planting, growing, tending, nurturing, and harvesting a plant. That means you do not have to own the crop or profit from it to be charged, because simply watering or caring for plants can be enough to make you a cultivator in the eyes of the law.

This breadth catches people out, particularly where several people share a house or a property. Anyone who plays a role in growing the plants can potentially be charged, which is why the exact facts of who did what matter so much, and why early advice about your specific involvement is worth getting before you say anything to police.

What are the cannabis cultivation offences and penalties?

Victorian cultivation offences sit on a tiered scale under the Drugs, Poisons and Controlled Substances Act 1981, and the tier is set by the quantity and by whether the crop was for trafficking. The table below sets out the main cultivation offences and their maximum penalties.

OffenceSectionMaximum penalty
Cultivating a small crop, not for traffickings72B1 year and/or 20 penalty units
Cultivating a narcotic plant (for trafficking)s72B15 years and/or 1,800 penalty units
Cultivating a commercial quantitys72A25 years and/or 3,000 penalty units
Cultivating a large commercial quantitys7225 years and/or 5,000 penalty units

The most important feature of this scale is the special position of a small crop. Where the court is satisfied that a plant was not cultivated for the purpose of trafficking, the maximum drops dramatically, to 1 year or a fine, rather than 15 years. That single finding, personal use rather than sale, is often the whole contest in a cannabis case, and the Sentencing Advisory Council publishes data showing how the higher tiers are dealt with in practice.

How do the plant thresholds work?

The thresholds are defined by both plant numbers and weight, and reaching either one is enough. For cannabis, the key figures set the boundaries between the offence tiers, and the table below sets them out.

Quantity levelCannabis thresholdWhat it means
Small quantityUp to 50 gramsMost likely a caution for a first offence
Trafficable quantity250 grams, or 10 plantsCan be treated as cultivation for trafficking
Commercial quantity25 kilograms, or 100 plantsUp to 25 years, a very serious charge
Large commercial quantity250 kilograms, or 1,000 plantsThe most serious cultivation offence

Because the plant count alone can push a matter across a threshold, the difference between 9 and 10 plants, or 99 and 100, is not trivial. It can be the difference between a matter that stays in the Magistrates’ Court and one that heads to the County Court with a real risk of imprisonment, which is why the accuracy of the count and weight is sometimes itself worth challenging.

What is deemed trafficking?

Deemed trafficking is one of the harshest features of drug law, and it catches many people by surprise. Where a person cultivates a trafficable quantity, meaning 250 grams or 10 plants or more, the law can presume that the cultivation was for the purpose of sale, rather than requiring the prosecution to prove it separately. In effect, the burden shifts, and it becomes the accused’s task to show the crop was for personal use.

This is why the personal-use argument is so central. If you can satisfy the court that a crop above the threshold was genuinely for your own use, the charge and penalty can fall away sharply, and this is exactly the kind of issue where a case can be downgraded or dropped with the right evidence and approach. Getting the framing right from the start is critical.

Which court will hear a cultivation charge?

That depends on the quantity. A small cultivation matter, particularly one accepted as being for personal use, is generally heard in the Magistrates’ Court, where the outcomes are far less severe and diversion may be possible. Larger matters, especially commercial and large commercial quantities, are indictable and are dealt with in the County Court, where imprisonment is a realistic outcome.

The stakes rise sharply with the court. A commercial cultivation charge is treated as a category 2 offence, which means a court must generally impose a custodial sentence unless particular circumstances apply. That makes the classification of the charge, and any argument to reduce it, enormously important, and you can see how we defend drug offence charges at this level. Where a matter can be kept in the lower court, the difference to a person’s life can be profound.

What are the defences, and can you avoid a conviction?

Several real defences and outcomes exist, depending on the facts. The most common is the personal-use argument, aimed at defeating the presumption of trafficking and keeping a matter in the lower tier. Others focus on whether you actually cultivated the plants at all, particularly in shared households, and on whether the search and seizure were lawful.

At the lower end, a first-time matter involving a small quantity may be resolved without a conviction at all, through the cannabis cautioning program or through diversion, which allows the charge to be dealt with without a criminal record.

Even where a conviction is a possibility, the outcome is far from fixed, and the way a case is presented can be the difference between a record and a clean result, so it is worth understanding how long a criminal record lasts before deciding how to approach the matter.

Our case study of a cannabis cultivation matter resolved on a community-based disposition shows how even a serious charge can be steered away from imprisonment.

Sometimes the strongest step of all is arguing for the charge to be dropped before court where the evidence is weak, particularly if the plants were not yours or the search was unlawful.

Scenario-based guidance

If police have seized your plants

Confirm the exact number of plants and the total weight alleged, because these figures determine the charge and the tier.

If it was a small crop for personal use

The argument that the cannabis was not cultivated for trafficking is central, and it can drop the maximum penalty dramatically.

If you were at or over 10 plants

Deemed trafficking may apply, meaning the law can presume the crop was for sale unless you show it was for personal use.

If a commercial quantity is alleged (100 plants or more)

This is a category 2 offence carrying up to 25 years, where a court must generally impose a custodial sentence, so experienced representation is essential.

If it is your first offence with a small quantity

Cannabis cautioning or diversion may be available, allowing the matter to be resolved without a criminal record.

If others share the property

Who actually cultivated the plants matters, because a role in growing them is what makes a person a cultivator in law.

Practical checklist

If you are facing a cannabis cultivation charge:
  • Do not speak to police about the crop before getting legal advice.
  • Confirm the exact number of plants and the total weight alleged.
  • Note whether the charge alleges cultivation for trafficking.
  • Gather any evidence that the crop was for personal use, if that is the case.
  • Do not discuss the matter over the phone or on social media.
  • Ask whether the plant count or weight can be challenged.
  • Ask whether diversion or cannabis cautioning is available.
  • Understand which court your matter will be heard in.
  • Get advice on whether a conviction can be avoided.
  • Act early, while the classification of the charge can still be influenced.

Common mistakes

  • Assuming a home grow is legal or too minor to be charged.
  • Not realising that watering or tending plants can count as cultivation.
  • Underestimating how much a single plant over a threshold changes the charge.
  • Admitting the crop was for sale before getting advice.
  • Failing to gather evidence that a crop was for personal use.
  • Assuming the presumption of trafficking cannot be challenged.
  • Overlooking diversion or cannabis cautioning for a small first matter.
  • Treating a commercial charge as something that can be handled without a lawyer.
  • Discussing the matter with police or online.
  • Leaving advice until after the first court date.

Questions to ask your lawyer

  • How many plants and what weight are alleged, and which tier does that put me in?
  • Is the charge cultivation for trafficking, and can that be challenged?
  • Can I argue the crop was for personal use?
  • Can the plant count or weight be disputed?
  • Is diversion or cannabis cautioning available to me?
  • Which court will hear my matter, and what does that mean?
  • Is imprisonment a realistic risk for my charge?
  • Can a conviction be avoided?
  • Were the search and seizure lawful?
  • What can I do now to put myself in the best position?

Frequently asked questions

No. Growing cannabis at home is illegal in Victoria, even a single plant for personal use. Medicinal cannabis is available through a separate regulated prescription scheme, but recreational cultivation remains a criminal offence, though a small first-time crop may be dealt with by a caution or diversion rather than a conviction.

The key thresholds are 10 plants, which is the trafficable quantity that can trigger a presumption of trafficking, 100 plants for a commercial quantity carrying up to 25 years, and 1,000 plants for a large commercial quantity. Below 10 plants, a matter is more likely to be treated as personal cultivation.

It depends on the quantity. A small crop the court accepts was not for trafficking carries up to 1 year or a fine, cultivation for trafficking carries up to 15 years, and a commercial or large commercial quantity carries up to 25 years. Plant numbers and the purpose of the crop drive the penalty.

Sometimes. A first-time matter involving a small quantity may be resolved through the cannabis cautioning program or diversion, which avoids a criminal record. For larger matters a conviction is more likely, but the outcome still depends heavily on the plant numbers, the purpose of the crop, and how the case is presented.

Cultivating a trafficable quantity, meaning 250 grams or 10 plants or more, can raise a legal presumption that the crop was for sale. This shifts the burden onto the accused to show the cannabis was for personal use. Defeating that presumption is often the central issue in a cultivation case.

Self-defence is a complete defence to assault in Victoria. Under section 322K of the Crimes Act 1958, you are not guilty if you believed your conduct was necessary and it was a reasonable response in the circumstances as you saw them. The prosecution must disprove it.
Using a mobile phone illegally while driving in Victoria carries a $627 fine and 4 demerit points, under the Road Safety Road Rules 2017. Learner and P-plate drivers cannot use a phone at all, and detection cameras now enforce the rules automatically.
Driving when you have never held a licence is an offence under section 18 of the Road Safety Act 1986, carrying up to 60 penalty units or 6 months imprisonment. That is far more than the penalty for an expired licence, and the court can also delay when you may apply for a licence.
