Supply means handing a banned drug to someone else — selling it, giving it away, or even just offering to. It doesn't matter if no money changes hands; passing it on is enough. Trafficking is the bigger version: doing it regularly, on a commercial scale, or as part of an organised operation. These are the most serious drug charges, and they carry the heaviest penalties.
The whole idea in one picture
From handing it over to hard time
Supply starts the moment a drug is passed on — sold, given, or just offered. Scale it up and it becomes trafficking. Here's how that escalates, and what's waiting at the end.
Supply vs trafficking
They're related, but trafficking is the more serious step up. The line is mostly about scale and whether it's an ongoing operation.
Supply
Selling a drug
Giving it away — even for free
Sharing it with friends
Just offering to supply
Trafficking
Ongoing or organised supply
Commercial quantities
Being part of a drug network
Two things that surprise people: giving drugs to a mate for free can still count as supply — and you can be charged with "deemed supply" just for being caught with more than a set amount, even with no proof you sold anything.
How a charge usually starts
Because these cases are serious, police often build them over time. A charge may follow:
Watching and listening
Surveillance and phone taps
Undercover "controlled buys"
Intercepted messages or admissions
What they look for
Drugs, packaging or cash found in a search
Parcels stopped at the airport or in the post
Amounts over a threshold (treated as supply)
Depending on the scale, these charges can be laid under state law or Commonwealth (federal) law.
What happens at court
Serious supply and trafficking matters end up in the higher courts. The path usually looks like this:
First appearance — the matter starts in the magistrates' court.
Committal — a hearing that decides whether it goes up to a higher court.
Higher court — a trial, or a guilty plea, in the District, County or Supreme Court.
Sentencing — the prosecution has to prove you intended to supply, or were trafficking.
With strong representation, charges can sometimes be downgraded to possession or withdrawn — which is why early legal advice matters most here.

Penalties where you are
New South Wales
NSW
Most serious cases — top of the scale
Up to 20 years in jail
Plus fines up to $385,000, and life imprisonment for large commercial quantities.
Read this as a ceiling, not a forecast. These top figures — including life — are aimed at large, commercial and organised operations. Low-level supply, like sharing a small amount, sits well below them, though it can still mean a record and prison time.
What it covers

Common defences
Every case turns on its own facts, but these are the kinds of arguments a lawyer might use:
No intent to supply
The drugs were for your own personal use, not to pass on.
The search was unlawful
Police breached the rules of a warrant or their powers.
It wasn't yours
The drugs belonged to someone else, or weren't in your control.
You were forced
You acted under threat or pressure from someone else.
