Drug Supply on an Ongoing Basis: Expert Criminal Defence
Supplying prohibited drugs on an ongoing basis represents one of the most serious drug offences in Australian criminal law, carrying maximum penalties up to life imprisonment. Whether you’re facing charges for ongoing commercial drug supply, deemed supply based on quantity, or allegations of regular drug dealing over extended periods, understanding this offence’s legal elements, available defences, and severe consequences is crucial for protecting your rights and mounting an effective legal defence.
National Criminal Lawyers provides expert defence for ongoing drug supply charges throughout Australia. Our team understands these prosecutions’ complexities, the sophisticated evidence prosecutors rely upon, and the strategic defence approaches necessary when facing these extremely serious allegations.
What Is Drug Supply on an Ongoing Basis?
Drug supply on an ongoing basis offences are created by state and territory drug legislation throughout Australia. In NSW, section 25A of the Drug Misuse and Trafficking Act 1985 criminalises knowingly taking part in the supply of prohibited drugs on an ongoing basis.
The Core Offence
You commit this offence when you knowingly take part in the supply of a prohibited drug on three or more separate occasions during any 30 day period, and the supply involves not less than the traffickable quantity on each occasion.
This provision targets regular drug dealers and commercial operations by criminalising patterns of repeated supply rather than just individual supply incidents.
Traffickable Quantities
The offence requires each supply instance to involve at least traffickable quantities—threshold amounts indicating commercial dealing rather than personal use. Traffickable quantities vary by drug type:
- Cannabis: 300 grams
- MDMA/Ecstasy: 0.75 grams (3 tablets)
- Cocaine: 3 grams
- Heroin: 3 grams
- Methamphetamine/Ice: 3 grams
These thresholds mean the offence captures regular commercial dealing rather than casual sharing between users.
Commercial Quantities
When ongoing supply involves commercial quantities—substantially larger amounts indicating serious commercial operations—maximum penalties increase dramatically to life imprisonment, reflecting the grave seriousness of large scale drug trafficking.
What Prosecutors Must Prove
Understanding what prosecutors must establish beyond reasonable doubt helps you appreciate your case’s strengths and available defences.
Element 1: You Knowingly Took Part in Drug Supply
Prosecution must prove you knowingly participated in drug supply activities. “Taking part” includes actually supplying drugs to others, facilitating others’ supply activities, storing or transporting drugs for supply, acting as intermediary in supply transactions, and providing assistance enabling supply operations.
You need not be the primary supplier—participating in any meaningful way in supply operations satisfies this element.
Element 2: Supply Occurred on Three or More Occasions
Prosecution must prove at least three separate supply instances occurred during the relevant 30 day period. These must be distinct transactions, not merely multiple deliveries within single transactions.
Establishing multiple supply occasions typically requires surveillance evidence, communications showing multiple transactions, witness testimony from multiple purchasers, or admissions about repeated dealing.
Element 3: Within a 30 Day Period
All supply instances must occur within any 30 day period, though not necessarily the same 30 days charged. If prosecution proves three supplies over different overlapping 30 day periods, the element is satisfied.
Element 4: Each Supply Involved Traffickable Quantities
Prosecution must prove each supply instance involved at least traffickable quantities of prohibited drugs. If any of the three supplies involved less than traffickable amounts, the ongoing supply charge cannot succeed, though lesser charges might apply.
Element 5: You Knew About the Supply
Prosecution must prove you knew about the drug supply activities in which you participated. Genuine ignorance that substances were prohibited drugs or that supply was occurring provides defences, though such claims face scepticism when circumstances strongly suggest knowledge.
Maximum Penalties for Ongoing Drug Supply
Ongoing drug supply carries severe maximum penalties reflecting its extreme seriousness as a commercial drug trafficking offence.
Non Commercial Quantities
When ongoing supply involves traffickable but not commercial quantities, maximum penalties reach 20 years imprisonment—double the 10 year maximum for single supply offences.
Commercial Quantities
When ongoing supply involves commercial quantities on any occasion, maximum penalties increase to life imprisonment for the most serious drugs, reflecting that these matters involve serious organised crime.
Large Commercial Quantities
Ongoing supply of large commercial quantities attracts life imprisonment maximums across all serious drug categories.
Sentencing Factors
Actual sentences vary based on drug types and quantities involved, your role in supply operations (principal supplier versus assistant), whether you profited financially from supply, duration and scale of supply activities, whether organised crime involvement existed, your criminal history, and evidence of remorse and rehabilitation prospects.
Full time imprisonment is virtually inevitable for ongoing supply convictions given offending seriousness, particularly when commercial quantities are involved. Even first time offenders face substantial imprisonment terms for these serious trafficking charges.
Defences to Ongoing Drug Supply Charges
Several defences may be available depending on your case’s specific circumstances.
Defence 1: Insufficient Evidence of Three Supply Occasions
If prosecution cannot prove beyond reasonable doubt that at least three separate supply instances occurred within 30 days, the ongoing supply charge must fail. Challenging evidence about number of supplies, their timing, or whether they occurred within the required timeframe provides defence opportunities.
Defence 2: Quantities Below Traffickable Thresholds
If any alleged supply involved less than traffickable quantities, the ongoing supply charge cannot succeed. Challenging prosecution evidence about drug weights through independent testing or expert evidence creates defence opportunities.
Defence 3: Lack of Knowledge or Participation
If you didn’t know about drug supply activities or didn’t participate in them—you were unaware substances were drugs, you didn’t know supply was occurring, or your involvement was innocent—you haven’t committed the offence.
Successfully establishing this defence requires evidence supporting claimed lack of knowledge or explaining innocent reasons for actions prosecution characterises as participation.
Defence 4: Duress
In extremely limited circumstances, you might establish you participated in drug supply under duress—compelled by threats of serious harm. However, this defence faces exceptionally high evidentiary thresholds and rarely succeeds in drug supply prosecutions.
Evidence in Ongoing Supply Prosecutions
These prosecutions typically involve sophisticated evidence requiring careful analysis.
Surveillance Evidence
Police surveillance often captures multiple alleged supply transactions through physical observation, photographic or video evidence, and tracking of movements and meetings.
Communications Evidence
Telephone intercepts, text message records, encrypted messaging content, and analysis of communication patterns often provide primary evidence of ongoing supply operations.
Drug Seizures and Testing
Physical drugs seized from you, vehicles, or properties provide direct evidence of supply quantities and frequencies when combined with other evidence showing repeated transactions.
Financial Evidence
Unexplained wealth, cash transactions, and financial records inconsistent with legitimate income often corroborate allegations of profitable drug supply operations.
Related Charges
Ongoing supply prosecutions frequently involve multiple related charges including individual supply charges for specific transactions, possession charges for drugs seized, deemed supply based on quantities possessed, and proceeds of crime charges targeting profits from drug dealing.
Bail Considerations
Ongoing drug supply charges face significant bail challenges. The extreme seriousness creates presumptions against bail in many jurisdictions, requiring you to demonstrate exceptional circumstances warranting release.
Courts consider the strength of prosecution evidence, your criminal history and community ties, risks of continued drug supply if released, and whether any conditions could adequately manage risks.
Why Expert Legal Representation Is Essential
Ongoing drug supply charges represent some of the most serious criminal offences requiring the highest level of legal expertise.
Understanding Complex Drug Legislation
Drug supply laws involve complex legal frameworks regarding quantities, deemed supply, and ongoing offences. Experienced lawyers understand these intricacies and how to identify defence opportunities.
Challenging Sophisticated Evidence
Defending these charges requires analysing complex surveillance evidence, communications intercepts, and forensic drug evidence. Lawyers must work with experts who can challenge prosecution evidence effectively.
Negotiating With Prosecutors
Given charges’ seriousness, negotiation opportunities regarding specific charges laid, quantities alleged, or appropriate resolutions require skilled advocacy. Experienced lawyers can negotiate strategically with prosecutors.
Bail Applications for Serious Charges
Securing bail for ongoing supply charges requires compelling applications addressing courts’ serious concerns while demonstrating exceptional circumstances warranting release.
