Step 1: The Roadside Breath Test
Queensland Police conduct Random Breath Testing (RBT) operations across the Cairns region — on the Captain Cook Highway, the Bruce Highway south of Gordonvale, the Esplanade, and on arterial roads throughout the northern beaches and western suburbs. RBT can also occur at fixed checkpoints on major event nights and weekends.
If you are pulled over at an RBT or stopped for any traffic matter, the officer may require you to provide a preliminary breath test. This is a handheld device that gives an indicative reading — positive, negative, or inconclusive. It is not the reading used in court.
If the preliminary test is positive, the officer will:
- Advise you that you are required to accompany them to the police station (or a mobile testing unit) for a formal breath analysis
- Caution you that failure to provide a specimen is an offence
- Transport you to the station (your vehicle will be left at the roadside or impounded depending on the circumstances)
You are not under arrest at this point — you are required to accompany the officer for the formal test. However, you are not free to leave, and attempting to do so may result in a charge of obstructing police.
Step 2: The Station Breath Analysis
At the police station, a formal breath analysis is conducted on a Draeger Alcotest 9510 (or equivalent approved device). This is the reading that matters — it is the reading the prosecution will rely on in court. The process involves:
- A 20-minute observation period during which the operator ensures you do not consume anything, vomit, or do anything that could affect the accuracy of the reading
- Two breath samples — you breathe into the machine twice, and the lower of the two readings is used (the reading more favourable to you)
- The machine produces a certificate of analysis — a printed document recording the reading, the time, the machine serial number, and the operator's details
The certificate of analysis is the prosecution's primary evidence. Your lawyer will review the certificate and the prosecution brief to confirm the procedure was followed correctly before advising on plea.
You will be given a copy of the certificate. Keep this document — it is the first thing your lawyer will need to see.
Step 3: Licence Suspension and Notice to Appear
If the reading is above the legal limit, two things happen immediately:
Immediate Licence Suspension
Your licence is suspended immediately. The type of suspension depends on the reading:
- Low range (0.050–0.099) — 24-hour suspension. After 24 hours, you can drive until the court date.
- BAC of 0.100 and above — your licence is suspended immediately and remains suspended until the matter is dealt with at court. You cannot drive at all — for any purpose — until the case is finalised. This applies to all readings of 0.10 and above, whether mid range or high range.
The immediate suspension is separate from the disqualification period imposed at sentencing. The time spent under immediate suspension is not credited against the disqualification period — they run consecutively.
Notice to Appear (NTA)
You will be served with a Notice to Appear — a document that specifies the charge, the date of the court hearing, and the location of the court (Cairns Magistrates Court, Spence Street, Cairns). The court date is typically four to six weeks after the offence date. You are required to attend on that date or have a lawyer appear on your behalf.
Step 4: The Preparation Window
The period between the charge date and the court date — typically four to six weeks — is the preparation window. What you do during this period directly affects the sentencing outcome. The magistrate will sentence you based on the material before them, and the material you prepare during this window is the material that shapes the outcome.
Engage a Lawyer
Contact a criminal defence lawyer as soon as possible after the charge. The lawyer will:
- Obtain and review the prosecution brief (the QP9 and supporting documents)
- Check the evidence and advise on plea
- Advise on the likely sentencing range for your specific reading and circumstances
- Guide your preparation — what references to obtain, whether to do QTOP, whether a work licence application is appropriate
Character References
Obtain two to four references from people who can speak to your character, your employment, and the impact of a licence disqualification on your life. The best references are from:
- Your employer — confirming your position, how long you have been employed, and whether you need your licence for work
- A community member who has known you for a significant period
- A family member who can speak to your responsibilities (children, elderly parents, medical appointments)
QTOP — Queensland Traffic Offender Program
If time permits before the court date, completing the Queensland Traffic Offender Program is one of the most effective sentencing strategies. QTOP is a group-based program that addresses the factors behind traffic offending. Completion is viewed very favourably by magistrates in the Cairns Magistrates Court and typically results in a shorter disqualification period within the available range.
Alcohol Assessment or Counselling
Arranging a session with a counsellor or your GP to discuss the offence and obtain a report is evidence of taking the charge seriously. It does not mean you are admitting to an alcohol problem — it means you are demonstrating insight and accountability. The report should confirm the assessment and any recommendations.
Step 5: The Court Hearing
On the court date, you attend the Cairns Magistrates Court on Spence Street. If you have a lawyer, the lawyer will typically ask you to attend at least 30 minutes before the listed time to review the material one final time.
The Plea
When your matter is called, the charge is read and you (or your lawyer) enters a plea — guilty or not guilty. For the majority of drink driving charges, the plea is guilty, and the focus is entirely on sentencing.
The Prosecution Summary
The prosecutor reads a summary of the facts — the circumstances of the stop, the BAC reading, and any relevant prior history. This is the prosecution's version of events and is typically brief.
Defence Submissions
Your lawyer then addresses the magistrate on sentencing. The submissions cover:
- Your personal circumstances — age, employment, family responsibilities, community ties
- Your traffic history — particularly the absence of prior drink driving offences
- The mitigating material — character references, QTOP completion, alcohol assessment, and any other preparation
- The appropriate disqualification period — within the statutory range, with reasons for why the lower end is appropriate
- Whether a work licence should be granted (if eligible and an application has been prepared)
The Sentence
The magistrate imposes the sentence. The components are:
- Disqualification period — the period you cannot hold a driver's licence
- Fine — the monetary penalty
- Conviction — whether a conviction is recorded (for very minor first offences, the magistrate may choose not to record a conviction)
- Interlock condition — whether an alcohol interlock device is required on relicensing
- Work licence — if applied for and granted, the work licence conditions
After the Hearing — What Happens Next
The disqualification period begins immediately from the date of sentencing. During the disqualification period, you cannot drive — driving while disqualified is a separate, more serious criminal offence. At the end of the disqualification period, you must reapply for your licence at the Department of Transport and Main Roads. If an interlock condition was imposed, the interlock device must be installed before you can drive.
