How drink driving penalties work

Across Australia, courts consider your BAC range, whether it is a first or repeat offence, your licence class (e.g., learner/provisional/zero‑BAC), and aggravating features (collisions, refusal, drugs). Most states have mandatory alcohol interlock programs for mid and high ranges or repeat offences.

General information only: Figures below are indicative court ranges sourced from government pages and legislation. They can change. Always verify using the official links and obtain legal advice for your situation.

Drink driving costs and interlock fees by state

Beyond fines and licence loss, most drivers face interlock device costs, court fees/levies and insurance/employment impacts.

Typical interlock program costs

Other common expenses

  • Court fees/levies: typically $100–$300+ depending on jurisdiction and outcome
  • Legal representation: fixed fees for pleas commonly $800–$2,500+, more if contested
  • Course/treatment: drink‑driver education programs often $200–$900
  • Licence reissue and interlock condition fees apply at the end of disqualification

Concessions and hardship programs may reduce interlock costs. Ask our team to check eligibility in your state.

What affects drink driving sentencing

  • BAC range and number of prior drink/drug driving offences
  • Collision, injury, speed or dangerous driving aggravations
  • Licence class (learner/provisional/zero‑BAC categories)
  • Early plea, cooperation, remorse, rehabilitation steps (courses, counselling)
  • Work and family hardship evidence (for disqualification length)
  • Completion of alcohol education or assessment prior to court

Drink driving FAQ

Is refusing a breath test worse than a high BAC?

In most states, refusing or failing a breath/blood test attracts penalties comparable to high‑range drink driving, with mandatory interlock and longer disqualification. See NSW, QLD, SA, WA and ACT links above.

Will I get a criminal record?

Drink driving is a criminal offence in every state. A conviction may appear on your criminal/traffic history and can affect travel, employment and insurance. Courts can, in limited cases, record no conviction while still imposing penalties.

Can I drive to work on a restricted licence?

Work licences are available only in limited jurisdictions (e.g., QLD in specific conditions). Other states generally do not offer conditional work licences for drink driving, but interlock programs can return limited driving sooner.

How do interlock orders work?

Courts or transport authorities impose an alcohol interlock condition for a set period after disqualification. You pay for installation, monthly calibration and removal; violations can extend the period. Duration depends on BAC and prior offences.

What should I bring to court?

Bring your charge sheet, police facts, character references, proof of course/enrolment, employment impact letters, medical records (if relevant), and a short apology statement. A lawyer can tailor materials to your magistrate and jurisdiction.
