There are a range of different drink driving offences in the different states and territories of Australia. This article sets out the offences that exist in each jurisdiction and the penalties that apply for them.


In Queensland there are four alcohol limits that affect the penalty determination for drink driving offences. These are:

  • The no alcohol limit (blood alcohol concentration of 0.00);
  • The general alcohol limit (blood alcohol concentration of 0.05 to 0.09);
  • The middle alcohol limit (blood alcohol concentration of 0.10 to 0.149); and
  • The high alcohol limit (a blood alcohol concentration of over 0.15).

The penalties for drink driving offences in Queensland are governed by the Transport Operations (Road Use Management) Act 1995.

In Queensland, a blood alcohol concentration of 0.10 and below will attract an automatic 24-hour licence suspension. Higher penalties apply for people who are tested for more than 0.10 blood alcohol concentration. All offences attract fines of increasing severity and some will have prison sentences.

For all drink driving offences, police have the power to suspend a licence until the matter is finalised in court. Read Drink Driving Penalties in Queensland for more information.
