Driving Whilst Intoxicated (DWI) Penalties in Australia

Drink driving, driving whilst intoxicated (DWI) and driving under the influence (DUI) generally refer to the same offence. This being that a person has enough alcohol in their system to affect their driving.

The consequence of DWI offences range significantly across Australia’s states and territories, and it is important to know the difference.


In Queensland there are four alcohol limits that affect the penalty determination. These include:

  • 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 are governed by the Transport Operations (Road Use Management) Act 1995.

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 DWI 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.

New South Wales

In New South Wales there are five categories for drink driving offences. These include:

  • The novice range (0.00 to 0.019);
  • The special range (0.02 to 0.049);
  • Low range (0.05 to 0.079);
  • Mid range (0.08 to 0.149); and
  • High range (0.15 and higher).

A different penalty and suspension period applies for each range. Penalties are also increased if you have been convicted of another major offence within five years of the drink driving charge.

  3. Level 3 (prescribed concentration of alcohol of between 0.08 and 0.149); and
