South Australia, Tasmania, Victoria and the Northern Territory do not have double demerits for holiday periods, or any time of the year.
Here’s what you need to know.
New South Wales
Double demerits in NSW began on Thursday and will be in effect until Monday, ending at 11.59pm on Sunday January 28.
Anyone caught speeding, using their mobile phone, not wearing a seatbelt or a helmet will face double the penalty.
Offenders snapped on speed and mobile phone detection cameras will also lose double the points.
However, anyone caught breaking the rules won’t have to pay double the fine.
Queensland
Queensland is the only place in the country where double demerit point apply all year round, not just during holiday periods.
People who commit specific offences repeatedly will receive double demerit points for the second or subsequent offence, if the later offence was committed within 12 months of an earlier offence.
Offences you can cop double demerits for include speeding more than 20km/h over the limit, using a mobile phone, not wearing a seatbelt, failing to ensure passengers under 16 are appropriately restrained and not wearing a helmet when riding a motorcycle.
Western Australia
Double demerits in Western Australia apply over the Australia Day long weekend, starting on Thursday.
Like NSW, they will be in effect until, and including, Sunday, January 28.
Speeding, drink or drug driving, failing to wear a seatbelt and child restraint, running a red light and illegal use of a mobile phone while driving are some of the offences drivers are warned against this long weekend, and will all incur double demerits points.
There are two offences that could cost offenders a whopping 14 points during the double demerits period: driving a motor vehicle fitted with a device designed to evade detection by a speed camera and driving a motor vehicle in a manner to evade detection by a speed camera.
