Western Australia
Just like New South Wales, Western Australia has very strict enforcement of double demerit points. In fact, their double demerit Christmas period is even longer than that of New South Wales, stretching all the way from the 21stof December to the 6thof January.
They penalise each of the same traffic offences as New South Wales do, also placing a further emphasis on drink or drug driving.
Australian Capital Territory
Law enforcers in the ACT very strongly follow the lead set by their NSW counterparts, enforcing double demerits for the same period of time. These double demerits will also be enforced on the exact same offences as NSW, with the intention of reducing the Christmas road toll.
Queensland
Unlike many of the other states and territories, Queensland double demerit points are not just limited to holiday periods. Drivers who repeatedly commit certain offences will always incur double demerit points if the later offence was committed within 12 months.
In a double whammy for Queensland licence holders, these rules will apply regardless of where your traffic offence occurs, even if this is outside Queensland. This further reduces your margin for error and puts you at greater risk of having your licence suspended.
