Being caught using a mobile phone while driving in Queensland is about to get a lot more expensive.

The Queensland Government has announced any driver caught using a mobile phone behind the wheel will be fined $1000 and four demerit points.

For drivers caught twice within 12 months, double demerit points apply and they may now lose their licence.

Queensland will also trial cameras recently introduced in New South Wales to detect mobile phone usage.

The new laws come into effect on February 1, 2020.
