Queensland drivers caught using their mobile phones will cop a whopping $1000 fine while repeat offenders will face double demerit points.

Under new laws, in effect this Saturday, motorists caught using mobile phones while driving will be fined $1000 and receive four demerit points.

Drivers who are caught twice in 12 months will face double demerit points and a further $1000 fine.

New mobile-phone detecting cameras, which are already used in New South Wales, will be trialed later this year in Queensland.
