Covert cameras that bust motorists using their mobile phones behind the wheel are set to begin dishing out $1000 fines to drivers from October.
New figures have revealed the cameras caught out more than 15,000 potential mobile phone offences during a six-month trial that wrapped up in December.
It means the Government could have raked in over $15 million if fines had actually been issued.
The technology also detected more than 2200 potential seatbelt offences, including passengers sitting in the front seat of the vehicle.
The government has revealed the cameras will be rolled out again on Queensland roads from the second half of the year, but there will be a three-month grace period where motorists will only get warnings.
