In the past three weeks more than 300 drivers crossing into South Australia from Victoria have been slapped with on-the-spot $375 fines for attempting to bring fruit and vegetables into this state.

Last month, 232 drivers received fines at a random roadblock near Bordertown, while at the weekend another 60 people were fined at Yamba Quarantine Station just outside of Renmark. The crackdown is part of the state government’s new zero tolerance approach in the fight against fruit fly, following a recent outbreak of Queensland fruit fly in Loxton.

It also follows the discovery of more than 500 kilograms of fruit in 285 vehicles at Yamba across a weekend in mid-December.
