With the regional travel restrictions in full swing, police have been setting up checkpoints on major routes to ensure motorists are complying with the ban.
Last week on Albany Highway, Williams police blocked both lanes of traffic, waving through freight transport and local vehicles but checking other cars.
Officers took note of vehicle number plates, checked driver and passenger identification and asked for any supporting paperwork such as employment letters and exemption applications.
No vehicles were barred from crossing the border and the limited traffic was an indication that people were listening to the new rules put in place last week.
Police have the power to enforce the restrictions with fines of up to $50,000 for individuals or $250,000 for organisations, unless they can prove that they are exempt.
