There have been chaotic scenes along the Nullabor at the WA border as travel restrictions come into effect in (at the time of publish) just a couple of hours.

From 1.30pm WA time, anyone arriving in WA will be required to self-isolate for 14 days.

There will be exemptions for health, emergency, defence and policing personnel, certain mining industry workers, flight crews and those delivering essential goods via ports and trucks.

Exemptions will also be granted on compassionate grounds and where people live near border communities.
