In Western Australia it is maybe easier to say where you CAN smoke rather than where you Can't.
You Can Smoke more than 5 metres away from the entrance to a building (unless it is on a "Smoke free Campus" of which there are more each week.

You can smoke in your car (As long as there are no children inside)
You can smoke in the designated area of a Beer Garden of a Tavern.
You can smoke in the Designated areas of the Casino (all outside apart from the International Gamblers Lounge)

You can't smoke on the beach,
You can't smoke in the Park

WA is pushing to be the first Australian State to be completely SMOKE FREE.

As an ex smoker, I understand how hard it is when you are treated like an outcast when you smoke. However I welcome the move with open arms.

Cheers
