It's amusing to read the rant from the east when it's patently obvious that you are all so intently focused on yourselves that you can't see anything other than "the West are idiots".
It is not like that at all. The East Coast realise they are part of a whole nation and we all rely on each other to keep the country working. Ultimately State Borders are only administrative however in WA it seems they believe it's a border to another country.
Anyway the party is going to end pretty quickly in WA when they run out of workers to actually do anything from cooking a steak, to engineering a road or a building. Always has been a Boom/Bust economy that has relied on staff from overseas and interstate. If it's too hard to actually get there and work then noone is going to do it. McGowan has painted himself into a policy corner. Do you either change your border policy that got you elected and look like a hypocrite or do you keep your border policy and blowup your economy??
