Morrison needs to dump the Crown, page-23

Perth can get stuffed, they [WA] look likely to secede soon anyway and won't let us Australians near the joint so we should just ignore them and build a big wall to keep them out and make them pay for it by deducting its cost from GST share.

I wish !
There was a secession movement in the 1930's but too hard to untie the knot .
But you mentioned GST , a bit of a sore point over here .
This is dated , we now get 70c in the $ but check this out :

GST return by state (FY2017–18)^[7]

State/territory	GST return
Western Australia	0.34434
Australian Capital Territory	1.19496
New South Wales	0.87672
Northern Territory	4.66024
Queensland	1.18769
South Australia	1.43997
Tasmania	1.80477
Victoria	0.93239

We had a lot of debt at the time with all other states bleeding us and infrastructure still needed to be built for those mines .
