Too often you talk absolute rubbish. Do you know that Western Australia accounts for over 40% of Australia's export value and that it receives 35c back from GST distribution for every dollar it collects.
W.A. subsidises South Aust., Tasmania and the Northern Territory to the tune of $1.35, $1.50 and $5.00 approx respectively.
The adjustments in the past in WA's favour were miniscule in comparison, so it is not only the engineroom of this country but pays for the privelege.
