Comments on Julie Bishop “Swan conjures up a Black Swan from the West”, 25/05/2011, http://www.smh.com.au/opinion/blogs/the-bishops-gambit/swan-conjures-up-a-black-swan-from-the-west-20110525-1f2y4.html
Maybe, the reactions by Swan, Gillard and Ferguson could be explained by the review of GST distribution commissioned by Gillard and Swan and announced in Perth by Gillard on 30 March 2011.
There might have been some understanding/misunderstanding or expectations (or false hopes) that that review would have WA to rethink about its scheduled increase in royalties of its fines iron ore.
The timing for that review is a draft report by February 2012 and the final report by August/September 2012 for consideration for 2013.
It is interesting to note that the final report is expected to be available after the introduction of the MRRT and the carbon tax, assuming both legislations will pass the parliament.
WA may think it will be too uncertain to rely on that review to secure a better funding for it.
Of course, the WA government is a liberal/coalition government and on the opposite political side of the Gillard ALP government.
PS: this fascinating discord involves politics, economics and taxation, as well as federal financial relations. Arguably, it is a very difficult issue even at the best of times of federal politics, not to mention the fact it is at a time the federal government has been experiencing serious difficulties.
