Given that the Keynesian International Monetary Fund in an influential internal report is making plans for the introduction of a global currency, anticipating the imminent demise of the U.S. dollar, can we expect the labor party, whose economic policy platforms are vehemently Keynesian, to be solid supporters of am IMF directive for the exchange of the Australian currency system in favour of the global coinage? No doubt “in the best interests of Australia going forward.”  
There is every reason for Australian debt, especially government deficits to be reigned in very quickly in view of the momentous changes that seem quite likely to take place on the world economic stage in the near future.

Given Australia's relative national wealth to population ratio amid a world that is general economic decline at present, this country will come under extreme pressure by globalising "authorities" such as  the IMF to contribute to the "common wealth" of an international currency structure. Will we have a government which agrees wholeheartedly with the global demands, or will we have a government which defends Australian national economic integrity and retains our independence in the face of such demands to conform?

Excellent idea! I doubt the US or English would like it though. They'd prefer the currency was in dollars or pounds.

Isn't gold already a global currency?

the world reserve currency is presently, so far, the U.S. dollar. The U.S. dollar was decoupled from the gold standard by the Nixon Administration in the U.S.
Australia followed suit under the Keating Government.
This results in floating currencies and speculation, and it is a very convenient way for governments to spend up huge deficits without the restraint that the requirement for currency to be backed by (finite) gold reserves requires.
A global currency will be controlled by *someone*, but it will not be the U.S. or the U.K. In any event they are in decline, and the U.S. dollar is in real prospect of collapse, not just as the global reserve currency, but as an internal currency in the U.S.
Gold is not yet a global currency, it is a tradeable commodity, it is not legal tender in other than a handful of countries, generally the Islamic ones. So far.
If there is a global currency brought in in the interests of global economic stability, there will be a trade-off in national sovereignty issues. Will labor comply, or stand for Australia's independence from the new world order?
