Constructed by the German Democratic Republic (GDR, East Germany), starting on 13 August 1961, the Wall cut off (by land) West Berlin from virtually all of surrounding East Germany and East Berlin until government officials opened it in November 1989. Its demolition officially began on 13 June 1990 and finished in 1992. The barrier included guard towers placed along large concrete walls, accompanied by a wide area (later known as the ``death strip'') that contained anti-vehicle trenches, ``fakir beds'' and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the ``will of the people'' in building a socialist state in East Germany.

It trades in the world foreign exchange markets behind the US dollar, the euro, the yen and the pound sterling. The Australian dollar is popular with currency traders, because of the comparatively high interest rates in Australia, the relative freedom of the foreign exchange market from government intervention, the general stability of Australia's economy and political system, and the prevailing view that the Australian dollar offers diversification benefits in a portfolio containing the major world currencies, especially because of its greater exposure to Asian economies and the commodities cycle. The currency is commonly referred to by foreign-exchange traders as the ``Aussie dollar''.
