The Reserve Bank of Australia (RBA) announced earlier that the official "cash rate" interest rates would be kept unchanged at 1.5 percent, in a move that was anticipated by most market observers.

"It would be easier to find a golden ticket to Willy (Wonka's) Chocolate factory than an economist who thinks that we'll see a change of rate from them today, so once again the focus will be on the rate statement," Rakuten Securities said in a morning note.

Following the announcement by the RBA, the Australian dollar weakened by about 0.11 percent against the dollar to trade at $0.7203 as of 3:04 p.m. HK/SIN.
