WELLINGTON, Aug 1 (Reuters) - The Australian dollar sank to a three-year low against the U.S. dollar and suffered broad losses on Thursday as investors continued to dump the currency on growing speculation that the Reserve Bank of Australia may cut interest rates next week.

The Aussie fell as low as $0.8910 according to Reuters data, its weakest since August 2010.

It also plumbed a three-year low versus the euro, which rose to around A$1.4898, while it fell to its weakest since late 2008 against the New Zealand dollar.
