Nov 1 (Reuters) -Australian shares declined 1% on Friday, with broad losses across most sectors, as investors weighed in the implications of the outcome of the U.S. presidential election as well as central bank monetary policy decisions next week.

The S&P/ASX 200 index .AXJO retreated 1% to 8,082.6 points by 2325 GMT. The benchmark declined more than 1% in October.

Global investors are wary of the U.S. election outcome on Tuesday, with opinion polls suggesting Republican candidate and former U.S. President Donald Trump and Democratic candidate and Vice President Kamala Harris are neck and neck in the highly anticipated race to the White House.

Interest rate decisions from the U.S. Federal Reserve and the Reserve Bank of Australia are also due next week.

The Federal Reserve is widely expected to cut interest rates by 25 basis points, while the RBA is expected to keep its policy rates steady.
