The Australian stock market has fallen with broad-based declines as investors offload securities in response to a weak global economic outlook.

On a positive note, Australia's big resources companies were higher.
BHP was up six cents at $33.53, Rio was four cents firmer at $55.74 and Woodside had climbed 22 cents to $33.80.
Bell Potter senior adviser Stuart Smith said there was a shift towards these big resources companies as the local market consolidated recent gains.
"There is a switch from the conservative ends of the market, which is your banks and retail and Telstra and that sort of thing, into resources," Mr Smith said.
"That's the not-so-subtle change that is happening and it is overdue and, I think, it is positive."
