Top Australian and US trade negotiators have all but run out of time to seal a free trade pact, which is threatened by a row over access to US markets.
Australian Trade Minister Mark Vaile and US Trade Representative Robert Zoellick locked horns all day Friday in search of a last-minute deal.
"Negotiations are continuing. We are working hard to complete the free trade agreement," said Richard Mills, Mr Zoellick's spokesman.
An Australian official said: "They are still talking."
The talks hit a sticky patch after the United States dug in its heels over access to its heavily-protected sugar market.
Australia is also understood to be seeking access to the US dairy and beef sectors.
Australia has warned that there must be agreement on all areas for a deal to succeed.
But a congressional source familiar with the talks suggests both sides may be working on a face saving formula, with the US perhaps offering concessions in other markets.
