Aussie hopes were hit with bad weather and bad results on day one of the Australian Open in Melbourne.

All four local players who took to the court on Sunday lost their matches to be bundled out of their home grand slam.

Li Tu, Daria Saville, Osama Jasika, and Adam Walton are all out of the Open.

Wildcard Tu fought bravely against No.24 seed Jiri Lehecka but fell in four sets, as did Osaka against Hugo Gaston despite the Frenchman battling a raucous Court 3 crowd that was heavily in favour of the Aussie.

Walton was well on top of Quentin Halys, taking the first two sets 6-4.

But he then fell to an epic comeback from his opponent who took the next three sets 6-4, 7-6(4), 7-5 to clinch the match and knock Walton out.

Saville, in the Open thanks to a wildcard, dominated to win her first set 6-1 against Anna Blinkova but also lost a thriller in three sets.

The Aussie only won three from 15 possible break points. Blinkova won three from eight.

There are plenty of Aussie hopes still alive in round one.
