Fergal O’Brien and Ken Doherty suffered defeats in the round of 16 at the Australian Goldfields Open.

O’Brien went down by 5-2 in his match with Dominic Dale.

Doherty also lost out on a similar scoreline to Marco Fu. The latter rattled off the first three frames with a highest score of 60 before the Dubliner narrowed the deficit with a 116 break.

However, Fu responded in kind with a century break of his own before sealing victory in the seventh frame.

Elsewhere, Neil Robertson reached the quarter-finals of his home tournament for the first time. He lost the first frame against Jamie Cope, but went on to win four of the next five, which included breaks of 82, 83 and 91.

The left-handed cueist then sealed victory in the eighth frame courtesy of a break of 68.

Paul Davison failed to seize his opportunity against Mark Davis after being edged out 5-4 in a match that lasted over four hours.

Davison led 4-3 and was 60-20 ahead in the eighth frame but Davis recovered to level before again coming from behind in the decider to nick it.

Breaks of 85, 112 and 75 helped Robert Milkins secure a 5-3 success over Ben Woollaston, while Ding Junhui advanced after a walkover victory over Rory McLeod.
