Australian Open: Neil Robertson through to quarter-finals
World number one Neil Robertson advanced to the quarter-finals of the Australian Open for the first time with a 5-3 win over Jamie Cope.
Robertson, 31, had never previously progressed beyond the last 16 in two attempts but hit three breaks over 80 to ease past the world number 40.
The Australian will play either Stuart Bingham or Joe Perry in the next round.
Elsewhere, Dominic Dale moved into the last eight with a 5-2 victory over Fergal O'Brien.
The 41-year-old Englishman will play either Shaun Murphy or Marco Fu.
Playing on home soil, Robertson got off to a bad start when he lost the first frame, but rattled off four of the next five with big breaks of 82, 83 and 91 to lead 4-2.
Cope snuck the next on the black to close to within a frame, but a break of 68 was enough to see Robertson progress.
"It was a good performance and hopefully by the time the quarter-finals start I will be back to 100% health," Robertson, who has been suffering with a cold, told World Snooker's website.
"Jamie played well so I was very pleased to get the match finished. When he won the seventh frame I did fear losing in the last 16 again. I scored heavily and on another day I might have had three or four centuries."
Elsewhere, Mark Davis edged past Paul Davison 5-4 while Robert Milkins beat Ben Woollaston 5-3. Ding Junhui also progressed after a walkover victory over Rory McLeod.
