“I feel like I’m playing at the same level, if not better, at the moment,” Bolt said.
“I’m confident that I can crack the top 100 at some point next year.
“I just need to get my level to a place where I can consistently play big-game tennis day in and day out and I think the results will come.”
Bolt received treatment for a sore glute in the second set, but is confident the issue won’t hinder him when he faces No.3 seed Max Purcell in a semi-final on Friday.
Purcell defeated Tasmanian Harry Bourchier in straight sets 7-6 (7-4), 6-3, 6-1 to advance.
On the other side of the draw, Queensland’s John-Patrick Smith was the first player through to the semis.
The 30-year-old defeated Aleksandar Vukic 6-3, 6-7 (13-15), 6-3, 6-1 in just over three hours in a quarter-final played in cool, gusty conditions on court 8.
“They were tricky conditions with a bit of cloud and swirling wind out there, but I stayed pretty focused and took care of business, which is great,” Smith said.
“I was a little unlucky in the second set, but I just found my groove a bit there in the third and fourth and it worked out well.
“I don’t want to think too far ahead, I just want to relax and have a bit of fun … I’m getting old now so I want to treasure every match I play.”
Smith will play No.8 seed Maverick Banes, who came from two sets to one down to defeat wildcard Tristan Schoolkate 4-6, 6-0, 4-6, 7-5, 7-5.
