"Frank's a good dude, I respect him a lot," Hunt said. "I was going to shoot an uppercut through there but I thought he was a bit slower so I thought I'd catch him early with a straight right and that was what ended the fight."
Hunt, ranked ninth in the heavyweight division, asked for a top-five contender next given he has met, and lost to, the likes of champion Fabricio Werdum (20-5-1), Stipe Miocic (14-2) and Junior dos Santos (17-4).
"I can rematch these guys, I've never lost a rematch," Hunt said.
As it happened: Hunt v Mir
Many of the top fighters, including the aforementioned trio, are booked in the near future but if anyone was to be injured, Hunt could step in given he likely came through the win over Mir without any ailments. He also pocketed a US$50,000 'Performance of the Night' bonus for his win over Mir.
Meanwhile, James Te Huna's MMA career may be nearing the end after he suffered his fourth straight loss when he was knocked out in the first round by Canadian Steve Bosse (11-2).
Te Huna (16-9) was making a return to the cage after last fighting in June, 2014 but it didn't last long as Bosse's clean right hand finished the fight at the 52-second mark.
Four straight losses in the UFC usually spells the end to one's contract and it capped another disappointing trip to Brisbane for the Sydney-based Te Huna.
Watch: Kiwi UFC fighter KO'd within a minute
The 34-year-old's previous UFC appearance in Brisbane resulted in him suffering a first-round knockout loss to Mauricio Rua (23-10) at UFC Fight Night 33 in December, 2013.
Auckland's Dan Hooker got the Kiwi fighters off to a good start on the undercard when he made short work of Mark Eddiva (6-3) of the Philippines as he won via guillotine choke in the opening frame.
Hooker, who had alternated wins and losses during his first four UFC appearances, was confident of victory heading in to the bout and he backed it up emphatically.
"Mentally, you prepare for a hard fight, but it came out pretty much how I expected," said Hooker, who moved to 13-6, said after the fight. "I thought it would be a quick night. I said before the fight that I would be surprised if he made it out of the first round. That's just the way the fight turned out."
With no clear opponent for the future, the featherweight said he would take on whoever the promotion put in front of him.
"That's up to the UFC. I don't say no to anything."
At the post-fight press conference, Tom Wright, the UFC's director of operations for Canada, Australia and New Zealand, said Australia would host another card this year but he couldn't confirm the location.
