Holding up his title belt and flanked by Queensland Premier Annastacia Palaszczuk, Australia's Jeff Horn brushed aside the outcry against his shock victory over Manny Pacquiao.
Horn says there will always be backlash.
"There's always naysayers saying that I didn't win the fight, but, I felt like I won the fight, I think everyone... a lot of Queenslanders think I won the fight and people around the world. So you will always have the select few that are going to be against you."
Brisbane Mayor Graham Quirk, who is also Horn's second cousin, says it's been incredible for the sport in Australia.
"That was a real slugfest. The Battle of Brisbane certainly lived up to its name. It was a real privilege for anyone attending - this will go down as one of the great fights."
Boxing promoter Bob Arum called the fight a tremendous success for Queensland and for boxing.
Horn, a 29 year-old former schoolteacher, was awarded a unanimous 12-round decision over the eight-division world champion after a bloody battle in front of more than 51,000 fans at Brisbane's Lang Park.
Arum says a rematch now depends on whether Horn would welcome it and on Pacquiao's passion to re-contest.
Boxing Analyst Paul Upham says he doesn't think Pacquiao is in the right frame of mind to be truly competitive.
"I think he's distracted by his senator duties in the Filipino parliament. At the elite level you've got to be a full-time fighter and Manny Pacquiao is not a full-time fighter. It is a part time job for him now and I don't think he can clearly focus on the job at hand of being a boxer. Manny Pacquiao has been great in the past and look he fought a good fight yesterday. It wasn't that Manny Pacquiao was bad fighter yesterday. It was just that Jeff Horn was a bit better but I just think that Pacquiao has clearly underestimated Horn. He was a nobody to him and in the end he got beaten for it."
Pacquiao, whose defeat was his first since his blockbuster clash with Floyd Mayweather Jr in 2005, indicated he would take up the option of a rematch.
Horn says he'd be delighted to face the 38 year-old in his first title defence but knows the challenge that comes with the opponent.
"Manny Pacquiao is an absolute warrior, he's a legend of this sport. He might have come in underdone, if we have a rematch, if he puts it all in he might come in better, I don't know..."
Boxing analyst Paul Upham says he believes there will definitely be a rematch.
"Pacquiao has got a contested rematch in his favour. He's not going to retire on this. I think he's going to realise that he was a both distracted, he underestimated Jeff Horn, and he's going to come back better. Jeff Horn has got to improve. If he doesn't improve, Manny Pacquiao will beat him because Pacquiao is going to be better next time."
Horn's promoter, Dean Lonergan, says he won't engage in a bidding war with other state governments to host a mooted rematch with the Filipino legend.
He says if it happens, a workable date will need to be found due to Queensland's unpredictable weather.
