Newly crowned IBF, WBA, WBC Franchise, WBO lightweight champion George Kambosos arrived back to Australia - and received a hero's welcome with over 200 fans to greet him at the Sydney International Airport.

Last month, Kambosos became the unified champion when he upset the odds by dropping and decisioning heavily favored Teofimo Lopez over twelve rounds at the Hulu Threater at Madison Square Garden in New York.

"As much as I had to go do it inside the ropes, my family and my friends and both my countries lifted me, especially in that round 10," Kambosos said to Fox Sports AU.

"It's a big moment for everyone that's been around me, a big moment for Australia. This is huge. I had to go and really earn it. I had to go to the backyard [of my opponents] multiple times and to go and beat this guy in his prime and in his home town, no Australian fighter's ever done that before. So these belts mean a lot and they mean a lot to the whole of our country."

Kambosos wants to defend his belts on a date in April or May in a stadium in Sydney or Melbourne.

Some of the opponents on his radar - WBC champion Devin Haney, unbeaten Ryan Garcia, WBA "regular" champion Gervonta Davis and three division champion Vasilily Lomachenko.

Whoever he ends up facing, Kambosos wants the contest on home soil.

Haney has already made it clear that he's willing to travel over to Australia to face Kambosos.

"We're bringing the big fights here now. I deserve it, I've earned that," Kambosos said.

"I haven't fought here since 2017 so a big fight (is coming) and we're going to bring that to a massive stadium - 80,000 people. Haney, Davis, Lomachenko, Garcia, they're all going to get it."
