David Nyika is preparing for another battle, but this time it's a bit different, as he'll be going toe to toe with a fellow countryman on Sunday morning.
Nyika, 27, will face Titi Motusaga on the undercard of the rematch between George Kambosos and Devin Haney in Melbourne, with both fighters' unbeaten records going on the line.
With someone's '0' likely to go, the fight is high stakes, and it's one Nyika's not taking lightly.
"I've trained like a savage this camp," Nyika told Newshub. "I'm really excited to see how that affects my performance in the ring as well.
"You can be a match fit but when the occasion comes it can get to you."
The Olympic bronze medallist knows he has a target on his back - which will only grow as he develops and rises up the ranks. He's all too aware of what's on the line now every time he steps in the ring.
"I know my scalp is super valuable so he has nothing to lose except his record obviously," Nyiksa continued. "Having a clean record is massive in pro boxing.
"I think anyone watching from the outside will say he has a puncher's chance. I've trained super hard for this fight.
"I'm fit, I've been around the world, I've fought bigger, scarier guys but I haven't seen much of him for a long time."
What Nyika does know about his opponent is that he's a product of the renowned City Kickboxing set-up, home of UFC stars Israel Adesanya and Kai Kara France, as well as heavyweight boxer Junior Fa.
That in itself is reason to carry caution into the fight.
"They've got some killers out there and I know really well how they train and how they operate.
He's in really good hands and I'll be interested to see what he comes out with in the fight."
Despite this being the biggest fight of his career so far, Motusaga cuts a relaxed figure ahead of the bout.
"All I can say is just tune in," Motusaga told Newshub.
"He's looking to put on a powerful performance. If he wants to trade leather in the middle then we'll do that. If it's a boxing match it's a boxing match.
"I think he's a bit of a slow starter. He'll find his range and keep it long so I'll just have to find ways to get my work done on the inside."
As for the bright lights of Rod Laver Arena?
"It doesn't really phase me. I'm not feeling any pressure - I'm more excited about it.
"Just to walk in front of fans, it's always what I've wanted to do in front of big crowds and put on a performance."
