Tszyu, whose legendary father Kostya reigned as undisputed super-lightweight champion, has forged an impressive career of his own since turning professional in 2016.
Amassing a 22-0 record which includes wins over former world champions in Jeff Horn and Tony Harrison, Tszyu has worked his way into title contention.
His opponent on the Gold Coast, Ocampo boasts an impressive 35-2 professional record, having only suffered defeats to Errol Spence, at welterweight, and Sebastian Fundora.
Can Ocampo spoil Tszyu's world championship plans or will the Aussie's winning run continue?

Tszyu said he could begin sparring now, two and a half weeks out from the fight, but doesn’t want to “rip anything open”.
“I’ve tried to take it a bit easier with the punching, but I’ll be sparring my last week next week, so I’ll be back into it.
“I haven’t told many people but I’ve dealt with a lot of injuries in my career.
“I had a broken hand leading up to my first fight in my first year - I should’ve pulled out but I didn’t. Leading up to Charlo I had a torn shoulder; I didn’t say nothing, I just kept going along with it and got on with it.
“It is what it is, when you’re dealt with circumstances you’ve got to just deal with it and find a way.”
'I wish him a speedy recovery because I hope it's not an excuse on Sunday June 18,' Ocampo said in a promoter statement on Thursday.
'I won't aim for your arm because I'm a gentleman. But remember, protect yourself at all times.
'I took the fight against Tim Tszyu because he represents an important challenge in my career.
'He is the one who holds the title today, and he will understand what it is to meet a Mexican.
'I will beat Tim Tsyzyu, make no mistake.'
Ocampo has only been beaten twice in a 37-fight professional career, his 12-streak win record ended last October by WBC interim champion Sebastian Fundora by unanimous decision after 12 tough rounds.
The only other loss of his career also came in a world-title fight, against the current unified welterweight champion Errol Spence Jr back in 2016.
Ocampo said he had prepared well for the challenge of facing interim WBO super-welterweight champion Tszyu (22-0).
'This has been the best preparation of my career,' he said.
'The sparring was better than that of many world champions and my work won't be in vain, even though I have to go to the other side of the world.
'I truly believe I will beat Tim in the most unexpected way.
'Us Mexicans are different. We are distinguished fighters, we are real, we come to fight.'
