Johnny Lewis has seen enough in just six professional fights to declare Justis Huni "one of the best heavyweights we've ever had".
The Brisbane talent (6-0) will fight New Zealand's Kiki Leutele (8-1-2) at his home city's Nissan Arena next Friday.
If all goes to plan, his management expect the 23-year-old to be in world title contention within 18 months.
A trainer to six world champions - including Jeff Fenech and Kostya Tszyu - Lewis has seen enough to suggest those ambitions are not misplaced.
"He's been moved along well and things are happening for him," Lewis told AAP.
"Time will tell but he's still only young and certainly one of the best we've ever had in the heavyweights."
Australia has been blessed with an array of boxing talent in the lighter divisions but it is a different story at the heavier end of the scales.
Alex Leapai's 2014 title fight against Wladimir Klitschko ended a 106-year wait for an Australian heavyweight challenger, while Lucas Browne won the WBA title in 2016.
A standout amateur, Huni is known for his fast feet and hands, as well as his technical prowess.
Power, or a perceived lack of it, has been a constant narrative Huni has laughed off, even though he spent a large chunk of his recent US training camp with Justin Fortune working to improve it.
Leutele's trainer Isaac Peach told AAP Huni was the "most boring guy in Australian boxing" and that his charge will be the Queenslander's "first real fight".
Noting similarities to Ukrainian boxer Oleksandr Usyk, champion in four of five heavyweight divisions, Lewis said Huni should be wary of changing much.
"He's won them all; if it ain't broke don't fix it," Lewis said.
"If he's not going to be a puncher, just let his skill take over.
"When you're a big bloke like that, start punching quickly to the head.
"It might take four (punches) to be like one Mike Tyson upper-cut but his speed and boxing skills will enable him to get those shots away.
"He's going to go alright, no doubt about that, he's a good boy."
