Jeff Horn will be ready to adapt to whatever happens in Sunday's 'Battle of Brisbane', trainer Glenn Rushton says.

A crowd of more than 50,000 will be on hand for the unbeaten Australian's title shot against Manny Pacquiao for the WBO welterweight crown.

Pacquiao is the hot favourite but Horn's camp is confident he can produce an upset over the Filipino legend, who is out to prove he is still at the peak of his powers at 38.

Horn may not be as quick as Pacquiao but he is bigger, younger and, according to Rushton, perfectly prepared for whatever sort of fight comes his way.

"We'll work the entire target area. If people think he's just going to throw the right hand and try to land like Jessie (Vargas) did, ain't gonna happen," Rushton said.

"Jeff can KO with any punch. We don't need a KO but we want it. We can work head, we can work body, long range, close range, mid range. He's a very all-round fighter. We're not a one-trick pony."

The bout is set to begin at 1.30pm AEST after a six-fight undercard.

Highly-rated Canberra boxer David Toussaint will take on Shane Mosley Jr in the first televised fixture while Ireland's Michael Conlan - who is helping UFC star Conor McGregor prepare for his clash with Floyd Mayweather Jr - is scheduled for his third professional bout against Queenslander Jarrett Owen.
