The Canberra Times can reveal Horn's promoter Dean Lonergan of D&L Events is looking to bring the former world champion's next bout to Canberra on April 17 or 18.

Both Horn (20-2-1) and Tszyu's (15-0) camps have balked at fighting behind enemy lines with a neutral venue possible for what promises to be one of the biggest bouts in Australian boxing history.

Canberra Stadium would be the ideal venue should they meet in the ACT while the AIS Arena and National Convention Centre would feature in discussions if Horn meets an international opponent.

"If you're talking the Tszyu fight, it's an outdoor one," Lonergan said.

"The reason I'm looking around Australia right now is we have told Tim Tszyu our preference is to have the fight in Brisbane or at a neutral venue, that's number one.

"We're not going to fight him in Sydney, and I would definitely look at Canberra, working with [Capital Fight Show promoter] Nick Boutzos to bring a big fight down there.

"I would be fascinated because I reckon Canberra could be a great market for us long-term.

"Number two is we want to take a 60-40 split, and the second as I said that to them, they got all huffy and stopped talking to us which is pathetic when you think about what Jeff has achieved.

"He beat Manny Pacquiao in front of 51,000, defended the world title, went onto fight a future Hall of Famer in Terence Crawford, came back and destroyed Anthony Mundine who was the face of boxing, we've just been through what we have been through with Michael Zerafa.

"Jeff has had about 10 times the publicity Tim Tszyu has, and he has also achieved so much more on his boxing record as opposed to fighting Sydney club fighters."

Lonergan is determined to bring a big fight to Canberra and remains confident Horn could sell out a venue "in a heartbeat".

Former two-weight world champion Jessie Vargas tops the list of international opponents with matchmaker Stu Duncan scouring the world for Horn's next super welterweight bout.

It would open a huge year for the sport in Canberra with Lonergan's National Boxing Series, televised live on Fox Sports, coming in June.

"Whatever we do next is going to be a significant step, because we need to position Jeff to get him into world title contention, if it's not Tim Tszyu," Lonergan said.

"I say the word if because they might get over their huff and come back to open discussions.

"Jeff Horn is most certainly the A-side in the equation, and even at 60-40 it's an incredibly generous offer to a bloke who has only had 15 fights against local club guys."

Lonergan says Canberra is "definitely a market I want to build and develop" in the boxing landscape.

Former world welterweight champion Horn's arrival in Canberra would signal perhaps the biggest fight the region has seen.

Former Canberra Raiders player Lonergan is adamant the people of the capital would vote with their feet to see Horn after he surged back to prominence with a win over Michael Zerafa.

The second Zerafa bout was one of the most remarkable in recent memory after Horn avenged his defeat in Bendigo, which came in front of a full house back in August.

"Bendigo has 100,000 people, we put 4500 in a venue and sold it out. I've got no doubt we can do that in a heartbeat with Jeff Horn down in Canberra if we get the right fight down there," Lonergan said.

"Canberra is a place I like a lot, because I've got a good relationship with Nick Boutzos and it's a fairly sizeable market.

"You've got almost 400,000 people living down there, its own independent media, it's an area I definitely want to develop over the next two to three years."
