Daniel Geale may get the chance to justify promoter Gary Shaw's assertion he is the world's best middleweight boxer, by taking part in a proposed box-off between the division's finest fighters.

American Shaw, who helps out the Geale camp, said cable television network HBO was trying to invest in the middleweight division.

HBO had already featured Golovkin and Sergio Martinez and Julio Cesar Chavez Jr, the latter pair meeting in a WBC middleweight world title bout last month.

"A 160-pound (middleweight) box-off, we come up with the best 160-pound fighter in the world, which I believe is Daniel Geale," Shaw told AAP.

"I believe he beats Chavez, I believe he beats Sergio Martinez."

Geale has a myriad of options following last month's unification title win over Felix Sturm in Germany.

Both Sturm and fellow German Sebastian Sylvester, who lost the IBF title to Geale last year, want a rematch with the Australian.

There is also the option of an early 2013 rematch with Anthony Mundine, the only professional to beat Geale.

Geale also has mandatory defences looming against Australian Sam Soliman for the IBF title and Golovkin for his WBA crown.

Shaw said he was trying to come up with a big fight for three-division world champion Vic Darchinyan, another Australian boxer he represents.

Darchinyan revived his stalling career by winning the NABF super bantamweight title last month.

Shaw was looking at rematches with Jorge Arce, Nonito Donaire and Abner Mares, with Darchinyan having beaten Arce and lost to the other two.

He said he would love to have Geale and Darchinyan appear on the same card in Australia, but neither man would fight again before the new year.

In other news, IBO super featherweight world champion Will Tomlinson will make his second defence on November 21 against Panama's Irving Berry on the undercard of the Danny Green-Shane Cameron fight.

Former two-time WBO interim lightweight champion Michael Katsidis has moved back to Australia and is being trained on the Gold Coast by former national lightweight champion Danny McGrail.
