Australia's IBF featherweight world champion Billy Dib has signed up solely with Floyd Mayweather, the man regarded as the planet's best-pound-for-pound fighter and who is poised to visit Australia to promote his new charge.

Back in July, Dib signed up with TMT Promotions headed by rap star 50 Cent and Mayweather.

Recent reports of a strained relationship between the rapper and Mayweather have suggested their partnership is over and that 50 Cent may instead link with Filipino boxing superstar Manny Pacquiao.

Dib and his brother and manager Emaid focused on the boxing side of the business rather than the rumours, but confirmed the move to Mayweather Promotions.

"He (Mayweather) was in partnership with 50 Cent but they've decided not to go ahead with that company and Floyd is going to do his own thing," Billy Dib told AAP on Friday.

"This (contract with Mayweather) is a three to four year deal and as I told Floyd this morning I'm in this for the long haul.

"I'm being tutored and mentored by the best in the business.

"One of the things we discussed on the phone is he'd like to probably come out and do some media things with me here, create some more awareness."

Dib is looking to make a voluntary defence overseas before the year is out.

Provided he is successful he will then make a mandatory defence next year against the winner of next month's IBF title eliminator between Cuba's Luis Franco and Argentina's Mauricio Munoz.

Beyond that, Dib said he would look to unify the division or move up to super featherweight.

Emaid Dib described the transfer from TMT to Mayweather Promotions as seamless.

"There's no issues at all, 50 Cent's lawyer has been speaking to our lawyer Adam Houda, he's been dealing with the paperwork," Emaid Dib said.

"Floyd has been communicating with Billy and I on a regular basis and everything that Floyd said has happened and it's been very straightforward and very easy.

"I see a lot of benefits in this move for us, particularly the people that Floyd is working with.

"You've got influential people like Al Haymon and Leonard Ellerbe.

"I think it's going to work really well."
