Broc Parkes will join Michael Laverty in the PBM MotoGP team for the 2014 season.
Parkes, 31, is a double title runner-up in World Supersport and has also spent several seasons in WSBK, including one year (2009) with the then PBM Kawasaki team.
Set to be the only Australian on the 2014 MotoGP grid, Parkes has made one previous GP appearance - as a 125cc wild-card in 1999 - before starting his world championship career in 2001.
"Firstly, I'd like to say a massive thanks to Paul Bird for the opportunity to work with his team once again; I'm really looking forward to it," said Parkes.
"This is the premier class and it's every rider's dream to race in MotoGP. I know this is going to be a tough season but I'm certainly up for the challenge, I can't wait to get started."
The team state that Laverty, 32, and Parkes will race "PBM Aprilias", suggesting PBM's own chassis with the Aprilia ART engine rather than the full ART package.
"We learned so much in year one that I'm delighted Paul has continued his involvement with MotoGP and that he's given me the opportunity to continue with the project," commented Laverty, who raced the new PBM-Aprilia for much of this year.
"Everyone has told me that year two is much easier so the aim is to put into place what we have learned and to raise our game accordingly. The class is going to be a lot tougher with the new production bikes but our aim is to consistently score points."
PBM are expected to continue in British Racing Green livery, with the team to be officially unveiled at the London Motorcycle Show from February 14-16.
Team owner Paul Bird stated: "We've done a lot of spade work in MotoGP over the past two seasons so the plan is to build on that and work with our partners and Michael and Broc are very capable of delivering."
Last month's provisional MotoGP entry list had named Laverty on a 'PBM/ART' with his team-mate 'To Be Confirmed'.
