Ulsterman Damaen Kelly will face IBF world flyweight champion Vic Darchinyan in Sydney on November 25.
Armenian-born Darchinyan is a rising star in Australia having won all 24 of his contests, 19 via knockout, and will be making the third defence of his title.
It will be Kelly's second attempt at winning the IBF belt. Two years ago he lost to Colombian Irene Pacheco, who subsequently lost to Darchinyan.
Kelly's manager Tommy Gilmour said: "This is a huge opportunity for Damaen. It has taken a long time to get the deal sorted out but now it's done and I believe Damaen can go and get the title.
"We tried to get the fight for Belfast but the Australian camp seemed determined to stay in Sydney, but fighting away from home won't worry Kelly.
"He's a very experienced fighter now. A win would take his career to a level he has not been at before."
