Towers - who served six and a half years in prison due to his involvement in a kidnap, but has now reformed - was set to box on Hatton Promotions' first card in the Asia-Pacific region against good friend Browne.
Browne’s manager Matt Clark told the Aus-Boxing website that they are looking for a replacement.
Towers, who is undefeated in 14 fights, recently sparred with Wladimir Klitschko.
