WA could soon have a new derby in town with a Fremantle-based consortium making a bold push for a port city team to be part of the lucrative and highly successful Big Bash League.

Fremantle Breeze would be based at Fremantle Oval, which is about to undergo a $20 million revamp to turn the aging venue into a state-of-the-art stadium, if it were to get a shot at the Twenty20 competition.

And, with the Dockers moving their training headquarters from Fremantle Oval, to a swanky new $109 million facility in Cockburn Central next year, the ground will be all but empty during the summer months.

With a capacity of more than 20,000 people, Fremantle Oval would be the ideal venue for Twenty20 cricket with Perth Scorchers games at the WACA regularly selling out.
