Western United are gearing up to play their final home game of the season against Central Coast Mariners at Geelong's GMHBA Stadium on Sunday - and it could be their last for some time.

Next season's plans for the A-League new-boys are in flux.

Other western suburbs venues closer to Melbourne - including the Whitten Oval and Melbourne Knights Stadium in Sunshine, perhaps even the Melbourne Showgrounds - are being floated as potential venues as the club seeks to strengthen its identity and attract supporters as it awaits construction of its planned stadium in Tarneit.

Western's final two home games this season - against Western Sydney Wanderers at the end of March and Melbourne City over Easter - will be played at Mars Stadium in Ballarat.
