GREATER Western Sydney has been left fuming at the prospect of having to play finals at the SCG beyond 2018 due to Spotless Stadium's limited capacity.



The AFL has suggested the Giants may be able to play a final against a lower-drawing club at Spotless Stadium later this season, although should Leon Cameron's team play against the Swans or a marquee Melbourne opponent, the SCG and ANZ Stadium will be considered.



Giants CEO Dave Matthews said it was completely unfair if the Giants were unable to play their finals at their home base in western Sydney.



"I'd rather play a home final at Alice Springs than the SCG," Matthews told News Corp.



"I don't think you can call a team Greater Western Sydney and then play home finals in eastern Sydney."



The Giants are also supporting moves to boost Spotless Stadium's capacity from 25,000 to 30,000 (a possible $20 million stadium upgrade).



The AFL scheduled last year's Western Bulldogs-Adelaide elimination final at the MCG, rather than at the Bulldogs' home ground of Etihad Stadium.



But Matthews said a whole lot of organisation needed to go into the decision about whether Spotless Stadium provides an adequate venue for finals.



"A home final should be a home final especially when you’re talking about Sydney," Matthews said.



"When you talk about Etihad (Stadium) and the MCG they’re about three kilometres apart. We've got hundreds of members in Blacktown and to get from there to the city in terms of petrol, tolls and parking it probably costs $70. You can't be classifying it as a home final if you're not catering for your fans."
