Sydney could become the permanent home of the A-League grand final as part of a NSW government plan to bid for the hosting rights for the competition's decider, regardless of the teams competing.

Fairfax Media understands discussions have taken place within the state government to table a bid to Football Federation Australia to secure the long-term hosting rights for the event, commencing as early as 2019. While still in an early stage, the proposal includes ANZ Stadium, Allianz Stadium and a newly renovated 30,000-seat Parramatta Stadium as candidates to stage the annual decider, operating on a sliding scale pending the stature of the teams competing.

The initial proposal in discussion is in response to the $1billion investment in stadia from the NSW government, which is eager to consolidate a series of major events to ensure traffic, tenancy and an influx of tourism with the new venues.

It is understood the NSW government was impressed by this year's grand final between Sydney FC and Melbourne Victory, which attracted approximately 10,000 interstate attendees. That prompted talks about whether Sydney could become the home of the decider, as it is for the NRL final, and as Melbourne is for the AFL grand final.
