South-west Sydney is set to emerge as a candidate for A-League expansion and the home of Australian football's national teams with plans for a boutique football stadium to be unveiled this week.

The draft annual budget for Fairfield City Council will be unveiled at chambers on Thursday evening and among the top items is funding for a stadium that could prove a game changer for football in Sydney.

Fairfield Showgrounds is set to undergo the first stage of developments to include a football-specific boutique stadium with $8.5 million already pledged from the council for its upgrades. The funding pledged towards renovations could soar close to $20 million if the council is successful in its request for state government co-funding.

It's a far cry from the $1.6 billion renovations for Parramatta, ANZ and Allianz Stadiums, but the proposed funding for the new sporting complex in Sydney's south-west could include a stadium with an initial capacity of about 10,000, a second synthetic football field adjacent to the stadium that will be the foundations of a regional "centre of excellence" for junior development.
