Sydney and Brisbane, the heartland of Australian rugby, will vie to host more Tests due to declining crowd numbers elsewhere in the country.
A concerning drop in attendances and the fickle Gold Coast market has put the spotlight on Wallabies crowds ahead of the Rugby Championship Test against Argentina at Cbus Super Stadium this weekend, when the tourist strip may be hosting its last Rugby Championship match if ticket sales don't improve before kick-off on Saturday.
Fewer than 15,000 spectators are forecast at the Test, only the second to be played on the Gold Coast. The first, also against the Pumas in September in 2012, attracted a far better attendance of 22,278.
Slow ticket sales prompted Ewen McKenzie to warn locals the city would lose hosting rights if they did not go closer to selling out the 27,000-seat venue, the Wallabies coach saying: "You've only got seven domestic Test matches to make all your money in any given year, so the goal is obviously to fill stadiums."
The Coast has traditionally had problems drawing crowds to all football codes, highlighted by NRL club Gold Coast Titans posting a record low average of 13,194 this season, but the Australian Rugby Union's concerns also spread west and south.
The Springboks Test at Paterson Stadium in Perth drew only 25,718 spectators last weekend - significantly fewer than for the fixture in 2012 (34,377) - while Melbourne's Etihad Stadium also was only half full when 27,189 fans turned out to watch Australia play France in June.
Sydney, meanwhile, has struggled to pack out the 83,000-capacity ANZ Stadium of late while Brisbane's Suncorp Stadium was only two-thirds full for the Test against France, but both regularly ensure good gate receipts. New South Wales Waratahs and Queensland Reds also enjoy healthy crowd support in Super Rugby, giving rugby's main centres - who both generally host two Tests each year - a better case.
Next year will create bigger challenges for the cash-strapped Australian Rugby Union, with the Rugby World Cup, to be held in England in September-October, reducing the number of domestic Tests and expected revenue.
