For the sake of fairness, Sydney CEO Andrew Ireland believes any all-Sydney final hosted by Greater Western Sydney this year should be held at ANZ Stadium.

The Swans' stunning turnaround has suddenly made a second consecutive all-Sydney final a genuine prospect come September.

Unlike last season's historic knockout clash when the Swans finished ahead of the Giants on the ladder, any rematch would more likely be hosted by the Giants, which sit two matches ahead of their rivals.

In last season's historic Sydney derby qualifying final, the Swans were forced to cede their home-ground advantage at the SCG in favour of the larger Olympic Park venue.

"It's a fair way off yet, the only thing I'd say is that last year we were the higher-ranked team and the AFL made a decision it should be played at ANZ and not at the SCG," Ireland said on Tuesday.  

"The view was it was going to be a very big crowd.

"If you talk about consistency then I would have thought there's got to be some consideration about the 40,000 people who might get locked out if it's played at Spotless."

Last year the Swans ended their ANZ Stadium deal one year early, allowing the club to play all its home matches at the SCG.

An agreement announced in August between the AFL and ANZ Stadium authorities said the two parties had agreed it was in the best interests of the Swans’ supporter base that the club played its finals at the SCG, unless the club met its cross-town rival, where the greater capacity of the ANZ Stadium would serve football extremely well.

At the time, AFL CEO Gillon McLachlan said, "If the finals fixture produces a head-to-head match between the Swans and the Giants, this would possibly be the biggest game in NSW in the history of our sport and we would play that game at ANZ Stadium," he said.

The qualifying final in 2016 attracted a crowd of 60,222, while the capacity of Spotless Stadium is 24,000.

ANZ Stadium ground management confirmed there had been no talks with the league about this year's finals.

But McLachlan suggested in February a return to the 83,500-capacity stadium may yet be possible.

Ireland also threw up the controversial option of the SCG, which can hold 46,000, something Swans chairman Andrew Pridham agreed with.

"The SCG would be my pick – I'm being serious," Pridham said.

Should the Giants host an interstate side in the finals, Ireland stressed they should be allowed to remain at Spotless, especially given last year's preliminary-final loss to the Western Bulldogs did not sell out.

"Hopefully the teams can play at home if they've earned that right," Ireland said.

"But as in Melbourne, Geelong hosts some teams at Geelong but if it's a big game it goes to the MCG."
