Let the Mariners beat the Roar over two legs first before we know if this issue is an issue or not.
The finals series are not part of the A-League competition as such and are owned by the FFA.
They will choose the ground that will maximise the revenue and the viewing potential.
I believe that Allianz stadium is less than an hour away from most Central Coast supporters, which is what most people in big cities have to do to get to the city centre anyway.
Allianz Stadium will only be a home advantage for Sudney FC if they ever get there, it certainly won't give Brisbane any advantage.
