Asutralia has gone back to hopefully 3 teams in the 2014 ACL: Two direct entries to the Group Stage : Western Sydney Wanderers and Central Coast Mariners One into the qualifying playoffs : Melbourne Victory It is unclear whether losers in the playoffs get a berth in the far lesser competition of the 2014 AFC Cup (it has been the case in prior years, but The-AFC keeps tinkering with the format); or whether a team such as MV would even want to be in that competition if it doesn't make the ACL http://www.the-afc.com/en/about-afc/afc-committees/1127-executive-committee/27301-afc-exco-slots-261113.html
I think you mean Central Coast, not Brisbane.... And the rumours are that Australia (also CHN, THA, UZB, QAT, UAE) wont get drop down AFC Cup spots.
