Football Federation Australia chairman Frank Lowy says it's only a matter of time until the A-League expands to a 12-team competition and adopts a system of promotion and relegation.
In particular, he said the introduction of a multi-tier model was all but inevitable.
"I think we should take that into consideration because eventually we will have to have promotion and relegation," Lowy told Fox Sports.
"In my estimation, we will be made to do that."
Lowy said the FFA was being encouraged by the sport's governing bodies to expand the competition.
But the shopping centre mogul said they understood the process would take time and weren't pressing too hard.
Two more teams should also be introduced by the time the current broadcast deal is replaced following the 2016/17 season, Lowy said.
From there he said a 14-team competition could also be on the cards.
Wollongong, Canberra, Cairns and south-west Brisbane have all been touted as potential homelands for new A-League clubs.
