"The season is too short," Ferguson said, as the A-League runners-up finalised preparations for their pre-season camp in South Africa.
"To make the competition fair we need to all play each other four times, two at home and two away. That would add to the current format and balance out the long-haul games.
"Last season we had to travel to Wellington twice, but they came here only once. To me that's not really fair."
Current financial restraints on the league will probably not enable that to happen soon, but Ferguson knows the competition has to expand at some time.
"A six-month lay-off for the players is not good. It's not good for any professional athlete, so we have to look at growing our season," Ferguson said.
"The addition of an FFA Cup I believe will add to the excitement, but we need to play more games.
"Last year our off-season was 22 weeks. This year it's only 16, so we're slowly getting there."
