WARRNAMBOOL and District league club presidents are concerned players will jump to other competitions if one league decides to play this year.
WDFNL clubs will vote on June 24 whether they go ahead with season 2020 or not.
The Hampden league is meeting on June 10 to weigh up its state of play.
Player retention, the possibility of no crowds at games and finances are among the key concerns flagged by clubs.
The chances of seasons going ahead hinge on further easing of state government restrictions.
Panmure president Maree Condon said leagues stopping at the same time would stop players switching to other clubs.

She hopes players don't switch if the Hampden league stops and WDFNL continues or vice versa.
"I hope (our players) would stick with us," she said. "Let's face it, only a certain amount of players can fit in one team. It doesn't mean you can fit (players from other leagues) in."
She hoped her club would be loyal to its current players if it came to HFNL players wanting to join the WDFNL.
New Kolora-Noorat president Paul Dunn said if a WDFNL season goes ahead and the HFNL doesn't, the Power would remain loyal to its current players.
"If they want to come and play with us that's fine but we've got to play our own kids first," he said.
"We wouldn't be dropping any of our players that's for sure. It wouldn't matter the calibre of the players."
Dunn said it would be sad if it went the other way and players left because the WDFNL stopped while the HFNL went ahead. But he feels that would be out of the club's hands.
"We'd hope we'd pick them up again the following season," he said.
South Rovers president Dennis Bushell believes recruiting HFNL players could compromise the integrity of the WDFNL.
"In some ways you could almost buy a premiership," he said."We should act as though all leagues are running."
Old Collegians president Jason Moloney and Nirranda counterpart Jake Harkness said the idea of switching was hypothetical at this stage as both leagues weigh up their seasons.
Moloney, who was pleased the league now had a date to decide its next move, hoped both leagues would make the same decision and players would remain loyal to their clubs.
Harkness believes players leaving to play in another league was the the biggest danger of choosing to cancel the season.
"If the Hampden goes ahead and their reserves are short I'm sure there will be District league players playing in their league and that is a danger," he said.
"I believe 99 per cent of players wouldn't but there might be a couple. It is a hypothetical question and it is something we don't know will happen yet.
"I would think clearances would be closed before any competition is started anyway."
