Julia Gillard announced the election for September 14, going head-to-head with big matches for the AFL, NRL and the Wallabies.
That weekend is semi-finals time in the AFL and qualifying and elimination finals for the NRL - with matches set down for the Saturday.
The AFL said there was a simple solution for footy fans: get up early and vote.
"It will be week two of our finals, but that's no impact for us. Our fans of whoever is playing that day will just need to vote in the morning," said an AFL spokesman.
The NRL is confident punters will be at least as interested in the outcome of the league playoffs as the election result.
"It's not the first time it's happened, and it won't be the last time. But people will still be more than interested in the footy," said the NRL in a statement.
In Perth on that Saturday night, the Wallabies host Argentina in the Rugby Championship.
The ARU doesn't expect their crowd to suffer at all from the election.
"The Wallabies Test against the Pumas will kick-off when polling booths close in Western Australia," an ARU statement said.
"The ARU does not anticipate any impact on attendance for the Wallabies v Pumas Rugby Championship Test that evening."
