Victoria's grand final public holiday will almost certainly be dumped if the Coalition wins the 2018 state election.

Opposition Leader Matthew Guy has warned Victorians are getting too many days off, arguing the increased leisure quota will hurt the state's ability to compete and create jobs.

"I think it is pretty clear that a Coalition government would find it very difficult to keep it," Mr Guy said. "Shadow cabinet talked about it this morning, the party room will discuss it again tomorrow, we'll make some more comments in that space in the near future."

The grand final public holiday means Victoria has 13 public holidays a year, the equal highest number of public holidays in the nation along with South Australia and the ACT. There are 12 days off a year in NSW, 11 in the Northern Territory, 11 in Queensland, 11 in Tasmania and 12 in Western Australia.
