Victoria Police employees have been voting on a five per cent annual raise over four years for frontline officers and a 4.5 per cent a year wage rise for other officers.
Voting opened on Monday and will close on Friday afternoon.
The Police Association and Victoria Police struck an in-principle deal in May on a nine-day fortnight and 16 per cent pay rise across four years.
But it was knocked back by staff in July, leading hundreds of police to walk off the job for the first time in 25 years.
The Fair Work Commission was asked to intervene but declined, sending the force and union back to the negotiating table.
A tentative deal was reached in late January but had to be put to a staff vote for final approval.
It comes after Shane Patton was pushed out as chief commissioner on February 16 following a union-led vote of no confidence by rank-and-file officers.
More than 12,600 of the 14,571 union members who voted - or 87 per cent - did not feel Mr Patton could lead or manage the force into the future.
Mr Patton initially flagged his intention to remain but resigned two days later after the state government decided his position was untenable and appointed Rick Nugent as acting chief commissioner.
Deputy commissioner Neil Paterson followed him out the door after being told his contract would not be renewed.
In November, Mr Paterson was referred to the state's anti-corruption commission over an alleged road rage incident outside the city campus of private school Haileybury in July 2024.
