A redress scheme for medically retired police officers in Western Australia could be paid for with a small, one-off emergency services levy increase, it has been suggested.
Medically Retired Western Australian Police Officers Association president Dave Bentley says officers who are not physically or psychologically fit to continue have so far been cast on the scrap heap.
The same section of the Police Act that is used to retire corrupt and criminal officers is also used for those deemed medically unfit, and both get one month's pay.
Police Minister Michelle Roberts has promised to end that indignity through a legislative amendment, which she plans to put before parliament early next year.
She has also pledged to make an announcement about a redress scheme before the end of this year.
Mr Bentley said successive governments had failed to fix the injustice but he believed Ms Roberts was "fully committed".
"I'm quietly confident they're going to deliver," he told AAP on Thursday.
Mr Bentley suggested the cash-strapped state government could pay for the redress scheme with a one-off hike to the emergency services levy.
The public were happy to pay higher compulsory third-party premiums in 2016-17 so those catastrophically injured in car crashes were compensated regardless of fault, and may feel the same way about helping police officers, he said.
"I will really be glad when this is resolved because we'll have our dignity and put the politicking behind us," Mr Bentley said.
"I don't want this to slip down the list. I know they want to deliver it."
He estimated about 420 officers had retired for medical reasons.
Ms Roberts also committed to bringing in a workers compensation scheme for police during the McGowan government's current term.
WA is the only state in Australia that does not have such a scheme.
Ms Roberts agreed a scheme should have been introduced years ago but said it was a complex matter.
