A reward of $250,000 is on offer to anyone with information which leads to a conviction over a murder in Broome 7 years ago.
The state government today announced it would raise the reward, in an effort to find fresh leads into the death of Josh Warneke in 2010.
"Hopefully this will mean the $250,000 reward will mean perhaps someone new will come forward with some fresh information," said Police Minister Michelle Roberts.
The previous reward was $100,000, but it went unclaimed.
A fresh investigation was launched in April when an innocent aboriginal man hailing from a remote community had his manslaughter conviction overturned.
Now detectives are back in Broome, where they've set up a mobile police outpost urging the public to come forward with information.
Mr Warneke was bashed as he walked home from a night out.
His body was found on the side of Old Broome Road on February 26, 2010.
