Police claim the man left the house before the officers arrived but while they conducted inquires at the address the man returned and attacked the senior constable with a Samurai sword.

The officer was struck to the head and sustained a large gash and a fractured skull. He also required 25 stitches to fix the wound and remains in a stable condition at Royal Perth Hospital.

Mr Tilbury said it was merely the latest example of the danger faced by officers but said he didn't want to use the case to try and force the WA government to reconsider its stance on the police's pay model.

"These are horrendous injuries and highlight the dangers and difficulties police officers face on a daily basis when they put their lives on the line," he said.

"I don't want to highlight this and make it political and relate it to our pay plan at all, but what this is is another incident where one of our members has been attacked, and they are attacked on a daily basis.
