WA Police have confirmed they were called to a home on Constance Street around 1:25pm on Saturday after reports a man had been shot. They have not said anyone has been taken into custody in relation to the incident.

A neighbour, who gave her name as Dee, told reporters, "I was indoors, watching the cricket and I heard this almighty bang. I opened my door and realised people were down my neighbour's driveway."

She said she went straight over and saw an injured man fall off a fence into the driveway and a woman told her to "go away".

Dee said she told the woman, "I beg your pardon?" and asked the woman if she'd rung an ambulance.

She said another woman was trying to help the man breathe before an ambulance arrived and took him to hospital.

Dee said she heard a loud bang before going outside to see an injured man fall from a fence on to her neighbour's driveway. ( ABC News: Evan Morgan Grahame )
