A Perth father charged with setting his daughter on fire has faced WA's Supreme Court on Monday.

Edward John Herbert, a tiler known to neighbours as "Eddy", allegedly doused his three-year-old daughter and her two siblings in petrol and set them alight at their home in Holbeck Street, Doubleview, on August 28.

The children's mother ran into the street for help.

Two neighbours came to help, one an off-duty police constable who extinguished the seriously injured three-year-old girl using a blanket.
