Four boats have been destroyed in a fire at Hillarys Boat Harbour in Perth's northern suburbs, the second time a blaze has struck the marina in just over four months.
Firefighters were called to the harbour at 10:35pm after reports a boat was ablaze.
The fire began on a single boat before spreading to nearby vessels, and large smoke plumes caused a HAZMAT warning to be put in place for the area.
It took the Department of Fire and Emergency Services until about 2am to extinguish the blaze.

Four vessels were completely destroyed by the flames and subsequently sank.
Scott Bulloch, the station officer at Duncraig Fire Station, said the cause of the fire could not yet be determined.
"By the time fire investigation arrived, all four boats were underwater," Mr Bulloch said.
"Once we receive more information, video footage, things like that, they can look at it further and we can come up with a conclusion from there."

Mr Bulloch said he had spoken to the Department of Transport and they would "look at getting a contractor in place to ... refloat the boats".
"There's quite a bit of fuel that was on those boats so we've been working with the Department of Transport, pollution response, in containing that fuel to the area where the boats were," he said.
Fire 'raging'
Andrew Beale, who was staying on a boat at Hillarys for his work in vessel maintenance, said he heard an alarm and did his best to stop the blaze.
"[We] pulled the fire reels and just started to douse [the fuel sources]," he said.
"We just kept water on the petrols as best we could until fire and rescue came and the police came.
"By that time, one was completely gone, and next minute, three, four, all the other boats were caught on fire and burning as well.

"It was amazing how quick it happened.
"Fortunately for everyone, there was no one on board."
Mr Beale said after 10 minutes the fire was "raging".
"A lot of toxic smoke, a lot of plumes," he said.
It was the second boat fire at Hillarys in four months, after a luxury 50-foot vessel was gutted by flames last September.
Crews were called to the marina just before 11am on Saturday September 27, and had to contend with thick smoke as they battled the blaze.
Thirty firefighters attended, and fought challenging conditions in their efforts to stop the fire spreading to neighbouring vessels.
