The only mosque in Geelong, a city 75 kilometers south of Melbourne was destroyed in a suspicious fire early Wednesday.
Security forces said that the fire was reported at 2.15 AM local time after a nearby dweller heard a loud noise.
According to the Guardian, Greek Orthodox church in East Melbourne, the oldest in Australia, was damaged in a similar suspicious fire two weeks ago.
There have also been four church fires in the Geelong area in the past six months, the paper reported.
Officials from the city also said they did not know if the fires were connected.
The mosque, on Bostock Avenue, is housed in an old bluestone church, but has operated as a mosque for 23 years.
