Victoria Police confirmed emergency services were called to a fire at an "unoccupied house under construction" in Torquay at about 1.50am on Friday.

"Crews quickly brought the blaze under control and only the front entrance and porch were damaged," a Victoria Police statement said.

"Police are yet to make any arrests and the investigation is ongoing."

Vlastuin - who is playing in Saturday night's AFL grand final at the Gabba - and his partner own the property.

The Tigers confirmed they were aware of the incident.

"The club is aware of a suspicious fire which occurred early Friday morning at a Torquay property owned by Richmond player, Nick Vlastuin and his partner," Richmond said in a statement.

"The property suffered minor fire damage to the front entrance, and there were no occupants in the home at the time.

"As Victoria Police are investigating the matter, the club will make no further comment."

Vlastuin can win his third AFL premiership in four seasons when the Tigers play Geelong on Saturday night.
