Three separate suspicious fires lit across Adelaide overnight, including one destroying southern suburbs netball club

Firebugs across Adelaide caused a ruckus last night as three separate suspicious fires, involving two cars and a southern suburbs netball club, were lit.

In Ottoway, a V-Commodore was discovered ablaze in the front yard of a Larsen Ct address at about 1:30am.

Two MFS appliances with breathing equipment managed to contain the fire to the vehicle. There were concerns the fire would spread to a nearby house due to its proximity to the car.

Meanwhile, in Banksia Park, a Holden ute was discovered engulfed in flames along Marsha Drv at about 1:50am this morning.

Two MFS appliances extinguished the blaze.

Police say the estimated cost of damages for each car would be the vehicle's total cost of value.

Meanwhile, the clubrooms of the Aldinga Netball Club have been completely destroyed by fire.

The complex, which included a canteen, offices and a store room, has been completely destroyed and about $50,000 worth of damages were caused.

Twenty-two firefighters from four appliances and a bulk water were called in just after 2:30am to discover the sports club was fully alight.

The fire was contained in 20 minutes.

The cause has not yet been determined.

Club President Samara Bryant described the incident as "heartbreaking".

"We've lost trophies. We're lost history," she told The Advertiser.

"All our equipment, our uniforms, all our balls (are destroyed)."

The club — which is hosting a semi-final tomorrow — also lost food and cooking equipment which was stored in the clubrooms for the event.

Anyone with information has been asked to contact Crime Stoppers on 1800 333 000.
