Police are investigating after a suspicious blaze destroyed a struggling footy club’s premises last night.

At about 11.30pm, police and fire crews were called to the Nangwarry Saints sporting club on Bednall Drive after neighbours reported seeing flames.

When emergency services arrived, the club was fully engulfed in flames, although they were quickly able to control the blaze.

"After a devastating night/morning, nothing will keep us down. Come along and help us more now than ever, pop down to training," the club's official Facebook page posted this afternoon.

There were no reported injuries and investigators are making further enquiries.

The blaze comes as the latest blow for the Nangwarry Saints whose A grade side have failed to win a single game since July 2014.

Up until the mid-2000s, the club was strong with the majority of its players also employed at the local timber mill.

But a spate of job cuts at the mill saw employment drop from hundreds in 2000, to just a couple of dozen last year.
