The band, whose members met during their studies at religious college Hillsong, play outside Villawood Detention Centre every Sunday morning.

Their electro pop beats proved popular at the Clash final, held at Ingleburn RSL, but keyboard player and singer Stu Hawkins said the win was unexpected.

``It took us completely by surprise,'' he said.

Hawk ins, like two others from 11:59, is from Britain and has lived in Australia for the past three years. One band member also moved here from Canada.

``We like to think we're a Brit pop band that lives in Australia,'' he said. ``We seem a little different certainly to the bands we see in pubs.''

But 11:59 are no stranger to the Sydney pub circuit. They have played around Manly and at the Annandale Hotel.

The prize included having their songs recorded, a filmed music video clip and marketing and promotional material.

11:59 will release some Christmas songs on their Myspace page next month.

Macarthur Clash runners-up were bands Burn the Dire Moments and Dynamic State.
