Jackie O, Timomatic, Sarah Murdoch, Guy Sebastian, Melanie Brown & More At 2012 Australian Commercial Radio Awards

It was a veritable who's who of the country's hottest radio personalities last night, when they hit the red carpet for the 2012 Australian Commercial Radio Radio Awards (ACRA). The event, which was hosted by international reality TV personality Sharon Osbourne and Merrick Watts, saw celebs like Melanie Brown and her husband Stephen Belafonte, Jackie O, Guy Sebastian, The Veronicas and Sarah Murdoch hit the red carpet on a chilly Sydney evening. WSFM's breakfast show announcers Amanda Keller and Brendan "Jonesy" Jones won the most coveted award of the night — best on-air team &mdash, while The Kyle & Jackie O Show won best networked program.
