The Temper Trap, Empire Of The Sun, Sarah Blasko, Kate Miller-Heidke and Troy Cassar-Daley are in the hunt for the prestigious APRA song of the year honor, which will be announced June 21 during the annual APRA Music Awards in Sydney.

APRA's peer-voted song of the year honor is one of nine categories for which nominations were announced today.

The big contenders include triple-nominated rockers the Living End and R&B singer Jessica Mauboy, while the Temper Trap and Empire of the Sun are among the double-nominated artists. Mauboy is up for breakthrough songwriter, her song "Running Back" is a chance for urban work and her hit "Been Waiting" will vie for the most played Australian work of the year trophy.

Meanwhile, the Living End's "Ring the Alarm" is up for most played Australian work and the song gets a nod in the new APRA category for rock work of the year. The Living End's "White Noise" -- winner of the APRA song of the year award in 2009 -- is also a chance this time for rock work. "White Noise" was eligible again because its release fell within the designated release period, from July 1, 2008 to Dec. 31, 2009.

The gala at Sydney's Convention Centre will cap off the three-day APRA Song Summit. Eight of the 12 awards handed out on the night are based on statistical analysis. The APRA board of writer and publisher directors decide the songwriter of the year award, the breakthrough songwriter honor, and the Ted Albert award for outstanding services to Australian music, which was bestowed last year to Sony Music Australasia chairman/CEO Denis Handlin.
