The Southern Hemisphere's biggest country and roots music festival will rock and country the Willowbank Raceway site on March 13 -15  with multi-platinum selling artist Lady Antebellum headlining.

"With what is basically a metro site located off the Cunningham Highway just one hour from both Brisbane and Gold Coast airports and accessible by road, train and shuttle bus options, travel to and from the event will be much quicker and easier," Rob Potts Entertainment Edge CEO Rob Potts said.

"There is also an unlimited supply of accommodation within an hour radius of the site - including Brisbane, the Gold Coast and Ipswich, along with a much-expanded camping area and new glamping options. Now in its 8th year, CMC Rocks has become a huge fan favourite festival, with country fans flocking to the event from all over Australia and internationally. The new larger site at Willowbank Raceway, South West of Brisbane, opens up exciting options for us in the way we stage the event, along with greater catering and entertainment options, enhancing the festival experience for everyone."

The festival was first held in Thredbo's Snowy Mountains in 2008 and moved to NSW's Hunter Valley in 2011. 

ARIA-winning and multi-Golden Guitar winner Troy Cassar-Daley is the other performer announced for CMC Rocks QLD 2015, with more artists and the ticket information announced in coming weeks.
