However, organisers says the entertainment for the Muster has diversified since last year.

"The Muster is an opportunity for everybody to be a part of an event that truly demonstrates the spirit of Australia, through the participants, the local and national musicians, and the unique atmosphere," Muster coordinator Brian Sansom said.

"The artist line-up for the event has been specifically tailored to appeal to a wide demographic and create a diversified festival that caters to various music styles".

The entertainment programme already includes some incredible talent, such as Pete Murray, Kasey Chambers, Steve Forde, Jimmy Barnes, McClymonts, Adam Brand, and Tripod.

"We are hoping that this year's participants will find the 2008 Muster to be the most enjoyable one, our aim has been to appeal to a wide variety of ages and musical tastes," Muster chairman Andrew Brook said.

"Our focus also remains on upcoming Australian talent and the support offered to rural Australia through our annual Rural Aid Appeal, run at the Muster."
