Artists from more than 30 remote desert communities will be represented in Alice Springs for Desert Mob, Central Australia's largest Aboriginal art festival.

The annual event, which is celebrating its 25-year anniversary, bills itself as a snapshot of what is happening in the many remote arts centres in Central Australia, and includes an arts symposium, exhibition and marketplace.

"It's a special year for us celebrating 25 years, the longevity of this event which still remains one of the key events on the national Indigenous art calendar," Desart chief executive Phillip Watkins said.

"With us at Desert Mob, it is something that does not happen anywhere else in Australia.

"It's got a special Central Australian desert energy."

He said women's choirs and dancers will mark the anniversary, which also includes a photography prize.

The arts exhibition at Araluen arts Centre opened last night, the symposium will be held today and the marketplace will commence on Saturday.
