The Warlu: Artists of Yuendumu Exhibition has opened at the Dubbo Charles Sturt University campus.
The exhibition comes from the Yuendumu Art Centre, which is about 170 kilometres north-west of Alice Springs. It features 33 artworks.
Curator Lewis Burns said the exhibition was important because it brought Indigenous art from other tribal areas to Dubbo.
"It's important for us to learn the different tribal areas so we're not painting out of country. As Aboriginal artists we've got to learn the styles of our Aboriginal areas," Mr Burns said.
"If you want to teach people about art you have to teach people about the diversity of art from different tribal areas. Australia is like a mini Europe when you're talking about tribal nations."

There used to be 900 Aboriginal countries across Australia, Mr Burns said.
"The more you know about different cultures, dialects, languages, stories, styles - in dance as well as art - the better you understand the people you share a land with," he said.

One of the main differences between the art in Northern Territory and in Dubbo was the dots.
"The dots in central desert art represent sand, they represent particles in the ground, and then the changing colours in those chunks of dots puts together a map. It might not be to scale, but certainly landmarks are in there to tell you where something starts and finishes," Mr Burns said.
"Here, we use dots to represent life, activity or movement. Our dots are used in the specific area of a painting to represent the life force of an animal or person, or activity in the river. Around the outside of a footprint they represent the life force of the thing that left that footprint."
Around the world the Aboriginal dots were instantly recognisable, said Mr Burns, but most people didn't realise the differences in the representation.
The exhibition will be open until May 4.
Jack Randell said CSU was a community art space. There was a call out for exhibition proposals and would be a calendar of work to be shown throughout the years, he said.
