Through his company MGM, Mr Mundine and his business partner Gosh Daher have designed the first Indigenous roadside barriers.

The barriers will be on display on the Victoria Street roundabout.

Mr Daher said it was a year in the making to get the barriers onto the streets of "beautiful Dubbo".

He wanted it to be an uplifting project for Indigenous kids. There were 22 young people involved in the project who were able to learn new skills throughout the conception and creation of the barriers.

Mr Daher said they were mentoring and educating them, while always making sure their mental health was okay.

"We're just very proud and enjoying this moment," Mr Mundine said.

"We employ a lot of Indigenous brothers and sisters. We want to give as many employment opportunities as we can and show if you put your mind to it, anything is possible."

The barriers are painted with a large snake. It's done in the colours of the Aboriginal flag with the black representing people, red for the blood, orange for the earth and yellow for the sun.

Mr Mundine said he hoped the company would continue to grow with more decorated barriers installed across the state.
