Artist Jara Gillick-Lewis said the organisation aimed to give young artists a platform for their ideas.

"We want to inspire and engage them and hopefully they can take (their skills) further," Ms Gillick-Lewis said.

"There is potentially a chance for them to come back next year and get their own wall or piece.

"We want to see them develop their skills and take them further and further."

Ms Gillick-Lewis said the group also promoted, including female artists.

"We are eroding that boundary that street art is just for males," she said.

"The group also included local community children as well as kids from rural areas.

'It;s very inclusive, brings people in and gives them a space where they are comfortable to express their ideas."

Ms Gillick-Lewis said this year she was inspired by GTM's retro poster artwork.

"I hope it's very retro , stylised and captivating. I am going for a bit of an oasis vibe," she said.

"I am normally an illustrator but I do graffiti as well.

"You can start out illegally but I don't like working and looking over my shoulder.

"So I started by getting access to walls and tapping into festivals. 

"If you want to paint, you find a way but you've got to practise."
