The artwork is the background of a painting by NSW Indigenous artist Henry Crase.

It depicts the journey of Jason Trent McColl, an Aboriginal cadet at St George Bank.

"It's a symbol for Indigenous people that it doesn't matter what you do or where you're from you can always have a journey," Mr McColl said.

"The bank has been on the journey with me; now people can always see that the bank has supported me.

"What you can dream you can achieve."

Mr Crase explained the artwork to the Daily Liberal.

The big and small circles represent the deep and shallow water and the white circle surrounding shows the waves washing up to the shore.

Australia is depicted in the middle of the artwork and believed by Indigenous people to be Mother Earth.

Tracks from Sydney to Tennant Creek are in the map of Australia,with the black dots representing footprints between the locations.

The artwork also features a kangaroo, boomerang and male and female members of a tribe.

Mr McColl originally asked Mr Crase, a friend of his, to paint his journey, much like his ancestors did in his homeland.

Mr Crase said he was delighted to be approached by Mr McColl and was shocked when he was told his painting would be the design base of an ATM decoration.

"I'm highly honoured to do it because Jason is a friend of mine and this is his personal journey," he said.

"I can't believe it [is on an ATM] I said to Jason when he told me 'you're joking, I would grab you and kiss you and do back flips if I could'.

"It's something I didn't even imagine would happen."

Mr Crase's painting was donated to St George Bank and is displayed at the company's headquarters in Sydney.

Mr McColl is studying a Bachelor of Business and Commerce at the University of Newcastle.

Career Trackers initiated his cadetship with St George Bank.

Career Trackers is a non-profit organisation that creates internship opportunities for talented Indigenous university students.

It is hoped Career Trackers interns will complete a multi-year internship in the private sector and become full-time employees.

St George Bank regional executive Dan Pobje said he thinks the design is a great NAIDOC Week initiative and is certainly visually pleasing.

"NAIDOC week is big in Dubbo and this is a way to represented Indigenous people within St George's, as they're an important part of the community," he said.

"It's a shame we're going to pull it down after NAIDOC week.

"It's a bit different and has a good message."
