Gunnedah's Vietnam War murals have been shortlisted for the 2019 Australian Street Art Awards.
The town's new attraction on the water tower museum has already drawn visitors from around Australia since the official opening on Anzac Day.
Society president Bon Leister said he was "quite thrilled" when he found out the murals were among finalists in the best monument or memorial category last week.
Street art judges said the early completion of the mural delivered "an immediate community benefit" and meant Gunnedah was included in "many grey nomads' travel plans over the winter months, resulting in additional economic benefits for the town".
"The project is contributing significantly to making Australia a more vibrant, creative and interesting country - somewhere that international visitors, as well as domestic travellers, will want to explore," they said.
"One of our members did an attendance graph going back about four or five months and since the murals have been on the wall ... the graph lines went vertical," he said.
The murals are now included in the Australian Silo Art Trail and "people from all over Australia are coming in".
The mural on the southern side of iconic "Huey" helicopters and a group of soldiers was inspired by an image from the war etched in granite on the Vietnam War Memorial in Canberra.
The second mural facing north depicts soldiers standing at attention beside the Long Tan Cross.
The society is now working behind-the-scenes with Ms McCracken to prepare a design concept for a new mural on the western side to drive grant applications.
If the society is successful in attracting funding, Mr Leister said they would like to recognise the vital role nurses played in war.
