Gunnedah and District Historical Society's Marie Hobson said the museum had become a "destination", buoyed by its inclusion in the Australian Silo Art Trail. Already, a post about the murals in the Facebook group has been shared almost 7000 times and attracted more than 500 comments.

"We had the highest number of visitors through the door ever when the museum was open between 10am-2pm on Saturday," Mrs Hobson said.

"We've had cars with caravans pulling up to come and see it, and people on their way to Western Australia and South Australia [because] they heard about it on the Silo Art Trail.

"It's really been an incredible experience to see how much tourism it's attracting already."

Perched on Anzac Hill, the museum is an old water reservoir and was a blank canvas for the creativity of award-winning artist Jenny McCracken.

Funded by the Drought Communities Program, the murals depict 'Huey' helicopters and a group of soldiers on the southern side, and on the northern side, soldiers gazing on the Long Tan Cross complete with a painstakingly detailed plaque. The murals were launched on Anzac Day.

There are also treasures to behold inside the museum, which houses five levels of some 17,000 items of memorabilia, artefacts and archives. These historical gems are preserved by the historical society whose vision it was to honour Vietnam veterans through the murals.

"The advantage we've got is people come to see the silo art but we have a museum inside," Mrs Hobson said.

"It's going to make such a difference to our attendance coming in the museum because people will come in to see the display inside."

The museum is open on Saturdays from 10am-2pm and Monday morning while the society members are working.
