In western Queensland, roughly 90 kilometres west of Windorah, a sacred well was recently filled with 25kg of concrete and other material by an unknown vandal.

It is one of a number of wells in the area with a history dating back up to 5000 years which have been officially recognised as heritage sites.

In the past, the Mithaka people relied on these wells as sources of water during their journeys, taking measures to protect them from animals by using sticks.

Mithaka Aboriginal Corporation have undertaken the removal of approximately 25 kilograms of concrete, stones, and soil from the well.

General manager Josh Gorringe told News.com.au the vandalism was "pretty disgusting."

"There is no easy way to put it, it is a site that has been there for thousands of years. I don't understand why anyone would go and pour concrete," he said.

"If someone graffitied a church everyone would be up in arms," he said.

"For us, it is a history that is definitely under-researched in Australia and a history that should be better taught in Australia than what my people went through back in the past."

The incident is currently under investigation by the Windorah Police and Longreach Criminal Investigation Branch.

Police said the damage appears to have been deliberate, and it is believed to have occurred sometime in September.

"Samples of the material have been taken, the site has been photographed by a forensics officer, the Longreach Criminal Investigation Branch (CIB) have conducted an inquiry with the rangers," Acting Inspector Chris Smith told the ABC.

"To do the work that was done to the well … it's embarrassing for that matter to happen in our area.

"We're seeking any public assistance from anyone travelling on the roads, if they have any dashcam footage or anything like that."

Mithaka Aboriginal Corporation has been contacted for further information.
