Aboriginal Affairs Victoria is investigating an incident which saw a GWMWater contractor run a grader through a known Aboriginal heritage site, disturbing Aboriginal artifacts including quartz tools.

Barengi Gadjin Land Council acting chairperson Suzy Skurrie said she was emotional when visiting the site.

"With all our sites, whether it be our scar trees, our quartz scatters, rock art sites, spiritual places, perhaps even the ones you can't physically see, they all have the same importance," she said.

"When any of our cultural sites are damaged the whole community feels it.

"We're not out to blame anyone. These things do happen and it's very unfortunate."

Ms Skurrie said the site was important because it confirmed her people lived in the area.

"It's a celebration that our people were in the area, that our people occupied the land, it is validation that they were there," she said.

"It connects us to our country and that's still so important to us as Aboriginal people today."

Barengi Gadjin Land Council cultural heritage manager Gail Harradine said it was important the Aboriginal community had the opportunity to visit the site and talk with people involved in the incident.

"It's important to us as traditional owners to be able to tell people lived and worked in the landscape," she said.

"It's a very peaceful spot out there. We all felt very close to the country and we spoke about that. People were keen to express their feelings about their connection to the material. They have a lot to tell you about how people worked and lived.

"Our role is to emphasis that these sites are really important to Aboriginal people.

"We need to ensure this doesn't happen again.."

Land council executive officer Sandy Hodge said the council's purpose was to protect and preserve Wimmera-Mallee cultural heritage.

Mr Hodge said the the disturbed area was part of a larger occupation site that had a large number of quartz tools.

He said the council had a good working relationships with Mitchell Water, GWMWater and other contractors.

He said Barengi Gadjin and GWMWater representatives discussed options for pipeline works to continue in the area while protecting cultural values.

GWMWater ceased work on supply systems three and four when the site was disturbed last week. Work is delayed until Aboriginal Affairs Victoria and the land council approve a cultural heritage management plan.
