Members of the South West Aboriginal Medical Service recently marched on its headquarters to demand the dissolution of its board amidst ongoing turmoil in the organisation.

Police were called to the SWAMS headquarters in Bunbury in WA's south west last Wednesday after members staged a protest and held a meeting in the building's lobby.

Earlier, a Noongar man living in the region who wished to remain anonymous told National Indigenous Times "Our community is missing out" because of the alleged turmoil in the SWAMS.

"We have been given a significant grant for our community. The board stood down the CEO… We just want an outcome so the community can get services," he said.

"The community is going to suffer. It has caused a lot of division in the community as well.

"Services have been interrupted, the wait times extended, doctors are talking about leaving, our old people are getting nervous. It needs to be raised so they can sort it out."

National Indigenous Times sent questions to SWAMS before last Wednesday's protest, asking why former CEO Lesley Nelson was dismissed, what impact has there been on services, if any staff have left, and when services will return to normal. The Service provided no answers.

SWAMS member and nurse Donna Turvey told National Indigenous Times the SWAMS board is not following proper processes.

"The second month before the AGM was for Expressions of Interest to sit on the board, and the month before was the selection of who the board members were going to be - put to the board, and they were to meet on it and then arrange to show them at the AGM," she said.

"Well, they did not follow that process at all."

She named three board members and alleged they were "unconstitutional and unlawful, member directors".

"They're standing down people without process."

Last Wednesday about two dozen SWAMS members, including one recently dismissed director, were blocked from entering its offices.

The group held an unofficial meeting in the lobby, and voted to dissolve the board and appoint Elder delegate David Williams as an interim director.

The ABC reports that Mr Williams, who drove from Katanning for the meeting, said it was disrespectful that the members were not allowed inside.

"Some of the Elders are over 80 years of age," he told the national broadcaster.

"They've fought a long time for the improvement of our people and services, and you haven't even got the respect to allow them to go in, sit down and voice their opinions.

"It's totally disrespectful and it's not Noongar culture."

Police eventually disbanded the meeting. No charges were laid.

The SWAMS website lists three directors, down from six in May: Phillip Ugle, Ernie Hill, and Janine Williams.

Ms Nelson, the former chief executive, was dismissed earlier this year having led the service for a decade.

"These guys are destroying everything that Leslie Nelson, who was the CEO before they've stood her down without cause, and everything that she's done for the company for the last 10 years, they're undoing now, and we may even miss out on the promised $40 million for the new health hub that was supposed to be started in October this year," Ms Turvey said.

"It's an absolute mess. And everything that has been achieved over this last 10 years, man, they are destroying."

Another SWAMS member, Lynette Narkle, told the ABC there was confusion around what had happened with Ms Nelson and some of the deposed directors.

"We're concerned about the lack of transparency," she said.

Ms Turvey told the ABC the removal of several directors was supported by at least 60 members, which she said was above the five5 per cent required to call a general meeting on the issue.

The National Disability Insurance Scheme (NDIS) Commission issued a compliance notice to SWAMS in March, alleging it had breached conditions of its registration with the scheme, the ABC reports.

The notice said the corporation had failed to commence a mid-term audit within 18 months of becoming registered.

In a statement on SWAMS's Facebook page, chair Phillip Ugle acknowledged concerns around the charity's governance but said they were unfounded.

"The SWAMS board wishes to reassure our members, clients, and community that we have acted in accordance with all legislative, governance, and constitutional requirements, and have continued to seek independent legal advice throughout this process," he said.

Mr Ugle said SWAMS services had not been impacted.

A WA government spokesperson told the ABC it had no powers to intervene due to SWAMS being constituted federally under the Australian Securities and Investments Commission (ASIC).

The Federal Department of Health, Disability and Ageing told the ABC it was aware of the current governance issues at SWAMS.

"Matters relating to the composition and conduct of an incorporated organisation's board are primarily the responsibility of its members and the relevant regulatory authority — in this case, the Australian Securities and Investments Commission," a spokesperson said.

"The department actively monitors issues as needed to ensure that funded services are delivered in line with the obligations of their grant agreements. Where those obligations are not met, the department may consider taking action."
