Former health minister’s adviser joins government-funded provider cohealth
Melissa Arch, a former chief of staff to Victorian Health Minister Mary-Anne Thomas, has joined community health provider cohealth.
Before leaving government in July, Arch attended two meetings with cohealth executives and Thomas about the organisation’s issues, including funding.
In May, while Arch was still in government, the state helped secure a $1.5 million federal bailout for cohealth.
A June independent report identified serious failures at the provider, which serves low-income residents mainly in Collingwood, Fitzroy and Kensington.
A transparency watchdog chief said Arch’s move could create a perceived conflict of interest, while cohealth rejected that suggestion.
Victoria has no general required cooling-off period for senior government staff, apart from some lobbying activities.
Cohealth is recruiting for a new executive role in client participation and partnerships, but the sources do not say what happens next with Arch’s appointment.

Clancy Moore, Transparency International Australia
Moore recommended a minimum three-year cooling-off period for senior public servants, chiefs of staff and ministers.
We always suggest there should be a cooling-off period for senior public servants, chiefs of staff, or ministers particularly to prohibit post-parliamentary employment in lobbying roles. This should be for a minimum of three years to stop unfair influence and access,
