The Victoria Aboriginal Affairs Victoria website Cultural Heritage Legislation page provides the following summary of legislation covering Aboriginal heritage in Victoria
"The protection of Aboriginal heritage in Victoria is dealt with under a unique legislative structure that includes both a Commonwealth and State Act. The interrelationship between the Commonwealth and State legislation is complex and uncertain in effect. However, where there is a conflict, the Commonwealth legislation takes precedence over the State legislation.The Schedule to Part IIA of this Act lists Victoria's local Aboriginal 'communities' with responsibilities under the Act. Each community's geographical area is defined in the legislation. Local Aboriginal communities represent various Aboriginal group interests in the region and is recognised under the Commonwealth Act as having responsibility for Aboriginal cultural heritage in its defined area. Where there is not a functioning local Aboriginal organisation, powers revert to the Minister. "
New legislation will be proclaimed on the 28th of May. Details and a link will be provided here when available. The current act is available at the following link.
