Sealark Property

Sealark Pty Ltd owns substantial parcels of land in the Shoalhaven Region of the NSW South Coast. It is the environmental protection and property development company of the Halloran Trust. Approximately 2,454 hectares (89%) of Sealark’s land is subject to BioBank agreements or is allocated for conservation and 306 hectares (11%) of Sealark’s land is proposed for long term development for housing and other community purposes. The Halloran Trust exists solely for charitable purposes and was established in 2012 by the late Warren Halloran to reflect his vision for high quality development and conservation.

Warren was an interested supporter of and generous benefactor to many interests in the Shoalhaven. In 2015 Warren was appointed a Member of the Order of Australia (AM). The citation of the award is “For significant service to the Shoalhaven community through philanthropic support for maritime, educational, arts, and conservation organisations.”

The Halloran Trust (ABN 33 445 017 500) is a charity registered with the Australian Charities and Not-for-profits Commission (ACNC). Details, including contact details and the names of the “Responsible People” are available on the ACNC website.
