Who is Sealark?

Sealark Pty Limited (Sealark) is a company owned by The Halloran Trust.

Sealark owns approximately 2,760Ha of land between Culburra Beach and Sussex Inlet in the Shoalhaven Local Government Area on the NSW South Coast.

Sealark is responsible for managing its land which includes land set aside for environmental protection and land set aside for property development.

Approximately 2,454 hectares (89%) of Sealark’s land has been voluntarily conserved in accordance with a “Biobank Agreement” with the NSW Minister for the Environment under the Threatened Species Conservation Act 1995, or is proposed for conservation in one form or another.

The balance of the land, approximately 306 hectares or 11%, is proposed for long-term property 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 AM to reflect his vision for environmental conservation and high-quality property development. 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.
