ALGA established this group to meet the challenges of Australasia’s rapidly changing regulatory landscape on the management of asbestos. It's aim is to provide a stand-alone forum for a range of professions to work collectively on consistent guidelines for regulation. It is also hoping to provide opportunities for practitioners to network, as well as a mechanism for collective industry advocacy focused asbestos related regulation.

The group's aims and objectives are to provide an informed industry group representing a range of stakeholders (consultants, laboratories, lawyers, contractors, regulators, property owners, developers and the community), with the group’s activities aiming to:

  • Promote a better understanding of current guidelines and regulations and the science and policy behind these
  • Promote consistent application of current guidelines and regulations
  • Identify problematic areas of the above and encourage these to be actively addressed in consultation with relevant decision-makers (eg. HACA)
  • Lead to a practical and defensible approach to viably assessing and managing problem sites which has community and regulatory acceptance.

In late 2017 to further pursue the ALGA mission of Australasia to lead the world in the sustainable management of contaminated land and groundwater, the previously known NZ Asbestos Advisory Group and Interest Group Neutralising the Legacy of Asbsestos in Soil was merged into just one interest group addressing Asbestos. This year the committee of volunteers listed below divided into 4 working groups to address the following topics: Australian Regulatory, New Zealand (NZ) Regulatory, Built Environment and Contaminated Sites.
