From 2004 to 2012, Snowy Hydro Pty Limited conducted a cloud seeding trial in the Snowy Mountains to understand whether cloud seeding can increase snowfall in this area.
During this period, the Snowy Mountains Cloud Seeding Trial Act 2004 (the Act) required the Natural Resources Commission (the Commission) to supervise authorised cloud seeding trial operations and report on the environmental impacts of those operations to the relevant Ministers.
The Commission completed five reviews of the trial in 2005, 2007, 2009, 2010 and 2012 (see reports below).
In September 2012, the Government announced that the trial would end and cloud seeding would become fully operational. It made legislative changes, including requirements for Snowy Hydro to carry out cloud seeding operations in accordance with an environmental management plan approved by the relevant Ministers, and review of cloud seeding operations by the Environment Protection Authority.
