On 5 June 2016, an extreme rainfall event in Tasmania’s Central Highlands resulted in a major flooding that killed three people and caused significant damage to livestock, property and infrastructure. Earlier the same day, Tasmania’s commercial producer of hydroelectricity, Hydro Tasmania, had conducted a cloud seeding operation in the area. Cloud seeding is a form of weather modification
Two days after GE’s first outdoor experiments were conducted in the US, in 1947, the Australian House of Representatives requested the Commonwealth Scientific and Industrial Research Organisation ( ‘CSIRO’)54 to conduct its own research on cloud seeding.
The Rain-Making Control Act 1967 makes cloud seeding a governmental function and
provides immunity from liability
a recent experiment in Queensland was a public/private initiative, involving the American-based company, Weather Modification Inc
It was agreed that any disaster would be dealt similarly as natural bushfires and floods, and that the Crown should not be held liable for damage resulting from weather modification activities
Conclusion: Australia has played a major role in weather modification research and implementation.
