ABC Science Online unveils Aussie's Nanotechnology Strategy:

The report states that there is no case for establishing new, nanotechnology-specific regulations to protect human health and the environment, but suggests existing regulations may need adjusting... it recommends that any proposed changes to regulatory frameworks should "not add unnecessary regulatory burden to industry"

I have not read the report and I don't really know in specific Australia's environmental and health legislation so I cannot give any comments. However, the criticism deserve an attention:

Australian Council of Trade Unions occupational health and safety officer, Steve Mullins, supports the establishment of a specific office to oversee nanotechnology. But he criticises the report's failure to recommend the establishment of new regulations specific to nanotechnology.

Georgia Miller of the Friends of the Earth's nanotechnology project also criticises the report. It is unacceptable for the community to be treated like guinea pigs when it comes to the risks associated with nanotechnology," says Miller. She also says the report does not consider developments such as nanotechnology in food, environmental risks, human enhancement, nanbioweaponry or nanobioterrorism.

I'll try to get the report and explain why new laws might be required.
