Greens Senator for South Australia Robert Simms says BP should cease its preparations to drill for oil and gas in waters off SA.

It was reported today that BP Australia is currently building a supply base in Port Adelaide to serve its desired exploration campaign for oil and gas.

"It's inappropriate and arrogant for BP to be proceeding with the construction of a supply base when they have not been given permission to conduct the drilling," said Senator Simms.

The Australian Greens will explore avenues to appeal a decision allowing seismic testing off the coast of Kangaroo Island.

The application by Canadian company Bight Petroleum to conduct seismic testing as a precursor to oil and gas drilling has been approved by NOPSEMA, despite strong community opposition.

Australian Greens Senator for South Australia Penny Wright said she would explore avenues for appeal when further documents are released.

Kangaroo Island's community and tourism industry will be jeopardised if federal Environment Minister Greg Hunt fails to block seismic testing off the coast, says Australian Greens Senator for South Australia Penny Wright.

Senator Wright, who has been working with the Kangaroo Island community since the exploration was first mooted two years ago, said Bight Petroleum's report on community concerns was completely inadequate and showed disregard for South Australians.

The Weatherill Government must refuse to adopt Prime Minister Abbott's plan to gut national environment protection at COAG tomorrow, says Australian Greens Senator for South Australia Senator Penny Wright.

Federal Labor representatives voted with the Greens yesterday to call on the Weatherill Government to reject the move.

"Tony Abbott wants to take away a 30-year-old federal veto power to protect our most precious wildlife and wilderness," South Australian Greens Senator, Penny Wright, said.
