An anti-whaling campaign ship says it's intercepted a Japanese whaling ship operating in Antarctic waters.
Paul Watson, the captain of the Sea Shepherd Conservation Society's ship, the Steve Irwin, says his crew found the Yushin Maru 2 off the AdÃ©lie Coast.
He says the ship was operating in Australia's Antarctic waters and claimed it had also been working in French territorial waters.
Now the Japanese fleet has been detected, Captain Watson says his ship will do its utmost to stop whales being hunted.
He says if they can't board the Yushin Maru 2, they'll try to bombard it.
Captain Watson says they will use a non-toxic, biodegradable, organic form of chemical warfare which is rotten butter and methyl cellulose.
He says they are food grade products but they smell awful and make everything very slippery.
The ABC reports that Captain Watson wants the federal government to take action against the whaling fleet.
