Japan has said it will go ahead with its annual whale hunt.
Last year the country cut short the whaling season because of protests from anti-whaling campaigners.
Commerical whaling - hunting whales for money - has been banned for 25 years, but Japan still catches 1,000 whales a year for scientific research.
But some people say the hunt is commercial whaling in another form, and Australia is taking Japan to an international court to try to stop it.
Japan says that extra ships will escort the whale hunting fleet to try and protect the group.
The whaling fleet usually sails south to the Antarctic in the autumn each year and returns the following spring.
Last year the group returned early saying it was concerned for its safety, after an anti-whaling group followed the fleet south.
The group, Sea Shepherd, has pledged to follow the fleet again this year and try and stop its hunt.
