Japan has rejected claims this year's whale hunt in the Southern Ocean is over, despite the suspension of its fishing and refuelling activities.
Japan's Consul-General in Melbourne, Hidenobu Sobashima, has told Radio Australia's Asia Pacific program his country has not decided when it will resume whaling this season.
"What was decided was a temporary suspension of refuelling, not more than that, not less than that," he said.
Mr Sobashima says whaling activities have been put to an end for the "time being" only.
The whaling fleet has been forced to suspend fishing and refuelling after a collision between the Nisshin Maru and two Sea Shepherd vessels.
Mr Sobashima has also hit out at Sea Shepherd for reckless behaviour at sea.
"What Sea Shepherd is doing endangers the life and property of the crew of the vessels and also endangers the safe navigation of the sea," he said.
Sea Shepherd says with so little of the whaling season remaining, Japan's hunt is over.
Bob Brown, Sea Shepherd's director, says the whaling fleet might have only a few weeks remaining to complete its hunt.
"Our experience, Sea Shepherd Australia's experience, is at this stage of the summer, with the days getting shorter and the winter closing in, whaling is fast drawing to the end as a possibility for the Japanese killer fleets," he said.
Sea Shepherd claimed victory after Japan temporarily suspended its annual whale hunt in the Southern Ocean.
On Wednesday the anti-whaling group claimed two of its boats, the Steve Irwin and the Bob Barker, were rammed by a Japanese ship in Australian Antarctic waters.
It said the attacks happened after they were ordered to leave the area by one of the boats in the Japanese whaling fleet.
Japan's fisheries agency has denied those reports, but confirmed that one of its factory ships, the Nisshin Maru, rammed two boats belonging to Sea Shepherd.
However, it said the clashes happened after activists came too close to a Japanese vessel which was refuelling.
Japan's Institute of Cetacean Research has announced it has stopped work for the time being because it is too difficult to refuel.
