The FPV ''Westra''
was laid up ready for disposal in 2003 when Sea Shepherd purchased her in November 2006 and renamed her ''Robert Hunter''.
2007
In February 2007, ''Robert Hunter'' joined ''Farley Mowat'' in order to prevent the Japanese whaling vessel ''Nisshin Maru'' from hunting in an action Sea Shepherd called Operation Leviathan. Sea Shepherd members threw bottles of foul-smelling

onto the decks of the ''Nisshin Maru''. The Japanese say three members of the whaler were injured in the attack. ''Robert Hunter'' and ''Farley Mowat'' obstructed the path of the whaling ship, and ''Robert Hunter'' and ''Kaiko Maru'' collided with each other. One Japanese official accused the Sea Shepherd organisation of behaving "like pirates". ''Robert Hunter'' sustained a 3-foot gash in the hull above the waterline at the stern of the ship.
''Steve Irwin'' has also participated in "Operation Migaloo" (named after

, were detained by crew of ''Yūshin Maru No. 2''.

Sea Shepherd claimed that the two had been kidnapped and tied to the radar mast for several hours with ropes and
zip ties. Potts and Lane, however, later stated that they were tied for only fifteen minutes to the side of the ship and a couple of minutes to the radio mast before being taken below deck.
Glenn Inwood, a spokesperson for the whalers from the
Institute of Cetacean Research (ICR), said that the activists were being held in an unlocked office, but were being guarded. In another statement, they stated that the action of boarding their vehicle was illegal and that the men were being held pending decisions on their future.
On January 16 the ICR issued a statement claiming that the protesters had thrown canisters of acid on board the ship and attempted to damage property. They also denied claims that the men had been assaulted and tied to the ship's mast.
Hideki Moronuki further stated that "The ICR (Institute of Cetacean Research) is ready to release the two Conservationists provided that full security can be secured for our research vessel. Sea Shepherd is a very violent organisation." In a letter faxed to ''Steve Irwin'', the ICR stated that part of the handover conditions include that Sea Shepherd "must not take any violent action or video/photo shooting activities against us." The acid in question was, according to Sea Shepherd, butyric acid, which was used not to damage the ship itself but to render the work-deck unusable due to its foul and long-lasting smell.
On January 17, the Australian customs ship started preparation to transfer the two men held on the whaling vessel. On the morning of January 18, the two men were safely transferred to the . After an investigation by the

, no criminal action was taken against the conservationists.
Both sides accused the other of terrorism during the incident. The ICR called the butyric acid attack on ''Yūshin Maru No. 2'' an "inhumane terrorist attack" and called on the Australian Government to seize the ''Steve Irwin''. Conversely, ''Steve Irwin'' 1st Officer Peter Brown stated that "the Institute of Cetacean Research is acting like a terrorist organisation
..Here they are taking hostages and making demands. Our policy is that we don't respond to terrorist demands."
Following the March 3 clashes between Sea Shepherd members aboard ''Steve Irwin'' and Japanese whalers, the Dutch government announced that it was investigating the incident as the vessel sails under the Dutch flag.
2009
On February 6, ''Steve Irwin'' collided with the vessel ''Yūshin Maru No. 2'' () and later with the vessel ''Yūshin Maru No. 3'' () while they were whaling in the Southern Ocean. The Japanese-based
Institute of Cetacean Research claimed that MY ''Steve Irwin'' deliberately turned into the stern side of the vessel ''Yūshin Maru No. 3'' to ram her. Video footage of the incident was later released by the institute showing the incident. ''Steve Irwin''s operator Paul Watson denied the ramming, saying "They weren't rammed, two vessels collided—the ''Yushin Maru 3'' and the ''Steve Irwin'' when they shot in front of us to transfer whale."
For the next year, the ship was drydocked in Brisbane while repairs to the hull and other alterations could be made. Included in these renovations was the installation of ''Steve Irwin''s own water cannon for use in campaigns. After three days, a suspected Japanese-chartered aircraft located the ''Steve Irwin'' en route to the Southern Ocean and instructed the to observe the movements of the vessel. Heavy swells barred the Delta from reaching the vessel, and, upon arrival, a Japanese
LRAD was used against the helicopter which forced it to stand down. For the next two weeks, ''Shōnan Maru 2'' continued to observe ''Steve Irwin'', despite continued attempts by the ship to lose the tail. Ultimately, ''Steve Irwin'' returned to Australia, where ''Shōnan Maru'' was unable to track her due to a heavy storm, in addition to legal complications.

On February 8, ''Steve Irwin'' joined ''Bob Barker'' in pursuit of ''Nisshin Maru''. Once the two Sea Shepherd vessels had linked up, ''Steve Irwin'' took up position behind ''Nisshin Maru'' to obstruct the factory ships slipway and engaged her with water cannon. On February 15,

In December, ''Steve Irwin'' joined ''Bob Barker'' and ''Brigitte Bardot'' in locating and pursuing the Japanese whaling fleet, which had passed by off the western Australian coast, on the way to the Southern Ocean for whaling operations. A drone surveillance aircraft launched from ''Steve Irwin'' located the whaling fleet some 500 miles off the southwest coast of Australia on December 24. After chasing the fleet for four days, ''Steve Irwin'' had to break off and escort ''Brigitte Bardot'' back to Fremantle, after ''Brigitte Bardot'' was damaged by a
