The Japanese icebreaker Shirase (AGB-5003) and the tugboat Svitzer Albatross in Cockburn Sound, Western Australia. The ship was in the southern part of the sound, between Garden Island and the Kwinana Grain Terminal. The Shirase eventually went to moor at HMAS Stirling, but I did not watch to see whether the Svitzer Albatross assisted with this.
