HMAS Sirius (O 266) (formerly MT Delos) was a commercial tanker purchased by the Royal Australian Navy and converted into a fleet replenishment vessel to replace HMAS Westralia. She was named in honour of HMS Sirius of the First Fleet. Launched in South Korea on 2004, and converted in Western Australia, Sirius was commissioned in 2006; three years before a purpose-built vessel would have been built, and at half the cost. The tanker was decommissioned in 2021 and subsequently scrapped.
