Sirius Islands (66°57′S 57°27′E) is a chain of islands in the north part of the Oygarden Group. Mapped by Norwegian cartographers from aerial photos taken by the Lars Christensen Expedition, 1936–37, and called Nordoyane (the north islands). The group was first visited by an ANARE (Australian National Antarctic Research Expeditions) party in 1954; this chain was renamed by Antarctic Names Committee of Australia (ANCA) after the star Sirius which was used for an astrofix in the vicinity.
