The Star of Gallantry (SG) is a military decoration awarded to personnel of the Australian Defence Force (ADF) and other persons recognised by the Minister for Defence.

[4][5][6] The SG was introduced on 15 January 1991, replacing the Imperial equivalents, (the Distinguished Conduct Medal and the Conspicuous Gallantry Medal Air and Naval), as second level awards to Other Ranks and ratings.

The SG also replaced the Distinguished Service Order, in its role as an award to officers for gallantry.

Recipients of the Star of Gallantry are entitled to use the post-nominal letters "SG".

The Veteran's Entitlements Act 1986 Section 102 specifies that the Repatriation Commission may grant an allowance of A$2.10 per fortnight to veterans, serving members of the Australian Defence Force, and members of Peacekeeping Forces who have been awarded the Star of Gallantry, or other "eligible decorations" specified in Section 102.
