The Australian Honour Flag. Towns and districts in Australia which subscribed twice their quota of funds to the Commonwealth Government's Seventh War Loan in 1918 were presented with the Honour Flag with three blue bars and a star. Individual contributors were awarded a certificate known as a House Badge, which featured an illustration of the Honour Flag without the bars and star.
