This commemorative 27-cent stamp, issued by Australia in 1983, marks the Centenary of St John Ambulance in the country. The design features the Maltese Cross — emblem of the Order of St John — set against a blue gradient background, symbolizing dedication and service. The small heraldic lions between the cross arms highlight the order’s historic British roots and its enduring humanitarian mission. This issue honors 100 years of lifesaving and first aid work carried out by St John volunteers throughout Australia.
