For 125 years the Royal Australian Navy has stood as Australia’s shield at sea — a constant presence through peace and conflict since Federation in 1901. This official Postal Medallion Cover marks that milestone with a striking zinc-alloy medallion that carries the Navy’s enduring values of Courage, Respect, Integrity, Excellence and Service around the official crest.

Limited to just 1,500 individually numbered covers and featuring commemorative Australia Post stamps, this release is a respectful and collectable tribute to the men and women who have served under the White Ensign for more than a century.
