As King Charles III turns 75, Australia Post is commemorating the new head of the Commonwealth with three special edition stamps.
Two of the stamps will mark the king's birthday on November 14, while a third will highlight his coronation.
One stamp features a young Charles in a black-and-white portrait during a journey to Sydney in 1966.

A second, from 2018, shows the king seated at his desk, while the third pictures him in his crown.
It's the first time Charles III has appeared on an Australia Post stamp since his coronation.
"The collection encapsulates the essence of King Charles III's legacy, embodying his continued commitment to tradition and progress," Australia Post said in a media release.
The King Charles III stamp collection is on sale now at participating post offices, via mail order on 1800 331 794 and online while stocks last.
