Sub-Collection: Tasmanian postmarks with a mining or mineral connection.
This 45‑cent Koala definitive from the 1990s is part of Australia Post’s long‑running wildlife series, designed to showcase native fauna in clean photographic layouts. Although not mineral‑themed, the stamp is highly relevant to my collection through its legible Avoca postmark, linking it to a locality with a rich geological and mining history.
