The Big Penguin Postal Numismatic Cover (PNC), a 2025 "Aussie Big Things 2" release by the Royal Australian Mint and Australia Post, highlights the 2.5-meter fibreglass penguin in Penguin, Tasmania, built in 1975 to honor its penguin colony and fishing heritage. It features a $1 aluminum-bronze coin with the penguin on a coastal path and "Penguin" sign, paired with a stamped envelope in black-and-white against a green backdrop with a road and sunset, celebrating the seaside charm in a legally tender collectible.

Certified by Mint and Post, this PNC blends numismatic and philatelic appeal, showcasing the Big Penguin’s status as a local icon near penguin-parading beaches. The coin’s detailed design contrasts with the envelope’s vivid hues, reflecting the town’s tourism allure. Part of a 10-coin series including the Big Barramundi, only three-per-customer limit, perfect for collectors and nature enthusiasts.
