The Big Barramundi Postal Numismatic Cover (PNC), a 2025 "Aussie Big Things 2" release by the Royal Australian Mint and Australia Post, showcases the 10-meter fibreglass barramundi in Normanton, Queensland, built in 1998 to attract anglers. It includes a $1 aluminum-bronze coin with a leaping fish over a river scene and "Normanton" sign, paired with a stamped envelope in blue and orange hues depicting a sunset sky and road, celebrating the outback fishing legacy in a legally tender collectible.

Authenticated by Mint and Post, this PNC merges numismatic and philatelic value, highlighting the Big Barramundi’s status as a Normanton fishing icon near the Norman River. The coin’s detailed design contrasts with the envelope’s vibrant landscape, reflecting the region’s tourism appeal. Part of a 10-coin series including the Big Prawn, it’s priced at $20 AUD with a three-per-customer limit, ideal for collectors and fishing fans.
