The Big Wheelbarrow Postal Numismatic Cover (PNC), a 2025 "Aussie Big Things 2" release by the Royal Australian Mint and Australia Post, highlights the oversized yellow wheelbarrow in Wedgefield, Port Hedland, a mining hub known for iron ore exports. It features a $1 aluminum-bronze coin with the wheelbarrow loaded with ore, a biplane, and "Welcome to Wedgefield" sign, paired with a stamped envelope showcasing the sunny barrow under a blue sky, capturing the Pilbara’s rugged charm in a legally tender collectible.

Certified by Mint and Post, this PNC blends numismatic and philatelic appeal, nodding to the 1960s wheelbarrow race tied to the Black Rocks Stakes, halted in 2010. The coin’s detailed design contrasts with the envelope’s vibrant coastal-industrial hues, reflecting the region’s mining legacy. Part of a 10-coin series including the Big Barramundi, it’s a perfect memento for history and travel enthusiasts.
