The Big Prawn Postal Numismatic Cover (PNC), a 2025 "Aussie Big Things 2" release by the Royal Australian Mint and Australia Post, honors the 18-foot fiberglass prawn at Exmouth’s Tourist Centre, built in 2005 by Brian Paskins to attract visitors to Ningaloo Reef. It includes a $1 aluminum-bronze coin with a curved prawn by palm trees and a "Tek Rio Kraur" sign, paired with a stamped envelope featuring the prawn on a signpost near a lighthouse and waves under a vibrant sky, celebrating Exmouth’s marine charm in a legally tender collectible.

Certified by Mint and Post, this PNC blends numismatic and philatelic appeal, reflecting Exmouth’s coastal allure and cyclone-resilient spirit, enhanced by its 2020 refurbishment. The coin’s detailed prawn contrasts with the envelope’s teal-blue and orange seascape, part of a 10-coin series including the Big Wheelbarrow, making it a perfect memento for collectors and ocean enthusiasts.
