This postal numismatic cover commemorates the Australian Big Things as an integral part of Collecting Month 2023, prominently showcasing the Giant Koala $1 coin.

Positioned in the western Victorian town of Dadswells Bridge, approximately 20 kilometers south-east of Horsham, stands the Giant Koala. Crafted in 1989 by the skilled Dutch sculptor Ben Van Zetten, this impressive structure combines bronze and fibreglass elements, supported by a robust steel frame. With dimensions spanning 14 meters in height and eight meters in width, this monumental creation transcends mere sculpture to resemble a substantial edifice. Notably, its interior, accessible via the Koala's front forearms, serves as a home to a souvenir and gift shop.
