The two-metre-high Big Blue Heeler (called Big Blue) sits obediently on a plinth at Muswellbrook in the Upper Hunter Region of New South Wales, 241 kilometres north of Sydney. The bronze sculpture by Brett “Mon” Garling was made in 2001 to celebrate the famous Australian Cattle Dog, or Blue Heeler, a cross between the Australian Dingo and the Northumberland Blue Merle, first bred at Dartbrook, 12 kilometres north of Muswellbrook.

The postage stamp used in this coin and minisheet collection features the Australian Cattle Dog, or Blue Heeler, from the stamp issue, Working Dogs released 10 June 2008.
