Norfolk Island (Australia) on 21 November 1989 issued a set of three First Day Cover stamps commemorating Radio Australia's 50th anniversary (1939-1989).
The stamps featured:
41c - Inaugural announcer John Royle
65c - Radio Australia coverage
$1.10 - Jacko the laughing kookaburra
Radio Australia opened its broadcasts with the melody "Waltzing Matilda" and the song of the Kookaburra bird, hence the cachet and stamp design. Its programmes targeted the Pacific and Oceania, but we're just as popular throughout the English-speaking world.
