The Australian Jazz Quartet were an Australian-origin jazz ensemble formed in the early 1950s by a group of musicians who relocated to North America, performing within the cool jazz and modern jazz idioms. They developed a chamber-jazz approach that blended vibraphone- and woodwind-led textures with bop-influenced improvisation, evolving through extensive touring in North America and contributing to mid-1950s cross-cultural exchange between Australian and American jazz scenes.
