In September 1982 the Australian rugby league Kangaroos landed in Britain. When they left at the end of November they were acclaimed as the Invincibles, the greatest rugby league touring team ever. Not since the 1905 All Black rugby union tourists had any visiting sports team had such an impact on Britain.
