Randall was selected for the Australian team on the 1973 Kangaroo tour, but a broken thumb suffered on tour restricted him to only five minor games and he did not play in a test. He first represented Australia during the 1975 World Cup, playing in the front row in Australia's 36–8 win over New Zealand at Lang Park, scoring a try on debut. He went on to play in 11 internationals for Australia during his career, the last coming in Australia's 13–12 win over Great Britain at the SCG during the 1977 World Cup.
