In his first season with Balmain, he was the League's top try-scorer. At the end of his debut season with Balmain in 1978 in which he scored 24 tries, Larry Corowa was selected as a member of the 1978 Kangaroo tour, though he did not play a test on tour. He made his test debut for Australia during the 1979 Ashes series against the touring Great Britain Lions at Lang Park in Brisbane with the Kangaroos winning 35–0. He played in the first two games of the series for his only test appearances, scoring a try on debut at Lang Park. Nicknamed "The Black Flash", Corowa was considered during his time with Balmain to be 'the fastest player in the game' not only in Australia but the rest of the rugby league world. Larry Corowa is listed on the Australian Players Register as Kangaroo No. 516.[4]
After retiring from First Grade league following the 1983 season, Corowa moved to the Gold Coast and became involved with the Gold Coast Seagulls. In 1991, at the age of 34 and after eight years in retirement, he played two games for the Seagulls, scoring a single try to take his overall tally to 65 tries from 100 games before retiring permanently.
