Andrew Gerard Slack (born 24 September 1955 in Brisbane) is an Australian former state and national representative rugby union player who captained the Wallabies in 19 Test matches in between 1984 and 1987.
[citation needed] He played his club rugby with Brisbane Souths and made his Queensland state debut against a Combined Services side, as a five-eighth at age 19 in 1975 before switching to centre for the rest of his career.
He returned for the 81/82 tour to the UK where Australia's gifted side lost three out of their four test matches, but Slack was able to register his first two tries against Wales and Scotland respectively.
The decision turned out to be a good one and Slack led the Wallabies to a momentous Grand Slam against the Home Nations on the autumn tour of the UK.
"[citation needed] He temporarily retired from the international game in 1985 but returned the year after to lead Australia to an even greater achievement than the Grand Slam – a series win on New Zealand soil, which put any doubt to rest over the Wallabies claims to being a world power.
Slack's career ended on a low note when Australia were beaten in the World Cup semi-final against France, and his last game came in the 3/4 play-off defeat by Wales.
He is one of six captains to lead his side to a test series win on New Zealand soil, along with Philip J. Nel (1937 Springboks), Trevor Allan (1949 Australia), John Dawes (1971 British Lions), Philippe Saint-André (1994 France) and Johnny Sexton (2022 Ireland).
