The first Kangaroo was Arthur Hennessey, as he was the original captain of the side. The rest were added in alphabetical order, then in order of selection. Inclusion in the Kangaroos register denotes a player's selection for a Kangaroos squad and does not necessarily mean an actual full international appearance was made. The year selected represents the first year in which they were called up for international duties and the appearances represent full international matches. New Zealand players who were selected to play for 'Australasian' representative teams are also included.
