Heidke grew up in Bundaberg in the Wide Bay – Burnett region of Queensland where he played rugby union.
[1] He played for Souths Magpies and represented for Queensland against the professional New Zealand All Golds in June 1908 when that team was on its return from the "rebel" tour to England.
Heidke and the other players who breached the amateur code of principal were consequently suspended for life by the Queensland Rugby Union.
[1]In those early days of domestic Tests the make up of the side was dependent on whether the game was to be played in Brisbane or Sydney.
To save on travel costs and to engender local support the Australian representative sides were often selected with a major hometown bias.
