In 1977 Olling made headlines when he became the first rugby league player to admit to taking anabolic steroids.[5] It was a six-week course taken under medical supervision in the off-season and was not illegal at the time.[6] During 1978 he was selected to play for New South Wales against Queensland and then became Kangaroo No. 506[7] when he made his international début against the visiting New Zealand side. At the end of that season Olling was selected to go on the 1978 Kangaroo tour of Great Britain and France, playing in Test matches against both nations. A broken leg reduced the amount of football Olling played in 1980 and he left Sydney.
