Nicknamed 'Horse', Niebling was a constant thorn in the side of New South Walesforwards during the titanic State of Origin clashes of the early 1980s. His career in the State of Origin arena saw him make 9 appearances while playing for Brisbane Valleys and Redcliffe.
Niebling made his Test début in the second row against Great Britain in 1984, and ultimately played in all three matches of Australia's Ashes whitewash.
Named Redcliffe's player of the season and co-winner of the Brisbane Rugby League premiership's Rothmans Medal in 1986, Niebling toured with the unbeaten Kangaroos and played in 10 matches including all five Tests. The last of Niebling's 13 Test appearances was in Australia's 13-6 loss to New Zealand at Lang Park in 1987. Niebling captained Redcliffe in the 1987 Woolies pre-season, but missed most of the regular season due to injury. He was succeeded as captain of the side by Steve Bleakley, but returned to play in Redcliffe's Grand Final loss to Past Brothers.
