White played in the John I Dent Cup grand final in 2010, kicking a last minute penalty for Queanbeyan to win 30-28 to deny Vikings a fourth grand final victory in a row. In 2011 he joined the Eastwood club in Sydney, playing halfback in their near perfect season, in which they lost only one competition game on the way to defeating Sydney University in the grand final. Nic achieved the rare feat of a hat trick of tries in a finals match in the previous week's final against Randwick, completing his feat in the first 10 minutes of the game. White made his Brumbies debut during the
2011 Super Rugby season against the
Reds in
Brisbane. He started 2012 as the starting halfback for the Brumbies as they just failed by a point to make the finals after a poor 2011 season. In 2013 at the age of 23 he was named as the twelfth player to captain the Brumbies when they played the Melbourne Rebels in a Super Rugby game. The Brumbies made the Super Rugby final in 2013 but after an arduous travel schedule, which included beating the
Bulls in Pretoria, they faded in the closing stages to lose to the
Chiefs in Hamilton. In 2014 they again made the semi-finals, losing to the
Waratahs in Sydney and in 2015 lost in the semi-finals to the
Hurricanes in Wellington. White, alongside teammate
David Pocock, was named vice-captain of the Brumbies for the
2015 Super Rugby season on 15 January 2015. Nonetheless, he would later that year commit to joining French
Top 14 side
Montpellier Hérault by signing a contract. On 16 March 2017, White finalised his move to
Exeter Chiefs in the
English Premiership starting from the 2017-18 season. He later came back to Australia in October 2019 to reunite with the ACT Brumbies. In May 2023, it was revealed that White would embark on a two-year contract with the
Western Force. == International career ==
