VIDEO: Highlander in the dock for disgusting air kick
Nabura was sent off for a wild kick as the Waratahs ended a 40-match losing streak for Australian sides over New Zealand franchises.
Not since May 2016 had an Australian side got the better of a trans-Tasman rival, but the Waratahs ended that hoodoo with a six-try drubbing at Allianz Stadium.
The hosts were eight points to the good following a Taqele Naiyaravoro score when Nabura was given his marching orders for a kung-fu style kick to the face of Cam Clarke – as the Highlanders wing caught a high ball.
Aaron Smith was sent to the sin-bin for a deliberate knock-down two minutes later and Naiyaravoro evaded an attempted tackle from Waisake Naholo to dot down for a second time with the Highlanders down to 13 men, Bernard Foley converting to make it 15-0 at the break.
Israel Folau stole the show in the second half in Sydney, claiming a double of his own to reach the 50-try mark in his 83rd Super Rugby match – only Joe Roff and Christian Cullen achieved that tally in fewer games.
Lalakai Foketi and Curtis Rona also went over for the rampant Waratahs, scores from Elliot Dixon and Ash Dixon providing little consolation for the 2015 champions.
However, Nabura's act of foul play left a sour afterttaste.
Nabura has been charged with having contravened Law 9.12: Kicking.
The case is to be considered in the first instance by the SANZAAR foul play review committee, which will take place on Sunday, May 20 – via video-conference.
All SANZAAR disciplinary matters are in the first instance referred to the foul play review committee to provide the option of expediting the judicial process.
For a matter to be dispensed with at this hearing, the person appearing must plead guilty and accept the penalty offered by the foul play review committee.
