Michael Hooper has bucked the trend of departing Australian stars by signing a new deal with the Waratahs through to 2018.
The incumbent Wallaby skipper helped the 'Tahs to their maiden Super Rugby title last season and has now extended his contract to keep him in Sydney for a further three years, where he will work with new head coach Daryl Gibson.
"Naturally we’re delighted that Michael has committed to the Waratahs for the next few years, he is an outstanding player, and a very important leader within the team," Gibson said.
"He has been an integral part of the team during his time here, and his role in continuing the legacy of the club will be extremely important – particularly in a year when we will be losing a number of senior players.
"His record on the field speaks for itself, he plays more minutes than nearly everyone and is consistently one of our best players each week – he’s having a strong season this year and will just get better from here."
Hooper hasn't missed a game for the Waratahs this season, and he has missed just 13 minutes total so far in the campaign.
Last year he was named Waratahs Players' Player of the Season for the second straight year after taking over the captaincy from the injured Dave Dennis to lead the title-winning Super Rugby campaign.
