The Waratahs revived their Super Rugby season with a 51-27 win over the Australian conference leaders the Rebels at the Allianz Stadium.

They scored five unanswered tries within 20 minutes in the second half to end the Rebels unbeaten start to their 2018 campaign.

The victory for the Waratahs comes after two consecutive defeats in their previous matches. They overcame a 17 point deficit with a spectacular second half try-scoring.

The home side didn’t start well and defeat looked very much on the cards.

This after the Rebels charged to a 20-three lead through first half tries to Tom English, Amanaki Mafi and Jack Maddocks.

However, a try by Lalakai Foketi before the half time break was the inspiration they needed for a remarkable comeback.

The hosts then came out after the interval and produced their best half of the season.

In a 20-minute domination, they ran riot as Rob Simmons, Mitch Short, Bryce Hegarty and Taqele Naiyaravoro crossed the line.

Bernard Foley converted all four of those tries and added a penalty as they went 41-20 up.

The Rebels pulled a try back, but the Waratahs added 10 more points with Naiyaravoro completing the half with another try in the final minute of the game.
