Waratahs back Andrew Kellaway has signed with UK premiership side Northampton Saints for the 2018-19 season.
Kellaway, whose NSW contract finishes at the end of 2018, has played all his Super Rugby with the Waratahs, and came through their U20s ranks.
Kellaway was a U20s star, setting a try-scoring record in the 2014 World Rugby U20s, but hasn't been able to replicate that form at Super Rugby.
He had a breakout year in 2016, invited on the Wallabies' Spring Tour, but struggled with consistency in 2017 and 2018, with a leg injury suffered in club rugby also hindering his chances this season.
The Waratahs have a glut of outside backs, with Kellaway out of the starting frame in 2018, behind players including Cam Clark and Alex Newsome.
The Saints announced their new addition on Tuesday night, with Kellaway saying it was an opportunity to good to pass up.
"Getting the chance to join Northampton Saints was a really exciting opportunity for me and one I jumped at,” he said.
“The club has a great history of success and their ambition is clear to see with Chris Boyd and the new coaching set-up coming in this summer, as well as the number of top-quality players also joining the club next year.
“I’m excited to get going and to pull on the black, green and gold jersey for the first time.”
Kellaway will join Taqele Naiyaravoro at the Saints, after the mammoth winger inked a deal with the club earlier this year.
