Fullback Kurtley Beale helped the Waratahs beat the Blues 33-12 in a warm-up match in Sydney on Friday.
Beale scored his first try since returning to the Sydney-based side when he went over following a 5m scrum. WIll Skelton then scored a second for the Waratahs, and Beale's conversion gave them a 14-0 lead at half-time.
Bernard Foley opened the scoring in the second half, going over for a try that he converted.
The Blues finally hit back through a chip-and-chase try from Jordan Manihera. The Aucklanders' fortune was changing, as Charles Piutau pounced on a loose ball and scored under the posts, and the successful conversion made it 21-12 with 30 minutes to go.
But the Waratahs then scored two tries through Stephen Hoiles and Alofa Alofa to make the game safe.
Waratahs – Tries: Kurtley Beale, Will Skelton, Bernard Foley, Stephen Hoiles, Alofa Alofa. Conversions: Foley (3), Beale.
