Robinson was given the kicking duties in the absence of Wallabies five-eighth Bernard Foley through concussion.
Clearly there’s some areas in our game that we need to improve in terms of building pressure, putting phases on.
The former NRL back produced a near-perfect kicking display as NSW came back from a four-point deficit at the break to score 10 unanswered points.
He landed four penalties and converted Will Skelton’s 44th minute try, his only miss of the match coming from a penalty attempt right on the siren.
The Force had the consolation of picking up a bonus point from the game which was played in wet and slippery conditions at Allianz Stadium.
All their points came from former NSW player Jono Lance, who got their only try following good work from No 8 Richard Hardwick and halfback Ryan Louwrens close to the Tahs line.
That came while the Waratahs were down to 14 men, with Sekope Kepu having been sin-binned.
In the eight minutes between Kepu’s return and half-time Lance added two penalties to see his side go into the break 14-9 ahead.
The visitors were indisciplined early on, conceding five penalties in the first 12 minutes. Robinson sent the first through the uprights in the opening minute, and added another soon afterwards to have NSW six points up.
Skelton regained the lead for the Waratahs early in the second half when he bumped off Curtis Rona and crashed over to score, as NSW quickly took a penalty close to the Force line.
Coach Daryl Gibson was pleased with some of his players, but not satisfied with the overall performance.
“We could have easily dropped that game tonight, it’s really pleasing that we stuck in there and ground it out,” he said.
“We got the result. Clearly there’s some areas in our game that we need to improve in terms of building pressure, putting phases on.”
