Waratahs coach Dan McKellar is confident star duo Joseph-Aukuo Suaalii and Jake Gordon will be right for round one despite injury concerns.
Suaalii (knee) did not feature in the 36-all draw with the ACT Brumbies after initially being named at fullback.

Meanwhile, Gordon (back) lasted just minutes into the game and looked troubled by the knock as he stood on the sidelines for the rest of the game.
"(Suaalii) is a minor issue. He just pulled up a little bit sore and it's a trial game so don't need to risk him," McKellar said post-game.
"We're hoping that he'll train Wednesday.
"(Jake) just jammed up his back, so nothing major. He's just sore through his lower back so he'll turn around quickly."
The Waratahs rolled out ten Wallabies in the starting XV but the Brumbies were up for the challenge as Luke Reimer got the opener from close, followed by Ollie Sapsford.
It was Suaalii and Gordon's replacements that proved the spark as Darby Lancaster crossed in the corner after nice work from the backline.
Jack Grant gave them the lead with one of his first touches after replacing Gordon, collecting a freak offload from Max Jorgensen.
Liam Bowron responded for the ACT side, only for Andrew Kellaway to glide over for a well-deserved try for a 21-19 half-time lead.
Darby Lancaster and Triston Reilly’s tries were answered by impressive flyhalf Declan Meredith and centre Austin Anderson as the Brumbies kept fighting.
Anderson turned provider for Ryan Lonergan to start the final quarter, giving the ACT side their first lead of the game briefly as Felex Kalapu’s late try with seven minutes left levelled the scores.
The Waratahs pushed late for a winner, held up over the line once before Stephen Larkham’s side stopped the rolling maul close to full-time.
"It's just good to get a hitout. The reality is most of the boys that play have been with us for two weeks," McKellar said on the match.
"They're always going to be a bit rusty, a little bit clunky, and you saw that.
"It's taken them some time to get some match fitness on board, but it's good to get through.
"The positive is there's some transfer, and nice to come out of injury free."
The Waratahs will head into camp for the next couple of days to finalise their season.
Meanwhile, the ACT Brumbies will turn their focus towards Friday's trial with the Western Force, with their Wallabies contingency expected to be back.
"I was really impressed with both teams. I thought they were really well prepared, the set-piece really well organise," Larkham said.
".Defensively, both teams started the game quite well. Obviously, 36 points is not something either team would be happy with, defensively but I was really impressed with our first 10 minutes.
"...There's a lot to be happy about."
