"They are a champion side and will want to bounce back."
However Farah believed NSW had a distinct advantage hosting Origin I at what he hoped would be a sell-out ANZ Stadium.
"Game one is such an important game," he said. "To have it here, a place we love playing at, makes it very special for us and very difficult for Queensland. Hopefully by tomorrow it will be sold out and a very intimidating place."
Statistics back Farah's view.
In the 33 series since the three-game format's introduction in 1982, the team that has won the first instalment has gone on to clinch the title 24 times.
NSW have won the first contest in 11 of their 13 series victories to date.
Farah claimed to be unaware of the problems that have plagued Queensland's Origin camp which lost Daly Cherry-Evans (shoulder) to injury and sweated on the fitness of Greg Inglis (tonsillitis), Billy Slater (shoulder) and Justin Hodges (foot).
However he was glowing about NSW's "perfect" preparation, saying the Blues were buzzing thanks to their new faces.
The enthusiasm of debutant forwards David Klemmer and Josh Jackson has rubbed off on teammates while Andrew Fifita and Mitchell Pearce have been embraced upon their return.
"There is a lot of excitement," he said. "Even guys like Fifita who is back in this arena after a year off and Mitch Pearce [who also missed 2014], they've been great and are just looking forward to it.
"We have had everyone training since day one which I think is important.
"We are confident. We have ticked all the boxes. That's one thing, now we have to get the job done."
