After last Friday night's win, Parish says the side has trained really well.
"The boys are pretty confident, we played well for the majority of the last game and had a good win from it," he said.
"But we're looking to take more of our opportunities - we created a few but didn't quite finish them off."
"In saying that, we were able to score a few good tries and hang in there late in the match and score a good try to win the match. If we can play some good footy and hold the ball tonight, then I think we can win the game."
Parish says Jarryd Hayne was a welcome return to the side, especially for fullback Jake Mullaney.
"I think Jarryd helped everyone in the team, but particularly Jake," he said.
"It was no coincidence that was his best game of the year, and Jarryd and Luke Kelly put him into some great holes and he ran into some great gaps."
Looking at the Broncos side for tonight's clash, Parish says losing Justin Hodges to injury is a big blow.
"Justin is a very good player, an Origin player - but they've certainly got some other dangerous players there," he said.
"Corey Parker is a very underrated player in their pack and Ben Hannant is slowly finding form. They've got a good team, and Josh Hoffman at the back running a lot of metres."
Parish says the grinding style of football from the Broncos will put a lot of pressure on them to hold the ball.
"They're probably not as flamboyant as us; they compete, they charge up their end and bomb away with Scott Prince and others," he said.
"They chase hard - Reed and Gillett are good in the air. They don't throw as much at you as other teams, but they complete and put points on by building pressure."
