The Lions will make the trip to Dubbo for Saturday's round two clash against the Roos, and it's the first time Tremain will play his former club since moving north at the start of the season.

And on his birthday, no less.

"Pretty excited about it actually, it's going to be something new," Tremain said.

"It is my birthday on Saturday, so hopefully the guys don't spoil the day. A win would be very good and we've prepared pretty well so hopefully we can get across the line, especially on my birthday."

But birthday or not, the pressure will be on for Tremain to perform well against his old club.

The hooker will be focusing on his own game, and keeping up his intensity throughout.

"My personal thing will be just to get the scrums and line outs right for a start and then hopefully try and have a good ball running game."

"They're my main three focus points, and just to try and keep the intensity up in my game, which could be hard in this heat."

It's the heat that he hopes might work in the Roos' favour.

"I think hopefully we can bring an intensity that City can't handle and hopefully the weather's a bit warm for them, so puts them off their game."

He's also hoping for some big support at the ground.

"I am hoping that there'll be a lot of Dubbo people barracking for me now, because it will be a different clash."

"I think that there will be some Orange supporters hoping I do well - hoping I lose but still hoping I do well."

As for the rest of the side, the Roos' forwards, and ball control will be the keys to a win.

"I think for us our forward pack will be our strongest points so hopefully we can keep it in the forwards."

"We've been trying to get our set piece really strong, I think [it's] our focus all year, but in saying that just controlling the ball well."

"I think if you can hold onto the ball the longest I think you've got a good shot of winning most games."

Elias Kinscher will be a key player to watch on Saturday, with Tremain tipping him to be "one of the standout players on the park", after a big game last week.

Newcomer Benn Wright will also be making the step up into first grade, and Tremain said he will also be one to watch.

"Last week his scrummaging was second to none and his strength in the line outs with his lifting was just superb."

"Hopefully he can bring a dominant scrum to Orange City which is what we sort of need and what we're aiming for."

As for Orange City, Tremain has the inside knowledge, and he said the Roos can't afford to underestimate the visitors.

"I think Orange City's backline will be pretty strong. In saying that they will be strong across the park but I think their fullback and wingers will be pretty strong."

"Just to respect them and not give them much room - take away the space."

"I've played there and I know they're a well-drilled unit and they play high intensity, so try and stick with them and try to shutdown their opportunities early."

And he knows the Lions won't hold anything back when it comes to their former teammate.

"They'll come at me pretty hard, I think."

"There'll be a lot of niggles and back chat and stuff like that but I think it's all in good fun... hopefully."

Kick-off is at 3.15pm on Saturday at Victoria Park No. 1 Oval.
