The university side hasn't won a Southern Inland title since defeating Albury in 2012 but have set up a grand rematch with Waratahs on Saturday.

They haven't beaten their crosstown rivals since 2015, including a 52-14 loss in last year's decider plus defeats in all three of their meetings this season.

The latest was a 55-12 thumping in the major semi-final however the first-year skipper believes the side is better placed this time around.

"We're really energised and a lot fresher than what we were at this stage last year," Harris said.

"We had a good win last weekend and we're definitely a lot better prepared than we were two weeks ago."

Last year Ag College were on a six-game winning streak leading into finals but couldn't find a way past Waratahs.

They did it while trying to come to terms with the death of teammate Andy Stanham during the season.

Now they've been able to focus on more on playing rugby.

"Last year was a completely different circumstance," Harris said.

"We were coming in on a wave of emotion with a long winning run.

"We probably got to the stage where we were worn out by the time we got to the grand final.

"Now we are a lot better prepared, we're a year older and it will hold us in good stead."

The odds are still stacked against Aggies.

Not only have they struggled to beat their more experienced rivals over the past five years, but Waratahs have only dropped two games in the last two seasons.

The last was a 53-26 loss to Griffith in round 12 but Harris isn't concerned about the past.

"We don't really care much about what has happened before - it just all comes down to Saturday," he said.

"Grand finals is where is matter and we are looking to leave our legacy with the club."

Harris is looking for a big defensive effort.

Waratahs found plenty of inroads a fortnight ago and it's the main thing Ag College are out to improve.

"Defence will win us the grand final," Harris said.

"If our defence holds up and we can do it for 80 minutes we'll come away with it.

"We've worked hard in the last two weeks to correct those issues and as much as anything it is a mental thing with our young team.

"We have to be mentally focused."

Ag College take a very similar side into this grand final as they did last year.

However with some impending graduations and long-term placements on the horizon the 23-year-old believes it's the right time to strike.

"The core of our team is coming towards the end of their uni degrees," Harris said.

"It is now or never to bring home some silverware for the club and leave our own legacy."
