"We have a really competitive atmosphere building between the teams, with a lot of pride on the line for both high schools - including some really healthy banter.
"Both sides have new captains and vice-captains for the season, with all four players being former pupils of their respective high schools - some recent and some not so recent. JPC old boys will be captained by Manny Kumar with vice captain Liam Kelly. WHHS will be led by Joe O'Donoghue, and vice-captain Chris Nairn," Vanner said.
He said given Geyser City were working with a new long-term strategy, their aspirations for this season were "pretty simple".
"We want to build on the support we have received from the high schools and our members, and get our new brand and culture under way. We want to build depth in our player base and ensure we get two strong sides on the field every week and then all going well our season goal is to have both teams finish in the top four spots of this year's competition.
"Each squad has been put together with a great mix of batting and bowling skills, and on paper they look very even.
"From what we have seen at training the guys are already in good form with a couple of bowling standouts in Matt Mitchell, fresh from a good rugby season, returning to take one of the lead bowling roles for WHHS, and a new recruit for JPC with Satpal Singh coming from playing the last four seasons in Auckland.
"The other noticeable element from our trainings so far has been the vibe of the guys. There has been a real buzz around our new plans and some great banter between the squads, which we are really looking to build on.
"There's nothing like some friendly rivalry to add to the atmosphere of a cricket game, and even though we are one club we can already see a good amount of competition building between the teams. There will be no love lost on Saturday I am sure."
