That of best team in the state.

Having moved through the preliminary rounds, the boys will do battle with St George's Banksia in Sunday's Football NSW Champion of Champions final.

With the side falling short in last year's decider, coach Mark Tyssen said they are determined to triumph this time around.

"Last season Lake Heights fell just short with a narrow loss to Arncliffe," Tyssen said.

"This season the team wants to go all the way. After an undefeated regular season and winning the premiership and the grand final the team is now gunning for the trifecta."

The side progressed to the final with a 3-0 semi-final victory over Castle Hill United, with Lake Heights largely controlling proceedings.

Youngster Ruben Mayer put his team in a commanding position with the opening two goals of the match, before Bond Stergess added the Lions third to secure their place in Sunday's final.
