After going through the home and away season undefeated their confidence should be sky high, but assistant coach Brent Flood said the premiership is still up for grabs.

"It is great to get through unscathed in the regular season," Flood said.

"Finals is a different ball game. Everyone starts again."

Like most teams in the Maryborough Castlemaine District Football League, this week will be their toughest round of football to date.

Navarre meet the red hot Natte Bealiba, who in recent weeks, have been in the best form of the competition.

"It is a massive game, there is no doubt about it," Flood said.

"We want to set ourselves up for the rest of the finals and that means we need to start with a win."

Navarre is a young team, but given they won the premiership last year, they know what to expect on the big stage.

"We are under no illusion that we are guaranteed another chance," Flood said.

"You have to work for your finals spot from week to week. Position on the ladder means nothing, now it's a new season."

Navarre boasts one of the strongest forward lines in the competition, with league leading goalkicker Ash Driscoll at full forward.

Their backline is also tough at full strength, however Bryce Tickner is expected to have another week on the sidelines before he returns.

Navarre midfielders have had some work put into them at training over the last month to improve their clearance work and that will need to be on display with the strength of Natte Bealiba through the middle.

Brent Mortlock is a hard in and under player who will win the contested ball, while Stephen Ross is an outside runner who is very clean with his disposal.

Navarre will nullify their impact as much as possible, but their strategy for winning is simple.

"If each Navarre player beats his opponent, we win," Flood said.

Flood is expecting a big effort from everyone tomorrow and hopes all can bring something to the table.

"Whoever is picked has earned their spot," Flood said.

"For those who miss ,they have a run in the reserves and prove themselves. Players will need to stand up to hold their position."

Navarre has the bonus of having both junior teams and reserves also in the finals.

"It is every step together at the moment and we hope to keep it that way."

Navarre will take on Natte Bealiba tomorrow at Princes Park from 2.35pm.
