Things turned fiery at several stages of the game, including a lengthy scuffle after the half-time siren as a run of three straight goals saw Lauderdale take a 10-point lead.

The Northern Bombers fought back, however, dominating the third term and kicking five on the trot before surviving a late fightback to win 10.17 (77) to 10.7 (67).

Next weekend's trip to Kingborough marks the Bombers' final road trip of the season leading into a last round clash with Glenorchy and yet another finals tilt.

"It was a really good game for us going into the back half of the year," North Launceston coach Taylor Whitford said.

"They're a solid unit Lauderdale in terms of how they play footy and the mentality they bring and we probably needed a game like that.

"That game is going to hold us in really good stead for what happens when we're on and what happens when we're not, so we can definitely take a massive learning out of today.

"We had a lot of spirit and heart to come back at half time down, get the game on our terms in the third and walk away with it in the end."

Fresh from a thumping win over Launceston, Lauderdale matched it with the Bombers early as both sides enjoyed free-flowing end-to-end passages.

Harry Richmond (three goals) continued his hot form while at the other end Jake Laskey and Bart McCulloch traded contested grabs.

Laskey capitalised on two uncharacteristic Lauderdale foot errors early in third term, delivering one lace out to McCulloch and snapping the second around his body.

Brad Cox-Goodyer joined the party with a trademark 50m running goal as the lead stretched out to 27 points but the visitors had one last trick up their sleeve.

Identical snaps from Jack Dance and Luke Nelson sparked some interest before Sam Siggins' sublime left-foot checkside trimmed the margin to 10 at the 20-minute mark.

But the Bombers held on in an even team performance.

"Alex [Lee] had a down week last week in terms of his expectations and our expectations of him and he responded really really well, I thought he was dominant through that ruck," Whitford said.

"Baynen Lowe for a 17-year-old kid played really well and Bart is in pretty good form - Foony [Jay Foon] and [Braden] van Buuren as well down back.

"[Bart and Jake] have only played a handful of games together so they're going to keep getting better at that and Tom Donnelly played an important role for us up the ground as a forward - he did it really well as that player we could use out of defence."

Earlier, Lauderdale lost three stars before the game with Adrian Kalcovski, Nathan Oakes and Tyler Martin all pulling out.

Southern Bombers assistant Clint Brown praised the efforts of co-captains Bryce Walsh and Josh McGuinness, who formed a formidable midfield partnership for the second week running.

"We probably lost our way again and let them play the style that they want to play - they like to get numbers behind the ball which I think they did well, especially in that third quarter which probably cost us the game in the end," Brown reflected.

"It was a bit of an arm-wrestle in the first half and then a bit of a hoo-ha at half time and they readjusted after that break and put us to the sword a little bit.

"In the third quarter we probably gave them some cheap goals - kicking straight to them in the backline, silly free kicks and a 50m penalty - it just hurts you against teams like that, they make you pay and in the end it's 10 points difference and those sort of goals that make the difference."
