"I'm really happy to win the round and extend my lead in the series," Lamont said, who qualified only 10th, satisfied to complete just a couple of laps of qualifying to secure a reasonable spot with the minimum of fuss.
But he turned it on for the racing proper, leading the first two races virtually from start to finish before settling for a solid third in the last race to secure the overall result.
"I put in the hard yards in the first two races and was happy to accept third in the last one ... job done. There is no point trying too hard to win all three races and risk crashing.
"I really need to thank everybody who has helped me, the CMR Red Bull KTM team, Jeff Leisk of KTM in Australia, Cannon Smith and Patrick Stafford of KTM in New Zealand, trainer John Appel, Dragon Goggles, Shift apparel and BikesportNZ.com for all their support. The track was a bit of a bog hole in places but the club did a really good job of the track considering the conditions and it was definitely a good weekend for me."
The Australian motocross championship series will continue at Appin, near Sydney, in New South Wales on Sunday, July 29.
Meanwhile, all terrain vehicle ace Ian Ffitch left his best until last on his way to successfully defending his New Zealand TT Championships title at Kuratau, near Taupo, at the weekend.
Trailing fellow Honda rider Camo Keegan, of Stratford, in the points standings as he lined his Honda TRX450R for the fifth and final race, Amberley's Ffitch knew he'd have to "pull one out of the bag" to reclaim the open class TT title he won for the first time last season.
That's exactly what he did, storming to victory and wrapping up the trophy for another year.
Despite his "favourite" tag, Ffitch was pushed all the way at the two-day event at the southern tip of Lake Taupo.
However, a cool head under pressure gave the vastly experienced 42-year-old the advantage where it counted.
He eventually took the title ahead of Rotorua's Jason Jepson and an unlucky Keegan.
The Taranaki rider unfortunately failed to score points in the last race because of a blocked fuel hose and slipped to third overall in the championship.
