They later competed in the heats for the World Champs and progressed to the B Final, coming third.
Following was the first round of the Oceania competition, with the Ramsays placing eighth -- held back by problems with their bike's clutch.
"It's pretty rapid racing, so you don't have time to change your clutch between races," Derek said.
The pair fared better at the second round, held at Undera in Victoria, winning several heats, and again making the B Final (the only Kiwis to do so), and placing third.
"Both Ramsays agree their first overseas outing was a "big learning curve".
They were racing in tough conditions, coping with 35C temperatures, and scuffed dirt hampering their vision.
"When you're going that fast, the dirt sprays at you like water from a fire hose," Derek said.
Plus, the competition was stiff -- particularly the Australians with their "gruntier" bikes and aggressive tactics. Derek said, in one of the races, one of the teams had them pinned up against the side barrier with their bike, forcing them to make a quick recovery.
"Those guys can play dirty. They want to win at all costs, and they have no problems nudging you out of the way."
However, they were thrilled to meet World Champion Darrin Treloar -- who they almost caught up to during a heat.
"I think he was pretty impressed we nearly passed him," Matthew said. "We were over the moon."
The Ramsays are taking a break now racing season has finished, but will begin training intensively later in the year.
"We're going back for a spot on that podium," Derek said.
