Cameron Meyer placed second and Nathan Haas fourth in the demanding 183.6km race in Ballarat.
Meyer said the race was one of the toughest yet on the course.
“The heat today made it a war of attrition. I’m really happy with my silver medal.
“It is my first time on the podium for the road race and unfortunately the peloton gave Jack Bobridge too much of a gap to bring back. He was super strong and deserved the title.”
Meyer said he felt good throughout and that he enjoyed working with Haas and Mark Renshaw.
“For a three-man team to go and finish second and fourth is a great result and a fantastic start to our Australian summer races. I am now looking forward to the Tour Down Under.”
