While there they joined in a series of training and team-building exercises at Cricket Victoria High Performance Centre, and also toured the Melbourne Cricket Ground and the National Sports Museum.
"It was pretty cool. It was the first time we've done that. We had access to training and playing facilities and it really set the bar," the coach said.
Law, who is in his first season as player-coach, said they had named a 13-man travelling squad to offset any possible injuries.
"It just covers all bases," he said.
At 31, he is the oldest in a team that has a mixture of youth and experience, with five players in their debut season.
Zac Benton, Law and Keegan MacLachlan were all newcomers this year, while captain Andre Halbert and Carter Andrews were past representatives who had returned to the team this season.
They would look to proven top-order batman Matt Good for a good showing today although Law said he expected newcomer Bailey Te Tomo to make a mark.
"He's rated highly and I'm excited about his future," he said.
"I've faith in the guys that we can cause an upset."
