The bowlers all had a good workout, while there were centuries for three of the top six batsmen and only Kane Williamson really missed out with the bat, making just three and 14.
Australia A's attack included three fast-medium bowlers still to win a test cap and at least two of them will walk out on the Gabba this Thursday for the start of the two-test series.
James Pattinson was the most successful of the three, taking four for 96 in the first innings, while both left armer Mitchell Starc and Ben Cutting picked up wickets.
"I think we'll be in a great space to face them and do well against them," Guptill said.
"It was a chance to learn what they're about. I haven't really faced them before so it was good to get a bit of a sighter of them leading into the test.
"They've got some good stuff but if we can do what we did in the Australia A match we will be in great stead for the test."
Guptill got a double of 43 and 47 and is in a solid run of form, through three countries in the past few weeks.
In two T20 internationals in Zimbabwe Guptill scored 40 not out and 67; followed that with 74 and 105 in the two ODIs he played; scored 109 in the only test at Bulawayo; and made 195 not out and 27 for Auckland against Canterbury at Rangiora before heading to Brisbane.
New Zealand players have spoken about the importance of facing up to Australia and playing without trepidation. Given that New Zealand have won just two tests out of 26 on Australian soil, and those 26 years ago, there's much riding on the series, which ends at Hobart next week.
Young allrounder Doug Bracewell, who caught the eye against Australia A with a run-a-ball 73 not out and four wickets in their only innings, doesn't do trepidation and joined in the general up and at 'em theme.
"Before we came over we said we want to be more aggressive and ruthless, and having more mongrel as a team," he said.
Captain Ross Taylor helped himself to a century on Sunday, much of it in partnership with Jesse Ryder who clobbered a world record-equalling 16 sixes on his way to 175 off 137 balls.
"He batted well at the start and let loose at the end. To score 175 on any ground, regardless of where it is, you've got to be confident with that," Taylor said.
He and coach John Wright must decide whether to go into the test with the usual configuration or six batsmen, a wicketkeeper, spinner Dan Vettori and three fast-medium bowlers, or go for broke, use all four seamers and omit a batsman.
He played down Australia's perceived inexperience, pointing out that veteran batsmen, Ricky Ponting, Mike Hussey and captain Michael Clarke all average around 50 and "I'm sure the younger players will be looking up to them".
"We've got a pretty young team as well. We are probably going through a bit of a transitional stage too.
"But I guess it makes for a good contest and I'm sure the New Zealand public are looking forward to it, and the Australian public too."
