Socceroos match-winner Brett Holman is confident the squad will shape up after they ship out for the World Cup, and learn from the mistakes made in their unconvincing friendly win over New Zealand.

Holman scored a last-gasp goal to give Australia what coach Pim Verbeek labelled an undeserved 2-1 victory over a brave All Whites side at the MCG on Monday night.

It worryingly exposed several areas of concern ahead of the World Cup, especially the Socceroos' inability to deal with New Zealand's bruising three-pronged strikeforce both in the air and on the ground.

After being totally outclassed in the first 45 minutes, Holman and four other substitutes provided some much-needed energy to the Socceroos' cause.

And Holman was rewarded with his clinical finish following a neat lofted pass from fellow sub Carl Valeri to seal the win.

The Dutch-based midfielder said the Socceroos now knew what they needed to work on, and believes the three weeks they will spend in South Africa preparing for their opening match against Germany on June 14 (Australian time) will allow them to iron out the kinks.

"It's the best time to pick those negatives out and work on them. And we've still got three weeks to work on those things and cut them out," Holman said.

"You always pick out the things that can get better, and have to get better. It definitely motivates you.

"We can definitely get better. We've got enough quality to do some special things and I'm sure we can."

For the much-maligned Holman, his second goal in 30 internationals helped silence the critics who blast his inefficiency in front of goal.

"It was a well-needed goal, both for me and for the team," Holman said.

"It was a slow start but in the second half we picked it up pretty reasonably. There's positives and negatives to take out of it."

Midfielder Dario Vidosic confirmed he had recovered well from a slight hamstring twinge he suffered late in the match, after netting his first goal for his country.

"It pulled up okay and I got a bit of acupuncture done this morning so I'll be fine," Vidosic said.

"It was good to score my first international goal, especially for it to be at the 'G in front of 55,000 people."
