Portugal Colonial - Barrett try after the siren as New Zealand edge Australia 39-37

Coach Ian Foster's side came into the rare midweek Test at Melbourne after hammering Argentina 53-3 and clung on for back-to-back wins after Australia roared back from 31-13 down to take it to the wire.

They went to the break all square at 10-10 at a sold-out Docklands Stadium after a gruelling first half that saw a try apiece, three yellow cards and three All Blacks, including captain Sam Cane, limp off injured.

"What a classic," said relieved Cane. "To win on the buzzer we're hugely delighted."

Man-of-the-match Samisoni Taukei'aho, who scored two tries, added: "Dramatic is one word to describe it. It was quite nerve-racking. Full trust in the boys. They got it done."

A New Zealand try 90 seconds after the restart and a third yellow card for Australia appeared to end any hopes the home team had.

But two tries from Andrew Kellaway inside five minutes and another from Pete Samu set up an exciting finale.

Nic White nailed a penalty with three minutes left to put Australia in front, only for Bernard Foley, in his first game for three years, to be controversially penalised for time-wasting as he attempted to run down the clock.

It handed possession back to New Zealand and Barrett crossed after the final siren.

"Absolutely gutted. I don't know what to say," said Australia captain James Slipper.

"We wanted to put in performance tonight and we just fell short there. Probably the most cutting way to finish again, in my opinion."

The victory further eased pressure on Foster, and kept them top of the Rugby Championship with a game to play on 14 points, four above Australia.

The Springboks and Argentina face each other on Saturday. Both have nine points.

The win also ensured the Bledisloe Cup stayed in New Zealand's hands ahead of the final Rugby Championship Test at Eden Park next week.

After crushing Argentina in Hamilton, they were on a high, facing a new-look Wallabies with eight changes from the side that crashed 24-8 to South Africa.

And the home team was on the back foot immediately when Jed Holloway failed to collect the catch from the kickoff, which culminated in Taukei'aho flopping over in the corner after a powerful lineout drive.

Richie Mo'unga added the extras to give the visitors a dream 7-0 lead after four minutes, a welcome change after being slow out the blocks this year.

Mo'unga nailed a penalty to stretch the advantage before the Wallabies got on the board, courtesy of Foley slotting an easy three-pointer.

- Cruising -

In a blow for Australia, Kellaway had a try disallowed for failing to properly ground the ball, but they had momentum and Rob Valetini crashed over for a converted try to level the scores.

Making matters worse for New Zealand, Dalton Papali'i was yellow-carded, forcing the All Blacks into a frantic rearguard defence.

As he returned, Australia's Tom Wright and Darcy Swain were both sent to the sidelines for 10 minutes, penalised during the same period of play, to give New Zealand a two-man advantage.

They should have capitalised before the break, but Taukei'aho was denied a second try for not grounding properly.

There were no mistakes after the re-start, with Taukei'aho bursting through the defence after barely 90 seconds.

Ill-discipline cost Australia again with scrum-half Jake Gordon sin-binned. Mo'unga dotted down then Will Jordan flew to the line, both while he was off the park.

New Zealand looked to be cruising but two tries from Kellaway hauled Australia back to 27-31 and another from Samu, converted by Foley, made it 37-all with six minutes left.

White sensationally drilled a long-range penalty to put them in front before Barrett's late heroics.
