"It's an indicator of his consistency," says Kiwis coach Stephen Kearney. "He has gone to a new level."
"I'm not carried away but everything went well this season," adds Bromwich. I'm feeling very confident."
Bromwich took on more of a leadership role within the team before this year's Anzac test, after a slew of high profile withdrawals.
"I like to lead with my actions more than my words," says Bromwich, "But it is something I am becoming more comfortable with."
No one is more important to the Kiwis' cause than Bromwich on Saturday night. While the focus tends to fall on the likes of Shaun Johnson, Kieran Foran and Jason Taumalolo, tests are won in the trenches. Bromwich has the ability to dominate in that area, especially as Australia are without many of their regular starters.
The 25-year-old was part of an impressive effort in May's Anzac test, when the Kiwis surprised the more fancied Australians with a spirited, albeit patchy effort.
"We played really well for the first 60 minutes and then they blew us off the park in the last 20," says Bromwich. "We need to look at the first 40 and go from there. We believe in ourselves and we really need to take that belief into the game and see what happens."
