I haven't watched a single ball of this match, so all that I'm going off is the scorecard and Australia have totally outclassed NZ in batting and have made the Kiwi bowling look mediocre and not international standard.
No I wasn't around much near the time of the WC on PP, however I understand that NZ are trying to bat a similar manner to the way Australia batted vs their own bowlers - the only problem is that Starc, Johnson and Hazelwood are in a different league at home than their NZ counterparts and hence simply going after them isn't possible, you need to bat properly.
I don't see NZ batting out 180 overs although Macculum has scored a triple century before, it was against the mediocrity of India and not this Australian bowling.
Those are fair interpretations, but with respect, they are actually wrong.
What the Australians have very smartly done is turn this match into a Test version of the 2015 World Cup: grassless track making the slip cordon redundant, amassing a huge score fast, then making scoreboard pressure tell to get the opposition to lose wickets.
You are totally right that Australia have been able to punish a fast-medium attack, but that is largely down to the pitch-to-order, which offers zero seam movement off the pitch (although the modern version of the Kookaburra ball has no seam anyway).
If these teams were playing with a Dukes ball or on a sporting pitch the Aussies could not just plant their front foot half-forward and then drive away from their bodies. But on this pitch with this ball against this attack they can do it with total impunity.
It's the Kiwis fault for not assessing that their key bowler for the Gabba and the WACA was going to be Adam Milne.
And McCullum's fault in particular for giving Trent Boult far too much bowling at Lords and Headingley which stressed his back and left him on the comeback trail now, down on pace and fitness.
Funnily enough, the other half of your assessment it completely wrong. The Kiwis haven't tried to over-attack with the bat. They just had to bat on Day 2 after the wicket sped up and then lost wickets in a heap in the dark after tea on the second evening.
I think that as overall Test bowlers, Boult, Johnson and Starc are equals and Southee is not far behind.
But that is a global rating. On these modern grassless Aussie wickets you need to be 6 foot 4 or 140K to take wickets.
That's why Tremlett worked at 140K in 2010-11 and was toothless at 125K in 2013-14.
