And that is just as well because I believe the tone for the occasion will be set by the start of the two innings. On the one hand it will be McCullum against Mitchell Starc and Josh Hazlewood, and on the other it will be David Warner and Aaron Finch against Trent Boult and Tim Southee.
Whichever team comes through those particular arm-wrestles will be ahead in the match, perhaps never to be caught, and so there will be high-octane action right from ball one, something we have come to expect at this World Cup.
The good thing from a New Zealand perspective is that the MCG's big boundaries will provide plenty of scope for Daniel Vettori to show his full range of skills, and his ability with the ball means that, in one area at least, the Black Caps are clearly ahead of their rivals.
This is not the first major final New Zealand have reached, of course. We actually won the ICC Champions Trophy in Kenya in 2000 when I was captain - it was known as the ICC Knock-Out back then - and in 2009 the side finished as runners-up to Ricky Ponting's Australia when that event was held in South Africa.
But with due respect to those achievements, this is something on an entirely different scale.
You could compare it to the Rugby World Cup, a prize that eluded New Zealand for more than two decades before it was secured on home soil in 2011, but the feeling within the country seems completely different from four years ago.
Back then, there was little else except nervousness because there was a huge degree of expectation on the All Blacks.
By contrast, the successes of the cricket team in 2015 has brought with it a feeling of near-euphoria and excitement among the public at large.
The catchphrase of a major advertising campaign around the tournament has been "Dream Big" and that is exactly what the country and the team are doing right now.
Down the years, New Zealand have always been an unfashionable side but I do not think it will enter the minds of the players to see victory on Sunday as a way of scoring points or proof they deserve a higher profile among the elite teams.
Instead I think they will be focusing on enjoying themselves in the knowledge they are part of something that will, most likely, be the best experience of their professional lives.
And with Australia having home advantage and the backing of the majority of the 90-odd thousand fans at the venue they can go out and play with the freedom that has been the hallmark of their success in this tournament.
Win or lose, New Zealand's players have done their country proud but they will want to make sure they leave nothing in the dressing room because the chance to play in a World Cup final is as special as it gets.
And if, come Sunday night, Brendon McCullum is lifting that trophy above his head, it will get a whole lot more special for every one of them.
