The try Kearn's scored against the New Zealanders was a turning point for Australian Rugby and he should always be remembered for that.
In what way?
It certainly wasn't a long term turning point because the Wallabies played as poorly after that, from time to time, as they had before it, from time to time.
Yet again the figures sugest that this is wishful thinking, hero worship, selective memory or all 3.
In the 10 years after the "finger" Australia beat NZ 38.35% of the time; In the 10 years before it 38.63%.
In terms of a contribution to the welfare of Australian rugby its impact was about the same as a huge centre field hit: it got the peanut gallery going but it had no other affect. And it certainly was not the end of Sean Fitzpatrick or the All Blacks.
There are 2 candidates based on results for the title of the "modern turning point in Australian rugby": one is 17 June 1978: up to that time australia's winning percentage against all comers was 33.17% - since that day our record has been 64.64% against all comers.
An alternative date would be 28 July 1979: prior to that date the winning rate was 33.17%. Since it 65.23%.
The second is a more savoury candidate. For the 10 years following this date Australia won 60.76% against all comers whereas in the 10 years before their winning ratio was 38.63%. Against NZ for the same periods it was 16% before and 36.11% after.
22% v -0.28%.
Turning point versus statistical irrelevance.
The work done by Amateurs in the late 70s and early to mid 80's in this country paved the way for the change in australia's fortunes. Kearns too was an amateur but to credit him with changing the course of the history of Australian rugby is to do a grave disservice to those who came before him and made it so that no Aussie team would fear anyone, including those from across the ditch.
