OK, the subject of this song may not be commonly regarded as Aussie or Kiwi, or even Southern Hemisphere, BUT, I prefer to think that - just like the ubiquitous Chickenman - "He's EVERYWHERE, He's EVERYWHERE"!!
So, this is a session favourite from Qld's CLOUDSTREET.

THE GREEN MAN ~ John Thompson

Ch.        
The Green Man’s a traveller, a reveller, unraveller
Of dreams and of fancies from first to the last
Older than all men, living in all things
Son, father and sage, long live The Green Man.


First light of first morning saw The Green Man there waiting
He saw the creation and joined in the dance
All creatures grew round him
He grew with them singing
The first song of all, sing of The Green Man.

Quietly watching and waiting and learning
The storms are his fury, the lightning his laugh
The first leaf of spring is his beauty and glory
His stillness, his power, in the trees in his path.

There are fewer trees now, but The Man is not sleeping
‘Though our ruin brings sorrow to Time’s oldest heart
In our soul we may find him and remember his wisdom
And rekindle the flames, once again make a start.


There are a couple of Cloudstreet versions on YT - This is from "Swallow the Concertina" in 2000 (and the second is from 2010's "Circus of Desires") :
