Jenny Fitzgibbon 2011 (Add to this as you wish!)
Tune – this train is bound for glory, this train. The first verse can be used as a chorus.
Also see “Water for Life on this land” which is the same song for a different event, but might suit your purpose better.

The water – belongs to the nation on this land
The water – belongs to the nation on this land
The water – belongs to the nation
For feeding each future generation on this land
Lock the Gate on this Land

They’ll see – that we’re not teasin’ on this land x3
We’re out to protect the Great Artesian on this land
Lock the Gate on this Land

There’ll be a revolution on this land x 3
If the price of gas includes pollution on this land
Lock the Gate on this Land

There’ll be no fracking or drilling on this land x3
Cos we don’t want no poison spilling on this land
Lock the Gate on this Land

Profits to be made by the million on this land x3
Leaving a clean-up bill of a billion on this land
Lock the Gate to this Land
