Original lyrics from 1879. From Wikipedia:
“Should foreign foe e’er sight our coast,
Or dare a foot to land,
We’ll rouse to arms like sires of yore,
To guard our native strand;
Britannia then shall surely know,
Though oceans roll between,
Her sons in fair Australia’s land
Still keep their courage green.
In joyful strains then let us sing
Advance Australia fair.”
“For its adoption as the national anthem, the song was cut from four verses to two.”
