The deputy Controller of Customs states that prohibited aliens cannot enter Australia from the north because of hostile blacks, who hate and attack them.

They fights their fights and they hunt their game,
As they did before the white man came,
Far in the unexplored Outback,
Where still Australia's mostly black.

They little know of white men's laws,
Or of Australia's cherished cause,
Or any of that bag of tricks
Of policies or politics.

Yet, tho' they little dream of it,
Our wild black brothers do their bit;
For while they hanker for a fight
They help to keep Australia white.
