(plural: ‘cockatoos‘; pronunciation: both the ‘C’s’ in this word are said with a ‘k’ sound as in “king”)
(in Australian English usage) the owner of a small farm or a settler in Australia and New Zealand;
a person who is given the job of looking out for anyone (any intruders) when the others of the gang do some illegal activities, such as gambling, drinking, etc.
Most wheat growing cockatoos in Australia are asking the government for more subsidies as wheat growing has become more and more expensive.
As Benson did not drink, he was asked to act as a cockatoo while the rest of us had beer and wine.
