An alternative derivation is from Christopher Chippindale, who states that Khazi derives from Army slang used by expatriate officers of the British Empire who took a dislike to the habits of, and steaming rain forest inhabited by, the Khasi people of the Khasia hills on the northern frontier of India.
• Dunny
The Dunny is an Australian expression for an outside toilet or outhouse. The person who appeared weekly to empty the pan beneath the seat was known as the dunnyman. The word derives from the British dialect word dunnekin, meaning dung-house.
It is now an informal word used for any lavatory and is most often used referring to drop or pit lavatories in the Australian bush, which are also called thunderboxes.
