UK)", with Wikipedia adding, according to Tom Parry in 'Thumbs Up Australia: Hitchhiking the Outback' (2006), "the term is said to have been derived from the nickname given to men who carried fleeces in shearing sheds, after the sound they made as they ran around. It was also the name of a sawmill near the town of Wilga in South West of Western Australia that was abandoned in 1984", and further, according to 'The Dinkum Dictionary' (2010) by Susan Butler, Wikipedia states that "the term was being used in the early 1900s to describe a mythical outback town", which is what "Woop Woop" is in this movie.
