You took out the reference to a slang term for condoms in Australia. It was, in the '70s. It would be where the term came from for the dwellings. Dongas are small and uncomfortable, like a condom.
- All you have to do is provide evidence. Maybe a link to such a usage in an Australian book or newspaper. SemperBlotto 10:54, 17 September 2011 (UTC)
It could be a retrospectively applied acronym but I have heard that donga stands for demountable over night group accommodation. No reference unfortunately. —This unsigned comment was added by 220.127.116.11 (talk).
