|Roadside tea break.|
Tea is made by boiling water in the tin can (billy), then adding tea leaves into the boiling water. The resulting brew can slightly smoky in flavour (depending upon circumstances) which need not be a bad thing, given the preponderance of cheap tea leaves in the bush, and the ..er... variation in mineral, sediment & other content of the water.
There is sufficient pictorial information in this photo to deduce where it is taken, for those who are familiar with Australia. You should be able to get within 10-15% of the continental land mass, possibly much less.
The references in the photo are cultural, economic, and of course natural.
The cultural references are heavily nuanced, very specific, and won't be grasped by more than a very small percentage of the population.
I'll update with more information in a week or so.
Update: Well that was much longer than a week! The clue is in the type of soil, the type of vegetation, the amount of money that has been spent on the highway (note the highway is gravel only) and the man in the photo is wearing a combination of shearer's moccassins with the clothes (especially hat) of a stockman from large scale open range cattle country.
