We were not sure whether your proposed sauna will be a free-standing cabin or whether you are lining a room inside a building. If it's a free-standing cabin a number of eucalypts could be used for the external cladding. You will find some Australian hardwood options on the net here: https://www.boral.com.au/products/timber/cladding/cladding. The internal linings will be exposed to wider fluctuations in temperature and moisture content, and need to be a highly dimensionally stable species. For this reason, in our experience most commercial sauna builders use western red cedar. However, you could discuss this with a local sauna builder who might have found a wider range of species to be suitable.Sauna
