The Australian Sweat Bathing association advocates for sauna culture in Australia.

Sauna practice in Australia
New South Wales
Best public sauna in Sydney: North Sydney Olympic pool at Milson’s point. Hot, great view, cheap. But no relaxing area, and you have to wear your swimmers. However, it is closed 😭 until 2023.
Bondi Icebergs is a similar situation but an even better view and a much worse sauna design.
Pricier, but naked-friendly for private rental, Nature’s Energy Newtown
Elsewhere sauna is cute.
