Vikasati does the whole thing outdoors. No walls, no roof over the pools, just Southport sky from six in the morning until the stars come out. The contrast therapy is the draw. A 37-degree magnesium pool, a 14-degree cold one, ice baths at five, and what they claim is the Gold Coast's largest traditional sauna. You move between hot and cold and let the temperature do the work. It is elemental and a little bracing and, at forty-nine dollars for ninety minutes, refreshingly unprecious about it. Wear your swimmers. Watch the light change over the ninety minutes. Nature is part of the process here, not the backdrop.
