Went to the Warrnambool Hot Springs. These were very much a luxurious experience compared to the hot springs we did out in western Queensland. They have multiple pools aromatherapy, mood lighting and some with waterfalls. Each one is a different temperature and there is a very cold plunge pool. It was really good. I even managed the cold plunge pool twice.  Would definitely do this again.  They even had a machine to dry your swimwear!
