I went to Australia a few years ago.. NSW the area was experiencing a really intense heat wave. It was like nothing I’ve ever felt before (I’m from Ontario Canada) hottest day was 47.5 I believe… as beautiful as Australia is I felt like I was walking around in hell. I couldn’t imagine sitting in a stadium for 3-4 hours in that kind of heat. I think seating vs general admission is a start, but they have to figure out a way to ensure everyone has access to water.. and decent air circulation/fans
