Now that Firaxis have shipped the "final" update/patch for Civ VI I have re-examined the start locations and concluded the Pangea map start params don't suit Australia. I've changed it to match that of Fractal map.
Great Barrier Reef is now a completely independent mod. It can be used on any map along with the Natural Wonder picker. But I will continue to package it together with Scrambled Australia as it was a feature request by civ fans.
