Sometime in an alternate 2005, a handwavium science event creates a situation where excessive rainfall occurs throughout much of Australia. This event, now referred to as "the great rainfall", was the start of the much greater event now called "the great greening", in which the greater rainfall and other variables (thanks to handwavium) creates a perfect environment to plants to grow.
Scientists of the world determined that this change of circumstances would be permanent, and if the Outback were left alone, much of it would turn into a rainforest in a few decades.
This turn of events creates a "land frenzy" in which many people from around Australia and the world rush to claim the newly available (and unoccupied) land in the Outback.
now for my question : how should australian government do in this event, especially in regard of the "land frenzy" ?
