The abundance of water flowing across hundreds of miles and through dozens of streams has turned the rugged region into a spectacular explosion of life.
And much of that water is reaching Lake Eyre, normally a glistening salt flat on the edge of the Simpson Desert.
This has prompted thousands of birds to fly long journeys to breed in an Eden-like environment that can remain parched and barren for years at a time.
“These boom periods are when the whole biological system takes off, and whatever level you're looking at, from the microscopic up to the pelican, they're doing their thing,” leading wildlife expert Richard Kingsford told the Australian Broadcasting Corp.
