Possible Impact crater in Australia

If this crater (inner ring ~600 km, outer ring ~2000 km) proves out, this would make it the largest known impact event.  Chixilub is small potatoes compared to it.  Controversy surrounds the finding.
Publication in scientific literature is forthcoming, but not yet available.  This would have obvious implications for the end-Ediacaran mass extinction.
