I think the data speaks for itself. Millions of ETOPS hours flown with no defineable risk increase. Additionally ETOPS is dead and gone, it is now EDTO, where much more than just engine failure is considered, and in those areas 4 eng aircraft have zero safety advantage over a modern twin. Further if Australia was to go alone against the globally accepted ICAO EDTO standard, both Australian International airlines would become a footnote in the history books within a year as they became unable to compete against every other airline flying big twins.

That race has been run and won.

The assertion that CASA put cost ahead of safety is a totally different issue and one that I think is beyond doubt, but you will need to come up with a better argument than ETOPS/EDTO.
