Well the Spanish flu changed it.At that time only the Commonwealth could insist on interstate Quarantine.The States as now insisted they had the right to manage their own affairs.The 2 most quarrelsome States were QLD and WA.
QLD didn't want troops landing in QLD and WA "seized" interstate trains.

After that once again States had to cede Quarantine powers to the Commonwealth and the Commonwealth Det. Of Health was set up.
But when Covid struck the States amended their own Health Acts and took back control.Here is QLD.
So the States took control.Bit rich to now try and blame the Commonwealth.
