The government on " health advice " had regions and in truth the areas outside of Greater Melbourne in Victoria were harshly treated as numbers were very low with the vast majority of shires having no covid at all.
When daily numbers hit 700 ( all a result of hotel quarantine bungling as a result of poor public policy implementation ) the justification was that people moving from Melbourne to places like Torquay which many do during holidays and on weekends would spread the virus so a police ring was placed around greater Melbourne preventing people from travelling to any other place unless it was strictly for work purposes and even then they needed a permit signed by the employer so effectively only essential goods and services to ports and supermarkets and warehouses were allowed.
We had 800 odd deaths in a national total of 909 to date.
Its not rocket science had we kept the virus outside nursing homes the death toll would have been much much lower.
We closed all passenger travel to and from all countries for many months and you still cannot leave the country outside for work or relocation.
All arrivals of returned citizens are placed in quarantine for at least 14 days but despite this various strains continue to creep into the public however since the second major lockdown in Victoria in numbers that allow contract tracing both primary and secondary to be managed reasonably effectively.
We are far more forgiving and complicit with Government Advice and Government bungling and interference into ones privacy and civil liberties.
Mini state border and hot spot lockdowns are triggered with single digit cases in fact often just one case recently bar NSW which has a right of centre government in place ( in the main ) and manages their numbers despite doing most of the heavy lifting for returned travellers and shutting down business as soon a new case in the community occurs.
