@Rock57; we visited South America in 1999 and knew only too well that we had to have vaccinations against yellow fever.
Upon our return a custom's beagle dog sniffed my wife who bent down to pat it because of her love of beagles - our own died about year beforehand. She was very quickly told to stop and was immediately checked.
Even your previous post demonstrated that Border Force is involved at airports and at ports - the release of passengers unchecked for COVID-19 into Sydney and without the specified 14 days in quarantine is a debacle that no-one involved can hide from - including Border Force who apparently just stood by and let it all happen.
It's the responsibility of politicians to establish structures such as Border Force and the NSW Health Dept - when they collectively stuff up because of confusion re rules and roles or under-resourcing, responsibility rests with those same politicians.
