Think you are going off track a little here.
My recent comments were about those NSW residents isolating at home since the second wave from Vic came to NSW (crossroads hotel onwards), not the hotel quarantine program or the failures before the hotel quarantine program for international arrivals came into being, nor those who had a pass to drive through/transit stopping outside of their permit.
Most of the articles you posted were from March, and the precise reason hotel isolation for international arrivals was introduced nationally. I think everyone can concede the international arrivals hotel quarantine program was sorely needed.
The case of the druggie Victorian resident who had been granted a transit permit in July to travel directly to Queensland via NSW, who did not, says nothing re NSW residents likelihood to comply with self isolation orders, These breaches from Victorians permitted to transit the state is one reason Gladys is now not allowing ACT residents to transit to return to ACT - everyone flies via SYD if coming from Vic except freight or border residents.
I had understood Vic weren't checking up on those positive local cases who were meant to be quarantining at home until media leaked that they had been going to work. Your link would say there were some checks which is good, but the fact that it was reported that significant numbers weren't at home when they should be was a clear point of community transmission. Also seemed to be ramped up significantly by ADF personnel once Vic lost control of the outbreak. I will never understand why people breach staying at home orders, weren't charged and put into policed quarantine Andrews et al were too lenient for too long.
NSW has had some hotel issues, never denied that, but have seen nothing like 20% of those meant to be isolating not being at home when checked. I can only recall 3 hotel escapes (the one you quoted above, plus the woman who set the fire alarms off and the one who conned her way out to the airport), which given NSW has taken over 60% of international arrivals since the program begun is quite small. Imperfect yes.
In interview last week Dr Chant said compliance checks had found people were isolating as expected - I cant find any articles since Crossroads outbreak of NSW residents not isolating when they should, which I take some comfort in.
