Of course not - they were stuck outside of Australia during a global pandemic and were unable to return home due to airlines limiting flights and cruiseships being floating cesspools of cross infection.
There was also a very vocal minority that strongly objected to restrictions on social gatherings and to various lockdowns when infection appeared that occurred in some of the Australian cities.
The vast majority of Australians (I'm one) were mostly pretty hapy with how the situation was handled in Australia with a few exceptions, the Federal Government failing to secure an early volume of vaccines being one of those failiings.
Yes, you can go online and find some very vocal Australians complaining very loudly about how it was a total shitshow that trampled their rights, referring to quarantine sites as internment camps, etc.
You can also compare that to vastly larger majority than understood the issues, the dangers, and supported the balance struck and measures taken.
There is no universe in which a spread of opinion did not exist.
Australia had early COVID cases, thanks to fairly uniform measures these were contained and overall the country had a very low death rate by global standards and maintained a strong economy during the pandemic.
