So from what I can tell by reading the news the whole hotel quarantine fiasco happened because the government hiring prioritised racial diversity over actual qualifications, so the unqualified guards did things like let people out to get coffee and give people food they were allergic to, turning things into a Fawlty Towers darkfic. Then a toddler infected with the virus went delusional from it and painted the walls with their shit, after which they were sent outside so the staff could clean up their mess, during which they infected several people leading to the second wave responsible for 90% of Australia’s cases and fatalities, and probably about 50% in a country located entirely in the Southern Hemisphere (Brazil crosses the Equator), at least, that’s my interpretation.
