Here's another explanation to add to the list.
Victoria’s systemic problems behind second wave (paywalled)

A shortage of public health professionals in the Victorian bureaucracy is being blamed for the second wave of COVID-19 cases sweeping Melbourne, with a lack of contact tracers and an inability to train them at scale leaving the state more vulnerable than if the transmissions had occurred in NSW.
As the number of active infections in the state from an unknown source reached 456 on Wednesday, those central to the national pandemic response said there was a “systemic” problem within Victoria’s Department of Health and Human Services.
“The question is why has it happened in Melbourne and not Sydney? There is an underlying issue with the capability of the Victorian health system — it is not up to it,” one national COVID source said.
Another official said the number of Victorian public health professionals had already been “depleted” before the coronavirus outbreak, leaving the state less able to quickly train additional staff compared with the NSW Public Health Network.
“If you don’t have the core workforce of a size proportionate to your jurisdiction to train those people, that’s where it can come a little bit unstuck,” the official said. “There is a difference between the numbers of core public health people in Victoria compared to NSW.”
Victoria Police and the Australian Defence Force closed metropolitan Melbourne at midnight on Wednesday — and the Mitcham Shire — from the rest of the state as Premier Daniel Andrews struggles to bring an accelerating outbreak under control. Victoria recorded 134 new COVID-19 cases on Wednesday, with only 11 connected to other known infections.
Mr Andrews has acknowledged the strain in tracking the virus was critical to imposing a second stay at home order in Melbourne to control the spread. “You get to a point … where you just can’t find enough people to manage a group that’s doubling and doubling again,” he said.
“That’s not just the positive cases, but all their friends, all their family, everybody they’ve spent time with. It gets to a point where you can’t have confidence that you’re actually finding everybody … and pulling it up,” he said. “We can kid ourselves that we can do a thousand cases a day. We can’t do a thousand cases a day.’’
The Victoria-NSW border was sealed on Wednesday morning, with NSW Premier Gladys Berejiklian describing the likelihood of the contagion spreading north as “extremely high”.
The Berejiklian government is on Thursday expected to tighten restrictions in anticipation of further infections and after almost 50 passengers were allowed to disembark a Jetstar flight from Melbourne on Tuesday night without being screened for the virus.
Three passengers including one who refused to be screened have been referred to NSW Police.
Separately, a teenager holidaying on the NSW south coast was diagnosed with COVID-19 on Wednesday after a testing error by Victorian authorities. As Victoria grapples with the crisis, other states have sent staff to assist with contact tracing, including 70 “disease detectives” from NSW.
Melbourne University epidemiologist Tony Blakely described Victoria’s predicament as a combination of bad luck and poor management.
“The public health workforce started from a lower base in Victoria than in NSW,” he said.
“You have fewer people to take the calls coming in, to organise contact tracing, to oversee — and I’m speculating — the set up of quarantine. That can happen when your workforce is spread thin and you don’t have established expertise.”
The comments were echoed by Lindsay Grayson, an infectious diseases expert at Austin Health, has also criticised the Victorian Treasury for seeing DHHS as “nothing but a burden”.
“Like a choke hold that only gets released when there is barely a breath left – just enough to funding is provided to survive but never to thrive,” Professor Grayson wrote in The Age on Wednesday. “The Victorian Health Department is one of the worst-funded and dysfunctionally organised in the nation.”
A spokeswoman for NSW Health Minister Brad Hazzard said public health officials sent to Victoria to assist with contact tracing had interviewed more than 200 COVID-19 positive patients over the past five days.
A further 800 close contacts of those cases will be interviewed by the end of the week.
Victorian public health officials were tracing 5000 contacts earlier this week, a figure which was already nearing capacity before the most recent cases were detected.
For every active case, the known contacts increase in by between seven and nine.
There is no published data on the public health workforce numbers across the states, but one of the two officials who spoke to The Australian described the Victorian experience as one that would be “subject to strain in a pandemic”.
While health experts acknowledged that poor luck had played some role in the Victorian experience, they were quick to point out the state was less prepared to deal with this misfortune.
While NSW had been rocked by the Ruby Princess debacle, the inherent strength of the health department had meant the initial mistake was not compounded.
Another key contributor identified was the mismanagement of hotel quarantine arrangements, which has sparked a judicial inquiry into potential protocol breakdowns caused by hotel operators, private contractors and government agencies. Security guards monitoring were responsible for a number of localised outbreaks.
Large family gatherings were also believed to have been responsible for outbreaks, which, when combined with those caused by the security operators, have led to large pockets of transmission.
But epidemiologists warn that a fast and comprehensive contact tracing regimen is the only chance to effectively contain the virus.
“Unfortunately, because we don’t have a widespread available treatment including a vaccine, the only path forward is physical distancing and case detection,” Australian National University infectious diseases physician Sanjaya Senanayake said.
“It’s still important that 100 per cent of contacts are found in a short period of time, otherwise undetected contacts will have contracted the infection and you’ll never stop the outbreak,” Dr Senanayake told The Australian.
Curtin University infectious disease epidemiologist Archie Clements said Mr Andrew’s concerns over the state’s contact tracing capacity were justified. “I‘d be concerned if our outbreak numbers got ahead of contact tracing capacity, because that’s the point when you lose control.
“Until now we’ve been in control. In fact, the ability to do good contact tracing and to effectively isolate cases has been the key to Australia’s success in containing the virus in comparison to other countries. But if that capacity is exceeded and we do lose control, you just can’t get back on top of things.’’
Professor Clements warned that while geographical lockdowns were important in containment, without comprehensive contact tracing, “you are left with not knowing where the virus actually is”. “We don’t want to lose our privileged position where we basically know where all our cases are,” he said.
Both Dr Senanayake and Professor Clements said Mr Andrews needed to throw more resources at tracing the infections. “Basic contact tracing doesn’t require a high degree of skill, so long as there are good people supervising and co-ordinating,” Dr Senanayake said.
