The epicentre of Australia's coronavirus outbreak, Melbourne and Mitchell Shire, is coming up on three weeks into lockdown.
Residents must stay home except for essential shopping, care, exercise, study or work reasons, and on Thursday it became mandatory to wear a mask in public places.
Despite these actions, daily new case numbers have stayed stubbornly high and yesterday, reached a new record of 532.
So why hasn't Victoria's lockdown brought case numbers down more dramatically? And what else could we be doing to stop the spread?
We put those questions to the experts. Here's what they said.
Masks may be changing our behaviour
By now the case numbers were hoped to be dramatically lower, says Dr Philip Russo, president of the Australasian College of Infection Prevention and Control.
But the fact we only have a loose lid on infection doesn't come down to the Government's response; it's squarely on the public, Dr Russo says.
"Clearly people aren't following the guidelines and perhaps there's a sense that they're not going to be bothered too much if they do get the infection," Dr Russo says.
"There's some really obvious disobedience displayed on social media."
It's pleasing that mask-wearing has been largely embraced in Melbourne, but Dr Russo worries people will have a new false sense of confidence and leave their house more and more.
"Although we're all wearing masks now we still need to continue to only go out for the four reasons (to shop for food, for medical treatment, exercise or work and study).
Compliance appears to be a 'when it suits me' idea for some and the daily hype and hysteria online is distracting people from the key messages, Dr Russo says.
"It's still has to be about distancing, hygiene and staying at home."
Pressure to turn up to work
Victorian Premier Daniel Andrews says "far too many people" are going to work while sick, instead of getting tested and staying home while waiting for a result, labelling it "the biggest driver" of coronavirus transmission in the state.
The problem has been particularly prevalent in aged care, the Premier says.
Julie Leask, a social scientist who specialises in risk communication and nursing at the University of Sydney, says this reluctance to call in sick is largely linked to how financially stable people feel.
"For example, for casual workers ...isolation after a test could mean no work, less chance you will get a shift in future, and considerable financial stress. In that situation, it's easy to rationalise a scratchy throat as just being a bit of a cold," she says.
Professor Leask says casualisation and presenteeism — working while ill — was already a problem in the health industry so we couldn't expect it to be resolved overnight.
Weak lines of communication with culturally and linguistically diverse people could also be a setback, but Professor Leask stressed each state was in urgent need of behavioural data to fully understand people's attitudes.
"We need better evidence on where the vulnerabilities are occurring. Having data on the biggest barriers to needed behaviours will tell governments where they need to most improve processes."
More full-scale lockdowns were needed
Professor Mary-Louise McLaws, epidemiologist and World Health Organisation member, says there's one major reason case numbers keep spiralling upwards.
"It's simple, the ring-fencing wasn't done properly. If you lock down people you actually have to keep them there, you don't let them leave," she says.
Professor McLaws believes full-scale lockdowns, like those implemented in public housing, should have been applied in hotspots weeks ago so people weren't leaving for work .
"But if you're going to do the 'lite' version of ring-fencing you should at least mandate that people wear masks to work."
Aged care, distribution centres, meatworks, cool stores and warehouses have driven most of the second wave in Victoria, but Professor McLaws said this could have been avoided if authorities had learnt from mistakes elsewhere.
"We knew that aged care was an area of severe underemployment and many staff work across facilities. If we didn't learn that from Tasmania, we should have learnt that from NSW. But still those workers weren't required to wear masks in the early phase."
Professor McLaws says she understands there are a multitude of reasons why some workers feel pressured to attend work so the best approach is to change the work environment.
"If you can't put up perspex barriers then make sure all workers are wearing face shields... but really what should have been done is experts visiting factories and the like to assist employers."
Notwithstanding the mistakes made, Professor McLaws says Victorians should "hold their mettle" as not enough time has passed.
We haven't seen the full effect of masks yet
It's been less than a week since the introduction of mandate mask wearing, so the benefits of that aren't being seen in the daily case numbers yet, says Hassan Vally, an epidemiologist at LaTrobe University.
"We're only four days, five days since that happened. I've always had it in my head that come Wednesday, this week, we would probably see the drop associated with mask wearing," Dr Vally says.
"That's probably the easiest thing to explain. And then it gets really messy after that."
One thing that seems to go hand-in-hand with a rise in daily case numbers is a call for stage four restrictions, but Dr Vally says that's premature, and a blunt instrument.
"If it was that easy a decision, every single person would make that. We'd all give up four weeks of our life to stop this horribleness that we're in right now.
"But I don't think it's as easy as that and there's a huge cost associated with shutting everything down."
More effective, he says, is targeted shutdowns based on good evidence.
One of the issues is aged care, which can't simply be shut down, and authorities are working on improving infection control measures in that sector.
"There's an extraordinary amount of effort being done to limit the spread of cases through these workplaces and aged care centres."
Despite the complexity of the Melbourne outbreak, Dr Vally is hopeful the shift in the curve will be evident soon.
"I remain very optimistic that we will maybe have a few more days of hovering around this level and it might even go a little bit higher but then I really feel like towards the end of this week ... we'll start to see some positive results."
Bad luck
The numbers in Victoria may look bad, but they would have been many times worse without intervention, says Gideon Meyerowitz-Katz, an epidemiologist at the University of Wollongong.
Just how much worse is impossible to say, but outbreaks in other parts of the world with similar population densities to Melbourne have seen exponential increases with thousands of cases a day, Mr Meyorwitz-Katz says.
"I understand people's frustration that they're making these sacrifices [but] without these actions, if we had everyone still mingling like we were a few weeks ago, we would expect to see far more numbers than we have seen already."
He says the continued rise in cases is probably a sign that a lot of people were infected early on in the outbreak, and the after effects of that are still trickling through.
"Most likely, what we're seeing now is an artefact of the last few weeks and we would expect those cases to stay at this level for a while longer, I would guess, because these people were infected not today, not yesterday, but maybe even a week ago or more," he says.
"It's really a matter of patience."
As for why it's happened in Victoria? Bad luck, on the most part.
"Unless you have zero circulating cases, which fortunately some states in Australia have managed to maintain, there's always the potential, even if there's a very small risk, of having an outbreak. But it can happen.
