Victoria should extend lockdown to entire state

The restrictions in place for metropolitan Melbourne now are in some ways stricter than those that were in force during New Zealand’s Covid-19 lockdown. A curfew is in place and most people have to wear masks when they leave their home — neither of which happened in New Zealand.

But the state of Victoria has lost valuable time to bring the outbreak under control. Stage 3 restrictions that came into force on July 8 for everyone living in metropolitan Melbourne and the Mitchell Shire provided too many opportunities for the virus to spread.

As a result, there are now around 7000 active cases, and still several hundred new cases each day. For more than 2000 cases, contact tracers don’t yet know where people were exposed to the virus.

My major concern with Victoria’s approach is that cases outside Melbourne will continue to grow under stage 3 restrictions. The sad reality is that the more opportunities the virus has to spread from person to person, the harder it will be to stop community transmission.

Putting the entire state under stage 4 restrictions would give Victoria the best chance of success, rather than setting it up to play an endless game of Covid-19 whack-a-mole.

There is a major difference in how Australia and New Zealand approached Covid-19 when it first emerged. New Zealand decided on an elimination strategy, while Australia took the suppression path. It meant Australia could be looser with its earlier restrictions and relax them more quickly.

In March, New Zealanders entered an Alert Level 4 lockdown, aimed at stopping community transmission

of the virus altogether. And it worked. In contrast, the goal of Australia’s suppression strategy was to lower community transmission to some manageable level.

Between early April and the middle of June, new case numbers

in the state of Victoria were between one and 20 each day, including

some cases of community transmission. But they began to

rise again from the end of June.

How asking people to stick to their ‘bubble’ could help

During New Zealand’s Alert Level 4, our households became "bubbles".

There were no funerals and we couldn’t get takeaways. Bakeries

and butchers were closed. Construction was shut down unless the work was needed to make a building safe. The bubble concept helped people to restrict their contact to those within a home or between households with shared care arrangements. It reinforced that any contact with people from another bubble would provide an opportunity for the virus to spread.

Even under Melbourne’s stage 4 lockdown rules, that message of choosing a bubble at the start of lockdown and trying hard to stick to it could be a helpful addition to Victoria’s health messaging.

While announcing the new business restrictions for Melbourne and regional Victoria on Tuesday, Victorian Premier Daniel Andrews was asked about how his lockdown rules compared with New Zealand — and he replied that "this is a uniquely Australian and Victorian approach", adding:

"If you look at what New Zealand did, they went a fair bit further than this."

And in many ways he’s right: while Melbourne has a curfew and compulsory mask wearing, it’s not closing as many non-essential businesses or restricting people’s movement for things such as takeaways as strictly as New Zealand did in Level 4 lockdown.

While Victoria and New Zealand have similar populations, no-one should pretend that one country’s strategy is the perfect solution for another. Victoria today is at a very different stage to New Zealand a few months ago.

New Zealand went into lockdown with just 102 confirmed cases and no known deaths. Compare that with about 7000 active cases for Victoria right now. That’s why I think it’s all the more important to make the stage 4 lockdown state-wide. Without it, Victoria runs a very high risk of having to do it all again in a few months’ time. —
