As it happened: Victoria imposes stage four restrictions including curfew, 5km lockdown limit; NSW battles clusters, Australian death toll jumps to 208

So that wraps up a momentous day in this pandemic crisis. For Monday's coverage, click here.

Here's the biggest developments of the day:

• Victorian Premier Daniel Andrews has announced a state of disaster that will see a curfew imposed on Melbourne for six weeks meaning residents must remain at home between 8pm and 5am;
• As part of a suite of tough new restrictions Melburnians will not be allowed to travel more than 5km once a day to do their shopping (further if their nearest supermarket is more than 5km away). Only one person per household will be allowed to make the trip and only once a day;
• Regional Victoria will also be placed under stage three restrictions later this week;
• Mr Andrews said the new restrictions were needed because of a wave of nearly 800 so-called "mystery" infections where the origin was completely unknown;
• Students across Victoria will return to remote learning on Wednesday, with tighter exemptions for children of essential workers than the government imposed last lockdown;
• Prime Minister Scott Morrison has warned Australia's economic recovery from the coronavirus pandemic hinges on how quickly Victoria can overcome the latest outbreak;
• NSW Premier Gladys Berejiklian is urging face masks be worn on public transport and in supermarkets as the state reported another 12 new coronavirus cases on Sunday. She said NSW had entered a "very critical stage".

• Queensland's latest case of COVID-19 flew on a Jetstar flight from Sydney to the Sunshine Coast while infectious, sparking a public health alert for fellow passengers. The man returned from overseas and was allowed to then board the domestic flight because he is a consulate staffer.

We will be back tomorrow morning. For Monday's coverage, click here. Until then stay safe and look after one another.

NSW Health is directing anyone who visited two venues in the Hunter region to get tested for COVID-19 and self-isolate for 14 days after someone from Sydney with coronavirus visited the area while infectious.

The public health alert issued late on Sunday night states any person who attended Hotel Jesmond on Wednesday July 29 between 7.30pm and 9.30pm, or Wallsend Diggers on Thursday July 30 between 7.30pm and 9.30pm must go into self-quarantine for two weeks.

Hunter New England Health public health controller Dr David Durrheim said anyone in attendance during these times "may be at risk of infection".

The venues were closed to ensure a thorough cleaning process could be completed. Health officials are poring over the venues’ guest registers to trace and contact any people who were there during the two-hour windows.

In a Facebook post, state Labor MP Sonia Hornery praised the Wallsend Diggers for being able to “immediately identify all those who were on the premises” on Thursday night.

Even if the first test comes back negative, NSW Health says anyone developing symptoms should get re-tested. A drive-through clinic is available at the University of Newcastle from 8am to 4pm every day.

Quite a few readers are writing into us with scenarios and wondering if they meet the rules.

Here's one that caught my eye as the parent of some little ones and hopefully helps a bit.

Question - We are both working from home. We have two small children. Can one of us take both kids out while exercising, while the other parent is working, or can we only take one child at a time? We live in a flat so rely on leaving the house for any outside play. Our children are too little for conventional “exercise” to be of any use. Are they allowed to use the grass at the park (I know the playground equipment is closed) or parkland at the creek (within the 5k radius)? If yes - will we be fined if they are looking at bugs or pretending to be dogs etc rather than being physically active? What is allowable “exercise” for a three year old and where can we do it?

Answer - Well first thing I'd say is we're not entirely certain how the authorities are going to police the rules but here's some of what Premier Daniel Andrews had to say today which should hopefully answer that question. Particularly note the bit in bold: "You will be allowed to have one hour of exercise, no further than 5km from your home. That means it is fresh air. It is a jog. It is a walk. It is in your local neighbourhood. It is staying close to home or in your home and there will no longer be able to be any groups bigger than two, regardless of whether they are from your family or someone else. There will be commonsense exemptions for children who are being cared for and cannot be left at home, things of that nature."

My sense, based on that, is that small children running around on the grass for a little toddle at the local oval is not going to attract the ire of the police.

In Yarraville, Lee Smith-Moir has been delighting users of Cruickshank Park since creating her own version of the rainbow trail, with 20 flags to spot, in March.

From a fun facts educational trail to a Ministry of Silly Walks path, she has been setting up different activities to cheer up locals on their daily exercise.

“Every day, we get people saying it brightens their day … they say it gives them a laugh or 'I learnt something really interesting,' ” Ms Smith-Moir said.

“It’s become a little happy place at the edge of the park.”

The retiree even built a giant puzzle wall, filled with optical illusions and quizzes, on the side of her home that sits on the edge of the park.

Coles supermarkets, Liquorland, Vintage Cellars, First Choice and First Choice Liquor Market stores across Melbourne will not admit new customers from 7.30pm and close at 7.45pm in response to the Victorian government's new curfew for the city.

According to a statement from Coles, the new hours policy will not apply to stores that would otherwise close earlier nor to Coles Express outlets which would continue to trade so that essential services and exempt transport providers can get fuel and other essentials.

"In line with the curfew requirements, we ask that customers shop alone wherever possible and visit our stores no more than once per day," the company said.

Coles will also introduce new limited purchase limits for Victorian customers on chicken breasts, chicken thighs and mince.

Good evening, Mathew Dunckley here, taking over from Kate Rose.

If you're looking for a quick reckoner on some of the key new rules for those living in Melbourne's stage four lockdown here's a graphic we've put together which seeks to put them in one place.

Melbourne is, as of 8pm, under the first curfew it has experienced. We mentioned war historian Dr Michael McKernan earlier, who pointed out that even during the world wars Melbourne didn't have a curfew.

From now until 5am everybody is expected to be in their homes unless they are working or for caregiving or medical reasons, and it will be same for the next 41 nights.

As we adjust to the new way of living for these six weeks, it's worth noting the unprecedented times we live in, how unsettling it is for everybody - even those who may appear to be coping - and remember to support each other as much as we can through the times ahead.

We may not be able to see friends and family, or unwind with a quiet (late) evening walk, but there is still support available and it's important to reach out for help if you need it.

If you or anyone you know needs support, call Kids Helpline 1800 551 800, Lifeline 13 11 14, Mensline 1300 789 978 or Beyond Blue's coronavirus mental wellbeing support service on 1800 512 348.
