Australia How the Bondi COVID-19 cluster compares to last year's outbreaks
Here's what we know about Sydney's latest COVID-19 cases
Watching a movie and grabbing a morning coffee has sparked Sydney's latest COVID-19 transmission scare. Here's what we know.A person who lives with the man also tested positive late on Wednesday evening, and further venues of concern were added to the list of places that both had visited while potentially infectious.
Sydney's Bondi COVID-19 outbreak is moving fast, but not as fast as other clusters the city has experienced during the pandemic.
The Bondi cluster stands at 31 cases as of 11:00am yesterday.
The ABC analysed the first eight days of three clusters: the current outbreak in Bondi, the Avalon cluster last Christmas, and the Crossroads Hotel cluster that sparked NSW's second wave last year.
It showed that the Avalon cluster took off at a faster rate than the Bondi outbreak, driven by a super-spreader event at the Avalon Beach RSL Club, and subsequent cases at the Avalon Bowling Club.

The highly transmissible Delta variant spreading from the Eastern Suburbs into other parts of Sydney has put the city on edge, as new positive cases comes to light having shared little more than a crossover with Patient Zero. As the number of cases grew on Friday to three people, so to has the list of exposure sites increased. The highly transmissible Delta variant has caused the exposure sites to spread from the Eastern Suburbs into other parts of Sydney, with new positive cases having shared little more than a fleeting crossover at the same store or cafe as Patient Zero, a limousine driver.
That cluster eventually reached 151 cases before it ended in January.
Yesterday was day eight of the Bondi cluster, on the same day the Avalon cluster had reached 119 cases, and the Crossroads Hotel cluster was at 50 cases.
Catherine Bennett, chair of epidemiology at Deakin University, said the Bondi outbreak was similar to the Crossroads outbreak, which started with "an initial landing" and very quick spread.
The Bondi outbreak is being driven by the Delta variant of COVID-19, which was first detected in India but has since spread throughout the world.
The strain is more infectious than other variants and has resulted in people being infected in Bondi after only fleeting contact with COVID cases.
Professor Bennett said the higher infectiousness of the Delta variant did not mean the outbreak was out of control, or was uncontrollable.

As contact tracers scramble to track venues visited by COVID-19 cases, the list of venues which at first was focused on the eastern suburbs, has now expanded to include Drummoyne, Castle Hill, Campbelltown and Merrylands in Western Sydney.
She said that unlike the recent outbreak in Melbourne, the Sydney outbreak was still at only the second generation of spread.
"That brings the real footprint of the case numbers back down to something more manageable in terms of the people they don't know about or might have been out and infectious," she said.
The Melbourne outbreak was at the fourth or fifth generation before the first cases were identified.
However, she said the worst case scenario for the current outbreak was "a bad luck situation".
"That is more likely to happen with this virus because it does give you a higher viral load and if that person is a good shedder of the virus and is also out and about. Put those three things together and it just means the spark is a bigger spark," she said.
NSW Premier Gladys Berejiklian announced a raft of new measures in Sydney to contain the outbreak, including restricting the movement of people in seven local government areas.
In Parliament yesterday she would not rule out a lockdown for Greater Sydney.
"The New South Wales government will not hesitate to go further and harder if we have to," the Premier said at Macquarie Street.
"And I really want the public to be prepared. We've not experienced this level of transmissibility in this variant previously and it has no doubt impacted our response."
The Bondi cluster will be NSW's biggest COVID cluster so far. Here's how it compares to the other outbreaks .
The Delta strain outbreak in Bondi is set to become New South Wales's biggest cluster, but it's not all bad news with two major factors meaning it could be controlled in a similar time to other clusters.Yesterday, the Bondi cluster count was at 141 cases, so today, the case numbers are likely to surpass the Northern Beaches cluster, which peaked at 151 cases.
