Worst NSW postcodes for Covid infectious activity as Delta takes hold

At least four NSW postcodes now have more than 400 active Covid cases. It can now be revealed the hotspot locations, which are keeping LGAs and the state in lockdown. Full list.

Sydneysiders have continued to be horrified by the rising Covid numbers gripping the state - recording one of its worst days since the pandemic began on Tuesday with 919 new cases.

Sydney has been in lockdown since June, after a limousine driver in the eastern suburbs, who had been transporting international flight crews, tested positive to the Delta variant.

After spreading through the eastern suburbs via Westfield in Bondi Junction, the outbreak moved to the city’s west.

Then a June birthday party in the southwestern suburb of West Hoxton then became a superspreader event, causing 45 positive linked cases, and led the NSW government to launch stay-at-home restrictions for residents in three eastern suburbs local government areas and Greater Sydney.

By June 26, Greater Sydney, the Blue Mountains, Central Coast and Wollongong were thrown into lockdown.

Tracking data showing the location of active COVID-19 cases in NSW is crucial for health authorities in the fight against the outbreak.

The data from NSW Health has led to stricter lockdown restrictions for those hardest hit Sydney council areas in the city’s west and southwest, and is likely to eventually determine when restrictions might ease.

These are the postcodes which have the highest number of active cases as of August 22, with people moving the most around while infectious, potentially spreading the deadly virus to loved ones and the wider community completely unawares.

Casula’s postcode recorded 324 active cases of Covid to August 22, as cases rise during the current lockdown.

The suburb was listed in July as an area of concern, with people shopping in the supermarket giant while suffering from Covid.

More recently, a person who has tested positive to COVID-19 was listed as visiting the Coles at Casula Mall where hundreds of shoppers were potentially exposed.

The suburb’s Crossroads Hotel, linked to a cluster last year, was incorrectly named by NSW as an exposure site in July. The department issued a statement in response to the mixup, stating Strathfield’s Crossways Hotel was the source of the cluster of cases.

The suburb’s postcode recorded 335 active cases over the weekend, after it was named by NSW Health as an area of concern last month.

The Blacktown suburb has seen cases rise even after harsher lockdown restrictions were brought in to contain the outbreak.

The suburb also hit headlines in January when NSW Health listed the Grange Buffet at Blacktown Workers Sports Club an exposure site.

5. FAIRFIELD

Fairfield’s postcode recorded 342 active cases, and was just a few weeks ago called the “epicentre” of the outbreak.

NSW Premier Gladys Berejiklian said Fairfield was the state‘s biggest area of concern, before Canterbury-Bankstown claimed the title in recent weeks.

The area reached a peak of 54 cases in a day in July before dropping due to harder lockdown regulations, which limited retail shopping and the ability for active cases to move around the community.

4. MERRYLANDS

The suburb of Merrylands’ postcode recorded 433 active Covid cases as of August 22, with NSW Health worried the suburb is continuing to generate a lot of cases.

The Parramatta suburb was flagged by Premier Gladys Berejiklian as a suburb of “considerable concern”.

The area has a growing number of exposure sites, including the popular Trims Fresh farmers market.
