Five hundred primary school kids are plunged into 14 day isolation after worrying classroom cluster grows to FOUR infected children

Students and staff at a primary school in Sydney's eastern suburbs have been plunged into isolation after four pupils tested positive to coronavirus.

All 550 students at South Coogee Public School have been deemed close contacts after two additional students tested positive to Covid-19 on Sunday. 

The school previously sent a letter to parents on Friday to inform them that all staff and pupils needed to isolate under further notice, after an initial two pupils tested positive. 

The students who tested positive on Sunday are close contacts of the two previously reported cases at the school, bringing the total number of positive tests to four.

NSW Health has updated its advice following the additional cases and because there has been a number of interactions between students in different year groups. 

About 550 students at South Coogee Public School have been asked to self-isolate for 14 days, regardless of a negative test result.  

The primary school has been closed from Saturday to undergo deep cleaning, with contact tracers interviewing those who have been affected. 

The school said they would work closely with NSW Health to ensure safety precautions were swiftly implemented.   

The South Coogee cluster comes as Emanuel School in Randwick sent an email to parents on Sunday evening to notify them one of its student had tested positive.

'All secondary staff and students are asked to self-isolate until you receive further advice', the email read.

'All primary staff and students should monitor for symptoms and if symptoms develop, be tested and self-isolate until a negative test is received.'

The school will be non-operational from Monday June 28 to allow for deep cleaning and contact tracing to take place. 

Mount Sinai College, a primary and pre-school in Maroubra, also sent out a message over the weekend after a member 'of the school community' tested positive. 

Parents were informed through an email the school would be non-operational from Monday June 28 for the on-site attendance of staff and visitors.

Contact tracing and deep cleaning will also take place at Sinai College, with all staff and students at the school asked to self-isolate until further notice. 

It is believed the positive case is a parent linked to the Bondi cluster. 

Last Tuesday it was reported by NSW Health that a nine-year-old student from St Charles' Catholic Primary School in Waverley had contracted the virus. 

This particular case has not been linked to any previous clusters.  

A seven-day lockdown - which began on Friday at 11:59pm - has been announced as the city deals with a Covid-19 outbreak which emerged in the eastern suburbs in mid-June. 

Those who live or work in the Woollahra, Waverley, Randwick and City of Sydney council areas are required to stay-at-home as NSW recorded 30 new locally-acquired cases in the 24 hours to 8pm on Saturday. 

All have been linked to the Bondi outbreak, which now stands at 110, with 11 of the new cases in self-isolation throughout their infectious period.

Chief Health Officer Kerry Chant said 10 of Sunday's new cases were linked to Great Ocean Foods in Marrickville, bringing that cluster to 11.

One case linked to the seafood distributor is a domestic flight crew attendant with Virgin Australia who tested positive on Saturday night.  

NSW residents have been warned case numbers are expected to rise over the next week as the highly contagious Delta variant spreads in the community. 

Premier Gladys Berejiklian expects tests of people currently in isolation will return positive results to the virus over the next few days. 

'We expect household contacts to develop the virus,' Ms Berejiklian said on Friday.

'Our aim is to make sure that we get on top of any potential spread and that we also get on top of any chains of transmission'.

Greater Sydney was placed into lockdown on Saturday after escalating restrictions were enacted over several days across the city's centre and east.

Residents in the lockdown zone are only allowed to leave home for work that can't be done at home, to shop for essentials, for exercise, to seek medical care or for care-giving or compassionate reasons.

Those who have been identified as confirmed cases or close contacts of confirmed cases and are in self-isolation should not leave their house for even these reasons. 

Anyone in regional NSW who has been to Greater Sydney since June 21 is also being asked to stay home for the lockdown period. 

Dr Chant said she was confident the lockdown - scheduled to end at 11.59pm on July 9 - would be sufficient to bring the outbreak under control. 

The lockdown applies to residents who live or have worked part-time or full-time in the hotspot suburbs in the past two weeks
