The culturally-diverse suburbs in Sydney's south-west have become ground zero in the city's fight against Covid, as new data reveals the frightening rate the disease is taking a grip there. New South Wales Premier Gladys Berejiklian has voiced fears Covid is being spread by large families 'ignoring the rules' while numbers spike. In just a few days, south-western suburbs including Cabramatta, Edensor Park and Canley Vale have already become the number one infection hotspots in the city. NSW Health has detected 105 cases in the Fairfield local government area in this latest cluster since it broke out of Sydney's eastern suburbs and moved into the west. Of the 77 cases announced in Sydney on Sunday, 52 were in south-west Sydney, 11 were in central Sydney and 10 were in south-east Sydney. The culturally-diverse suburbs in Sydney's south-west have become ground zero in the city's fight against Covid, as new data reveals the frightening rate the disease is taking a grip there That figure compares to the four-week combined total of just 69 cases from the suburbs around Bondi since this outbreak began there on June 16. The white knuckle expansion rate in Sydney's south-west prompted renewed pleas from Ms Berejiklian for families there to heed the lockdown rules. But health experts fear the disease is ripping through the community there because the largely ethnically-diverse profile of the area creates unique challenges. English is not the first language in 71 per cent of homes in Fairfield, and 50 per cent of the area's 290,000 population were born overseas, according to council figures. New South Wales Premier Gladys Berejiklian (pictured) has voiced fears Covid is being spread by large families 'ignoring the rules' while numbers spike. Ms Berejiklian - whose parents emigrated to Australia from Armenia - fears extended family gatherings are accelerating the spread of the disease in the south-west. And she fears fluid family set-ups - where households regularly mix - will cause the current lockdown to be extended beyond its planned end on Friday. 'Can I say to the communities in those areas, many have a similar background to me, please don't mingle with family,' she said. WHICH SUBURBS ARE MOST AT RISK? Fairfield: 105 cases Canterbury-Bankstown: 73 Liverpool: 37 Georges River: 29 Cumberland: 19 Parramatta: 13 Campbelltown: 12 Strathfield: 10 Camden: 7 Penrith: 4 Blacktown: 4 *cases since June 16 Source: NSW Health Advertisement 'I haven't seen my parents since the lockdown started – it is hard. 'Can I say to everybody don't mingle with family, don't think it is okay to visit your cousins or have sleepovers. Please do not leave the house.' The premier's calls were renewed on Sunday by NSW Chief Health Officer Dr Kerry Chant. 'Please stay at home and that means staying within the one household,' she stressed. 'Do not leave that household setting and do not interact with other family members. 'And I know that that can be a difficult concept, given the closeness of family units, but at this point in time in responding to Covid, we need to keep the households as a discrete unit so we don't get that risk of further spread.' Victoria's chief medical officer Paul Kelly also echoed the concern and said he'd been told NSW was trying to get the message across to the communities. He added: 'I know New South Wales Health have been increasing their reach in many different ways into the multicultural community of south-west Sydney in particular where there is extraordinary and wonderful family groups that are very closely associating with themselves. 'In normal times that is a good thing but these are not normal times and so that message really is, stay within your own house and stay within your own family within that house and don't go out.' In just a few days, south-western suburbs including Cabramatta, Edensor Park and Canley Vale have already become the number one infection hotspots in the city, closely followed by suburbs in nearby Liverpool (pictured) However locals believe badly targeted ad campaigns, which don't do enough to keep communities updated with the latest lockdown restrictions, are to blame for the soaring case numbers. 'It's not about the culture,' Kate Hoang, federal president of the Vietnamese Community in Australia told the ABC. 'The south-western Sydney people are following the law and health advice, but sometimes there is definitely an information lag due to language barriers compared to people in other suburbs. 'We want to do the right thing.' Deputy NSW Police Commissioner Gary Worboys (pictured) said he hoped the different communities would work together to make sure the message got out promptly. Deputy NSW Police Commissioner Gary Worboys said he hoped the different communities would work together to make sure the message got out promptly. 'It's incumbent on everyone to make sure that people in their family, their friends, that may have difficulty with language or difficulty with the context of where we're at at the moment, to explain to them that they simply need to stay at home for this while, until such time as the risk has moved,' he said. The Fairfield local government area takes in 27 suburbs: Abbotsbury, Bonnyrigg, Bonnyrigg Heights, Bossley Park, Cabramatta, Cabramatta West, Canley Heights, Canley Vale, Carramar, Cecil Park, Edensor Park, Fairfield, Fairfield East, Fairfield Heights, Fairfield West, Greenfield Park, Horsley Park, Lansvale, Mt Pritchard, Old Guildford, Prairiewood, St Johns Park, Smithfield, Villawood, Wakeley, Wetherill Park and Yennora. The exploding figures in these suburbs have also spilled into the nearby local government areas too. Canterbury-Bankstown LGA which both borders Fairfield is also in the new danger zone as Sydney's second-most affected area, with 73 cases in this outbreak. Canterbury-Bankstown LGA which both borders Fairfield is also in the new danger zone as Sydney's second-most affected area, with 73 cases in this outbreak (pictured, Liverpool on Saturday) Randwick and Waverley which were the earliest affected suburbs in the current outbreak are the two next most affected, although recent case numbers have dwindled to almost nothing. But now Liverpool - which also borders Fairfield - is seeing a surge its case numbers that's left it as the fifth most affected area in New South Wales with 37 cases. It's followed by Georges River (29), Sydney (28), Bayside (24), Cumberland (19), Woollahra (19), Parramatta (13), The Hills Shire (13), Campbelltown (12), Sutherland Shire (11), Strathfield (10), Camden (7), Canada Bay (6), Burwood (5), Penrith (4), Blacktown (4), Hornsby (3), Willoughby (3), North Sydney (3), Inner West (3), Ryde (1) and Hunters Hill (1) from the metropolitan Sydney's LGAs. Mosman, Lane Cove and Northern Beaches are the only city LGAs not to record a single case in the last four weeks. Locals believe badly targeted ad campaigns, which don't do enough to keep communities updated with the latest lockdown restrictions, are to blame for the soaring case numbers.
