NSW Health released an exposure site alert for Tea Gardens Hotel in Bondi Junction, with anyone who attended the pub from 7.30pm until closing last Saturday night (October 23) now considered a casual contact.
The venue has been linked to at least 10 confirmed COVID-19 cases.
Anybody who was there must immediately get tested and self-isolate until a negative result is received.
A man in his 40s from Newcastle has died at John Hunter Hospital with the virus, NSW Health said.
A man in his 60s from western Sydney also died at the city’s Royal Prince Alfred Hospital.
Both had had their first dose of a vaccine and had “underlying health conditions”, officials, said.
A man in his 80s – who was fully vaccinated – from south-western Sydney died at Liverpool Hospital, where he caught the virus.
There are currently 418 COVID-19 patients admitted to hospital, with 97 people in intensive care, 43 of whom are on ventilators.
Most are unvaccinated.
There were 89,875 COVID-19 tests reported to 8pm last night.
The state has now fully vaccinated 87 per cent of eligible residents, while 93.5 have received a single dose.
Earlier in the week, Health released an exposure site alert for City Gym at Darlinghurst, with 15 cases linked to the facility.
Only fully vaccinated people were able to go to the gym under the current COVID-19 restrictions with authorities confirming cases either trained at the gym while infectious or caught the virus in the gym itself.
