Three residents of an aged care home in Sydney's north-west have tested positive to COVID-19 overnight.
Two of the three infected residents, who reside at the SummitCare nursing home in Baulkham Hills, have now been transferred to Westmead Hospital as a precautionary measure.
All three have received COVID-19 vaccinations.

The new cases come after the nursing home was placed in "full lockdown" on Friday after an unvaccinated nurse who worked there tested positive.
A second nurse at the home tested positive yesterday.
In a statement, Summit Care said the three infected residents were not showing any symptoms at this stage and were "in good spirits".
All of the residents' families have been contacted and are being provided with updates on the situation.
Deep cleaning of the home and regular testing of residents and staff continues.
Of the facility's 149 residents, 96 per cent are vaccinated.
"The fact that the affected residents are showing no symptoms at this stage shows their early vaccinations have worked," a Summit Care spokesperson said.
However, the latest cases have highlighted gaps in Australia's vaccination of health care workers, with many aged care nurses and staff not receiving the jab.
On Monday, Prime Minister Scott Morrison announced that COVID-19 vaccines would become mandatory for aged care workers.
However, all of those workers are not expected to have their first dose until mid-September.
Most of Australia's almost 1000 virus-related deaths have been in aged care homes.
