* Australia's technical advisory group for immunisation will undertake a "continuous review" of all COVID-19 vaccines in domestic use after the death of a 48-year-old NSW woman who had the AstraZeneca jab.

* Therapeutic Goods Administration investigators have concluded Genene Norris's blood clots with low platelet count was likely linked to her vaccination. She had several chronic health conditions when she received the jab on April 8.

* Ms Norris was the third Australian case of its type, with the first two still in hospital. Some 885,000 AstraZeneca doses have been administered in Australia so far.

* Chief Medical Officer Paul Kelly said "people should be cautious about jumping to conclusions" over the case.

* Health Minister Greg Hunt urged Australians not to refuse vaccinations, saying a vaccine still offers the greatest protection against coronavirus.

* NSW Health says COVID-19 may have been transmitted within hotel quarantine, after two family groups who arrived from different countries on different days were shown to have the same viral sequence.

* The groups stayed in adjacent rooms on the 12th floor of the Adina Apartments Hotel. The cases may have to be reclassified as locally acquired.

* Victoria recorded its 50th day in a row with no locally acquired cases. Its two new cases in quarantine are a man aged in his 40s and a woman in her 30s. The state's total number of active cases stands at 10.
