Prime Minister Scott Morrison has acknowledged the never-ending mishaps the nation has faced with covid and particularly, the Delta strain.
On Wednesday's covid update, NSW Premier Gladys Berejiklian revealed the reliance on the lockdown strategy is due to the very low supplies of Pfizer available at vaccination hubs.
Berejiklian added that due to the low vaccination rates and severity of the delta strain, the lockdown is unlikely to end until the community case numbers near zero.
