 Australia has secured about one million additional doses of Pfizer's COVID-19 vaccine that will start arriving on Sunday night, Prime Minister Scott Morrison said. Australia secured one million more Pfizer vaccines from Poland, a major help to the country's slow vaccine rollout. The doses will start to arrive on Sunday, said Prime Minister Scott Morrison, and will be targeted for Australians aged 20 to 39. Particularly in Sydney where cases have spiked to record highs. The state of New South Wales entered a snap lockdown to control the spread of the Delta variant in regional towns. Authorities have stepped up their measures for any residents breaking the stay-at-home orders, or lying to contact tracing officials, with fines raised up to US$3,700. As Sydney enters its eighth week of lockdown, hundreds more defence personnel will be deployed to enforce the lockdown rules. Several towns in the state are also under stay-at-home orders due to people breaching the city lockdown and spreading the virus.
