While Australians wait for the Pfizer vaccine to become more available, NSW's coronavirus outbreak continues to worsen with 50 new cases reported on Saturday.
Greater Sydney is under the toughest COVID-19 restrictions in over a year with Premier Gladys Berejiklian pleading for honesty towards contact tracers and obedience in relation to lockdown rules.
"The length of this lockdown is up to each and every one of us," she said.
"When people don't tell us the truth or withhold from us what's happening, it just lasts longer.
With 37 of the latest cases infectious in the community for at least part of the time before moving into isolation, Ms Berejiklian warned the situation would worsen before getting better.
The state's chief health officer Kerry Chant urged residents to get vaccinated as soon as possible and highlighted that no one who has had two vaccine doses is in hospital.
As vaccination demand increases, arrivals of Pfizer doses are set to rise to about one million a week from July 19 and 4.5 million are expected to be available over August.
Prime Minister Scott Morrison has flagged an advertising campaign to coincide with the boost.
Pfizer's availability and changing advice on the AstraZeneca jab have hampered the rollout, sparking criticism of the government's vaccine portfolio.
Opposition Leader Anthony Albanese said Mr Morrison announced the reinforcement of Pfizer supplies only after coming under pressure following six days without a public statement.
"We're not seeing huge increases at all in spite of the government spin," he told reporters in Queensland.
Another 1300 GPs will join the rollout to deliver Pfizer doses, with the prime minister confident it can be completed by Christmas.
With 10.6 per cent of people over 16 fully vaccinated with two doses, Australia is well behind most of the developed world.
Labor has been calling for a major advertising campaign to bust vaccine hesitancy and promote the benefits of being immunised against coronavirus.
Shadow treasurer Jim Chalmers said the government was quick to spend $1 billion on self-promotion but refused to spend thousands of dollars on countering misinformation.
"We also should have a dedicated, serious, genuine, public information campaign to deal with vaccine hesitancy," he said.
Victoria and Queensland did not record any local COVID-19 cases on Saturday but reported three and five overseas-acquired cases respectively.
There are concerns in Tasmania after a healthcare worker left the state on July 2 and two days later, tested positive in London.
Officials say there is no evidence the person contracted COVID-19 or was infectious while in Tasmania.
However a list of sites they visited has been publicly released as a precaution.
Police resources have been beefed up on Victorian border with NSW, with more than 300 officers involved in patrolling by road and air, traffic management, spot checks and vehicle intercepts.
