Almost 11 per cent of NSW residents aged 35-39 have been fully vaccinated, plummeting to 2.8 per cent for 16-19 year olds.
By contrast, Tasmania has managed to vaccinate 17.3 of its 35-39 year olds, the ACT 14.1 per cent and South Australia 12.8 per cent.
At the other end of the age scale, 40 per cent of over 70s in NSW have been fully vaccinated, while 77.5 per cent have had one dose.
An overall lack of supply of doses and shifting health advice over the AstraZeneca vaccine has hampered efforts to vaccinate under 40s. Until the Sydney outbreak, the Pfizer vaccine was preferred for under 60s.
But NSW has been left exposed by the lack of eligibility of most people under 40 years old, with that demographic driving the current surge in infections.
Under 40s have accounted for 65 per cent of new cases consistently over the 24 hours, week and fortnight to Thursday, NSW Health data show.
In the past fortnight, 394 Sydneysiders aged 20-29 were infected with the virus, and there were 359 infections among those aged 30 to 39, out of 1861 cases reported. The 20-39 demographic is typically the most likely to work in highly mobile and people-facing fields.
The trend is reflected across Australia, where 20-29 year olds make up for more COVID-19 cases than any other age group across the pandemic.
NSW Chief Health Officer Kerry Chant said the fact the majority of cases were among young people reflected the age demographic of the areas the virus was running rampant.
We have to also remember that the communities of south-western and western Sydney are also particularly young, she said. Many workers in south-western Sydney were essential which meant they were more mobile, she added.
