Two more COVID-19 cases detected overnight in Queensland.

Queensland has been in lockdown since Monday, with residents of greater Brisbane disallowed from leaving home unless they were an essential worker, or needed to buy groceries or exercise.

Of the two new cases detected overnight, one was a vaccinated nurse.

The nurse is the second person to have caught COVID-19 despite getting the first jab and has sent the entire Princess Alexandra Hospital, where the nurse worked, into lockdown.

Queensland’s outbreak began over the weekend, with ten new cases confirmed on Monday.

The resulting lockdown has been set until Thursday, when it will be re-assessed.

Premier Annastacia Palaszczuk said 33,000 tests were done on Tuesday and the confirmation of just two new cases was encouraging.

“Fingers crossed, all will be looking good for Easter,” Ms Palaszczuk said.

However, NSW confirmed on Tuesday its own positive case linked to the Queensland cluster.

NSW Premier Gladys Berejiklian revealed a man in his 20’s had tested positive after sitting nearby a hen’s party that travelled to Byron Bay from Brisbane.

Ms Berejiklian announced new restrictions to try and curb any potential spread, with household gatherings limited to 30 people and venues forced to revert to the four square metre rule. Drinking while standing has also been banned once more.

WA has put up its hard border to Queensland this week, but has so far made no announcement about NSW.

The country’s latest outbreak comes ahead of the Easter long weekend, when many Australians travel interstate to see family.

It also coincided with the launch of the 800,000 half priced airline tickets, funded by the Federal Government.

Currently Western Australia has 11 active cases and has recorded a total of 938 cases..
