Three Queensland suburbs are on high alert after a positive coronavirus case visited the areas.
Anyone who has been in the Ipswich suburbs of Goodna, Redbank and Redbank Plains over the last two weeks must isolate and get tested if they begin to develop symptoms, Queensland Health said.
The state recorded zero cases on Monday and has 30 active cases.
Queensland’s tough border policy has been in the spotlight in recent weeks and drew criticism from Prime Minister Scott Morrison after several out-of-state family members initially failed in applications to attend funerals in Queensland.
The state’s chief health officer, Dr Jeannette Young, confirmed she had received death threats and online trolling over the stringent measures.
"It has taken an enormous toll on me, but then this has taken an enormous toll on nearly every single person in our community," Dr Young said on Monday.
On Friday, an emotional Premier Annastacia Palaszczuk told reporters decisions on the border were out of her hands.
Ms Palaszczuk has come under heavy fire from Mr Morrison, NSW Premier Gladys Berejiklian and the state's opposition Liberal National Party over her government's strict health policies.
She has since promised to speed up the application process for compassionate exemptions, but she's holding firm on borders, saying she will stake her political future on keeping them shut.
"Now if it means I have to lose the election, I will risk all that if it means keeping Queenslanders safe," she told reporters.
Ms Palaszczuk accused political opponents of trying to "tear Queensland apart" because the health response to COVID-19 had left the state in better situation than others.
"In Queensland people are going about their normal jobs as if almost life was back to normal," she said.
"I'm not going to risk all of that, why would anyone risk that?"
