A criminal investigation is underway into three women who returned to Queensland after lying about being in a covid hotspot.
They all arrived in Brisbane from Melbourne, via Sydney last week.
Two have tested positive to covid-19, a third is awaiting results.
Deputy Police Commissioner Steve Gollschewski says authorities are reviewing every aspect of the case to understand how the women made it across the border:
"Our early investigations indicate and we will allege that they have deliberately falsified records to get back into Queensland.
That is the focus of our investigation but we will do to get through that but what is really what important for us is that we look at our system and it is as good as it can be".
One of the girl's sisters - who did not travel to Melbourne - has subsequently tested positive.
Meanwhile, Health officials are pleading with people in Logan, Ipswich and Brisbane's south to get tested for coronavirus.
The women at the centre of the outbreak have visited many shops, restaurants and bars while infected.
People are already this morning waiting in long queues outside a community testing clinic at Parklands Christian College. at Park Ridge.
