Three new cases of coronavirus have been found in the ACT, breaking Canberra's month-long bill of health.
The infections are all from the same household and linked to the Victorian outbreak.
Chief Minister Andrew Barr signalled a slowdown in easing restrictions, which was planned for later this week.
"Given the news today ... [This is] likely to be postponed, until we have a better understanding of the Victorian outbreak and the impact on the ACT," he said.
"In simple terms, we can not put the hard work of the community at risk by going too far too fast."
Australia has recorded 8,886 cases in total, with 1,293 active cases and 7,487 people recovered.
The national death toll is 106.
