Health authorities in Queensland are scrambling to track down all contacts of two Brisbane friends who tested positive for coronavirus, amid fresh concerns about the outbreak growing.
A week out from Easter, Queensland Health revealed on Saturday night one of the men, aged 26, held a house party while he was waiting on his test result, despite instructions to self-isolate.
About 25 guests attended the Strathpine gathering and all have been ordered into quarantine and are being tested for COVID-19.
Queensland Health are also tracking down people who may have come into contact with the men at 24 exposure sites, and asking them to isolate and get tested.
The cluster has sparked a lockdown of Brisbane City and Moreton Bay council area hospitals, aged care facilities, prisons and disability services providers.
NSW, Victoria and the ACT have also declared those two council areas as hotspots and all travellers arriving from there must self-isolate and get tested upon arrival.
Western Australia is requiring all visitors from Queensland to self-isolate for 14 days, with the new directions also applying to those who arrived from Queensland earlier on Saturday.
Tasmania is only warning Brisbane and Moreton Bay travellers to get tested if they become ill, while South Australia and the Northern Territory have not changed their travel rules.
Earlier on Saturday Premier Annastacia Palaszczuk said there was no evidence of widespread community transmission.
"We are very comfortable where things are at the moment, and Queensland is responding incredibly well, so if everyone keeps up their testing and the contact tracing we're very comfortable with where we are," she told reporters.
Prime Minister Scott Morrison urged states and territories to be balanced and "proportionate" in their response to the outbreak.
He says the ongoing vaccine rollout has changed "risk calculations" and he's confident the Queensland government has control of the situation.
"The Queensland government's got this, they've got a strong tracing system, they've got a very strong public health system there in Queensland. I have a lot of faith in that, I've seen it in action before, and I think we've got to backup people to keep this under control, and I have no doubt the Queensland government will do that."
The Brisbane cluster has also put a number of Easter sporting fixtures in doubt amid concerns about travel restrictions.
Melbourne's Good Friday NRL clash with Brisbane is under a cloud while the Gold Coast Suns' return to Queensland from Victoria is up in the air.
Canterbury are already in Brisbane for their NRL clash with the Broncos on Saturday night, while Parramatta have been there since March 12.
