LATEST COVID-19 DEVELOPMENTS:
* Metropolitan Perth and the Peel region will go into a three-day lockdown from midnight on Friday after a hotel quarantine outbreak led to community transmission.
* Anzac Day dawn services will be cancelled and all people in the affected regions must wear masks when leaving their homes from 6pm on Friday.
* "I know this is hard to take and I wish we didn't need to be doing this," Mr McGowan told reporters. "I hope we can keep it to three days only".
* Shops and venues will close for three days, though weddings and funerals will be allowed to proceed with a maximum of 100 guests all wearing masks.
* Mr McGowan has asked Prime Minister Scott Morrison for international arrivals into Perth to be temporarily halved from just over 1000 a week to just over 500.
* Premier Mark McGowan says the lockdown is a necessary measure after two people spent days in the community while infectious. One is a man who stayed in hotel quarantine before flying to Melbourne. He tested positive in Melbourne so is counted as a Victorian case. He completed 14 days' quarantine at Perth's Mercure Hotel before returning to Melbourne on Qantas flight QF778 on Wednesday.
* The second infected person is a woman the man stayed with in Perth after he left hotel quarantine. Her positive test result came through on Friday afternoon, Mr McGowan said.
* The Victorian man's positive test result has ended the state's eight-week run without a locally-acquired case.
* Australia has left the door open to even harsher inbound travel restrictions for India as hotel quarantine cases continue to rise.
The federal government is cutting repatriation and direct flight arrivals by 30 per cent with India in the grips of a catastrophic outbreak.
* Australia's sluggish immunisation program continues to come under fire with national cabinet agreeing to a major reset in a bid to salvage its progress.
* AstraZeneca jabs will be available for people over 50 at state and territory vaccination centres as well as respiratory clinics from May 3, before being sent to all GPs from May 17.
* The Northern Territory has recorded another 13 COVID-19 cases in quarantine, adding to the 20 already recorded in the past week. Health officials have warned there may be more infected returned overseas travellers among the passengers on recent flights from India.
* The Queensland government will restart the COVID-19 vaccine rollout in the Torres Strait Islands next month amid concerns about the AstraZeneca jab.
* A group of Sydney dock workers are sweating on the results of their coronavirus tests after boarding a ship now found to have been carrying infected sailors. The Inge Kosan, an LPG tanker, was docked in Port Botany for a day from March 31 after arriving from the Papua New Guinea capital of Port Moresby.
