MELBOURNE (AFP) - Thousands of Australian Rules football fans were told to self-isolate and get tested for coronavirus on Wednesday (May 26) after an infected spectator attended a match in Melbourne and the city raced to avoid another lockdown.
Australia's second-biggest city is scrambling to contain a growing Covid-19 outbreak, with 15 cases identified so far, including one who attended the clash between Collingwood and Port Adelaide that drew a crowd of more than 23,000 to the famed Melbourne Cricket Ground on Sunday.
The Australian Football League (AFL) said thousands of fans who sat near the positive case were now required to self-isolate until they received a negative test, while health officials were reviewing closed-circuit television footage to determine if others had also been impacted.
The stadium is one of a growing list of venues across Melbourne visited by positive cases, leaving state health officials rushing to test and trace across the city of five million that endured a devastating four-month lockdown after an outbreak last year.
AFL games scheduled in Melbourne for the coming weekend are currently allowed to go ahead with fans at up to 85 per cent capacity, but government officials warned public events could yet face fresh restrictions.
"We are concerned about the number and the kind of exposure sites, and the next 24 hours are going to be critical if we are going to have to make any further changes," acting Victoria state Premier James Merlino said.
Limits on gatherings were introduced and masks made mandatory indoors on Tuesday as the virus cluster grew, while New Zealand introduced a temporary pause on its travel bubble with the state.
Victoria had not recorded any locally acquired coronavirus cases for about three months before the latest cases, which are believed to be linked to a traveller who returned from overseas and became infected while in hotel quarantine.
Australia has largely been successful in curbing the spread of the virus, in part through strict border controls that limit flights from overseas and require most travellers to isolate for 14 days on arrival.
But repeated failures of the quarantine system and a sluggish vaccine roll-out have prompted critics to attack the conservative government for an apparent reluctance to address the ongoing concerns.
Australia - which has recorded about 30,000 cases and fewer than 1,000 deaths from Covid-19 - has so far administered about 3.7 million vaccination doses in a population of 25 million, but hopes to finish its vaccine roll-out by the end of the year.
