The all-clear was given for day three of the Boxing Day Ashes Test to start on time after Australia and England players all tested negative for coronavirus.
There had been a scare ahead of the second day of the third Test in Melbourne when a member of the tourists' family group returned a positive COVID-19 result.
The England players and management were forced to remain at their hotel while they awaited their test results, before being given the green light to travel to the ground, with play starting half an hour later than scheduled.
Both sets of players took PCR tests after the second day of play and Cricket Australia on Tuesday confirmed all tested negative, meaning there were no delays for the third day.
The England team's support staff and the family members who tested positive on Monday – reportedly six people in total – are in isolation.
Australia were well on course to retain the urn after reducing Joe Root's side to 31-4 in their second innings after two days of play, with England trailing by 51 runs and 2-0 down in the series.
