The isolation status of 12 cases remains under investigation. Some 63,000 tests were done in the past day and they picked up cases in people who were not symptomatic, something the premier said was good news. However, NSW Police Deputy Commissioner Gary Worboys said officers yesterday busted an office party after stumbling across a gathering while patrolling George Street in Sydney CBD.
