The numbers of mystery cases and new cases not in isolation will determine whether Sydney can get out of lockdown as planned on Friday.
NSW Health Minister Brad Hazzard on Tuesday morning said the number of unlinked - or mystery - cases was more important than the number of total cases.
'There's a whole team of health officials... they're looking at the numbers, whether they're linked or unlinked, and also whether there's unknown chains of transmission,' Mr Hazzard told RN Breakfast.
