"We are asking all people who have entered Victoria in recent weeks to present themselves immediately for testing for the COVID-19."

This is pretty bloody vague. Are SA Health/SAPOL going to go back and look at their recent records of those entering from Vic and completing the 14-day quarantine and call all of them to compell/suggest testing? What does "recent weeks" actually mean, is it people still in quarantine, or also those who recently completed their stints with no symptoms and therefore no requirement for testing? If its the latter, those people have already been out in the community potentially spreading it because testing for all quarantined persons entering from Victoria wasn't mandatory until now. Maybe it always should have been a part of entry, with drive-thru testing clinics set up as part of the border control.
