Health officials are asking more than 10,000 people who've arrived here from Melbourne to check whether they've been at Covid-19 hotspots in the city.
It comes as Victoria's Covid-19 cluster grows to 15 - with six new cases today. The travel bubble with the state was paused for 72 hours last night.
But with the MCG, nightclubs, restaurants and shops among a growing list of exposure sites - vigilance among recent arrivals here is being urged.
