Queensland has reported just four new local cases of coronavirus.
Premier Annastacia Palaszczuk said the latest case numbers was "great news", after an eight-day lockdown in the state's south ended yesterday.
Ms Palaszczuk confirmed the taxi driver at the centre of the snap lockdown in Cairns is linked to a marine pilot who helps guide international ships to the coast.
"A lot of contact tracing is now happening … with those exposure sites," she said.
More than 26,000 Queenslanders were tested yesterday.
Earlier it was revealed that the driver at the centre of the city's shock snap lockdown could have infected hundreds of customers with COVID-19.
The unvaccinated 60-year-old driver was infectious at work for around 10 days, picking up between 20-30 rides each day, meaning the big question now for Cairns residents and the state is how many of those hundreds of rides have caught the coronavirus.
Queensland health officials have detailed a long list of exposure sites linked to the taxi driver, including the Brothers Leagues Club, a Woolworths and a 24-hour medical centre in Cairns.
9News this morning filmed hundreds of people queuing at local testing sites.
Yesterday Premier Annastacia Palaszczuk sent residents in Cairns and Yarrabah into three days of lockdown on the same day she lifted week-long lockdown restrictions for south-east Queensland.
Masks still need to be worn at all times in south-east Queensland schools, workplaces and outdoors.
For the next two weeks, up to 10 people can gather in homes.
Businesses can re-open with venue caps and weddings and funerals limited to 20 people.
Queensland reported nine new cases yesterday, including the Cairns taxi driver.
