Queensland Health is trying to track down people who attended a popular Brisbane nightspot over the last few days, amid concerns they came into close contact with a 22-year-old university student with coronavirus.

"As a precaution, we are asking anyone who attended Friday's Riverside in Brisbane City from 6:00pm Friday afternoon [until] 11:00pm Monday evening, who becomes unwell to contact 13 HEALTH (13 43 25 84) and advise that you were at the venue during these times," a statement from Queensland Health said.

Queensland chief health officer Jeannette Young said if patrons had any symptoms they needed to be tested.

"The individual attended there for four hours and had fleeting contact with a lot of people," she said.

"That's why it doesn't require people to go into home quarantine."

But Dr Young said it was a different situation for University of Queensland (UQ) students who had attended class with the patient.

Queensland Health is contacting people who had close contact with the man on a UQ campus.

"Those students at the University of Queensland are asked to go into home quarantine because there are a significant number who had spent more than two hours in a room with the student who had been positive," Dr Young said.

"The requirements for people to go into quarantine are if you have 15 minutes or more of continuous close contact with one person, so that's usually in a home setting, or if you had more than two hours in a room — which is why the UQ students are being asked to go into home quarantine."

The man was confirmed with COVID-19 on March 10.

The news followed the announcement of two other new cases of coronavirus in Queensland.

Queensland Health said a 32-year-old woman who recently returned from the US was now in isolation at the Gold Coast University Hospital.

A 31-year-old Gold Coast man who had close contact with her is also in isolation at the same hospital.

Contact tracing for both cases is underway.

Dr Young said people most at risk are those over 60 with co-morbidities and Aboriginal and Torres Strait Islanders.

"Those are the people I'm most concerned about.

"We have to prevent transmission to those vulnerable people," she said.

Regional university campuses closed

Meanwhile, Southern Cross University (SCU) closed two of its campuses for the day on Wednesday following detection of the first coronavirus case in regional Australia.

The Lismore campus in northern NSW and Gold Coast campus in Queensland were put in lockdown to stop any potential spread of the virus after a staff member tested positive.

However, the campuses have reopened today.

An estimated 8,000 students were forced to study at home during the closure but were not required to self-isolate.

A university employee from the Philippines attended a series of workshops at both campuses between March 2 and 6 before falling ill.

The male staff member returned a positive test for coronavirus on Tuesday but told the university his symptoms had subsided the previous day.
