In the men's draw, the Sydney Swans - who played in Brisbane just last week - are expected to clash with the Adelaide Crows at the SCG on Saturday.

Chief Health Officer Jeannette Young said the 26-year-old developed symptoms on Monday but it is not yet known how he became infected.

"The first reason is you want to be able to concentrate on the contact tracing, and secondly, we are seeing large numbers of positive cases that are coming in", she said.

"Information will be available later today and we will put that on our website".

Premier Annastacia Palaszczuk confirmed a man has tested positive for coronavirus and is a close contact of the Brisbane man reported on Friday.

Ms Palaszczuk said at the moment Queensland would not be placed under another lockdown.

It was revealed overnight that the strain the man contracted is that of the highly infectious United Kingdom variant, which was linked to a previous positive case, a doctor at Brisbane's Princess Alexandra Hospital.

Five more cases were reported in people returning from overseas.

The man's infection of the United Kingdom strain has been linked to a doctor who treated COVID-19 patients at Princess Alexandra Hospital.
