3-day lockdown

Premier Annastacia Palaszczuk said six of the cases were overseas acquired and four were community transmission, two of those were linked to the 26-year-old landscaper from Stafford who tested positive to the highly infectious UK strain on Thursday night.

ABC News reports two of the cases have an unknown origin.

Greater Brisbane will now go into a three-day lockdown as of 5:00pm today and masks will be mandatory.

This includes the Ipswich, Logan, Redlands, Moreton and Brisbane council areas.

"I know they will be some in Brisbane today asking 'why is this necessary? There is only one case. '" said Prime Minster Scott Morrison.

"Well, this isn't any ordinary case.

"This is a very special case and one that requires us to treat things quite differently until we know more and we will learn much in the next few days.

"What Queenslanders will be doing over the next few days, they will be doing not just for themselves and their own communities, but for the rest of the country.
