- Olivia Winnie Muranga and Diana Lasu are linked to the Queensland outbreak
- Ms Muranga works as a cleaner at Parklands Christian College in Park Ridge
- The school has closed after an infected cleaner worked on site for three days
Two teenagers at the centre of Queensland's coronavirus outbreak who travelled to Brisbane from Melbourne have been identified.
Olivia Winnie Muranga and Diana Lasu, both 19, arrived together in Brisbane from Melbourne via Sydney on July 21.
They were active in the community for eight days before both tested positive to COVID-19.
Ms Muranga is a cleaner at Parklands Christian College in Park Ridge.
The school's principal Gary Cully confirmed a coronavirus infected cleaner worked for three days last week.
'The staff member was on site last week and then rang in sick and then that's when the trace program started,' Mr Cully told The Courier Mail.
'As far as I'm aware they were not symptomatic while they were onsite and then called in sick the following day and then the next week were tested.'
The cleaner saw a doctor on Saturday, who said to get tested immediately, but they didn't do so until Monday.
Mr Cully said other staff have gone into isolation after the infected cleaner worked at the school.
The school closed for deep cleaning on Wednesday, with Mr Cully hopeful it will open next week.
'Our children and our staff are like family and we are doing everything possible to keep them safe now and in the future and that includes fully cooperating with the Metro South Public Health Unit,' he said.

Shopping centres, restaurants, a school, and a church they visited will shut while authorities scramble to conduct contact tracing.
Scores of the women's contacts will be forced to isolate, and aged care facilities in the Metro South Health region will re-enter lockdown.
The incident prompted Queensland Premier Annastacia Palaszczuk to announce all Sydneysiders will be banned from entering the state from Saturday.
'There will be a thorough police investigation here but now we have to act as a community and in the areas where the chief health officer says need to be closed, will be closed and I urge people in those areas when that list goes out later on today to please ensure that if you are feeling sick you must go and get tested,' she said.
Queensland residents returning will have to isolate in a hotel for 14 days at their own expense.
Queensland Chief Health Officer Dr Jeannette Young called the pair 'reckless' and said she was 'very disappointed'.
The teens travelled on flights VA 863 and VA 977. Queensland Health contact tracers are identifying close contacts from those flights.
Health Minister Steven Miles said there was a large amount of contact tracing that needed to be done with the community as well.
'These young women have gone about their business within the communities that they live in and so there will be a large amount of contact tracing to be done, largely within it the Logan and Springfield areas, including shopping malls, restaurants and a church.'
One of the women attended the Orion Springfield Central in Ipswich, south-west of Brisbane, on Sunday where she dined at the Peak Thai restaurant about 6.30pm.
The pair's entry into Queensland is the subject of a criminal investigation, with penalties for lying on your declaration form incurring fines of $4,003 or six months in jail.
'Initial investigations indicate there were incorrect details on border declaration passes,' Deputy Police Commissioner Steve Gollschewski said.
'This highlights why you need to declare if you've been to Victoria where there's been a high instance of community transmission.
'You need to think about those around you - not just yourself.'
A 22-year-old woman who is an employee of YMCA Chatswood Hills Outside School Hours Care in Springwood also tested positive to COVID-19.
Both the school care service and the associated Chatswood Hills State School have been closed for cleaning.
There are now eight actives cases left in Queensland following three new cases on Wednesday.
Victoria recorded 384 new coronavirus cases and six more deaths between Tuesday and Wednesday's daily updates.
There are 4,774 active cases, including 414 health workers. The state has suffered 83 deaths in total, only one less than the rest of country combined.
A total of 206 people are in hospital, with 45 in intensive care.
