Kmart Botany has been closed for deep cleaning after a worker tested positive for Covid-19.
The teenager who recently tested positive for Covid-19 worked two shifts at the Botany Kmart last week despite advice from their sibling's school for all households to stay home until they got a negative test.
They were at Kmart on Friday the 19 February and Saturday the 20 February between 4pm and 10pm.
Amy Williams is at Kmart in Botany.
