Redlands MP Kim Richards congratulated residents on Sunday for their calm response to the news of the case.
COVID-19 testing opened on Russell Island at 3.30pm on Saturday and more than 150 tests had been conducted by the end of the day.
Chief Health Officer Jeanette Young commended the actions of the woman in her 60s who tested positive for the virus.
"After hearing all the messages about 'if you can't social distance, wear a mask', she had been doing that, and I'm sure that will stand that community in good stead," Dr Young said.
"It is really important for the next week at least that anyone on Russell Island who has any symptoms at all comes forward and gets tested."
The Russell Island case was thought to be linked to a current cluster of cases at Wacol.
The Public Health Unit was contacting identified close contacts of the woman.
