Queensland's border reopening with NSW could be in jeopardy after that state recorded another mystery COVID-19 case and traces of the virus were found in sewage near Brisbane.
Premier Annastacia Palaszczuk says she'll take advice on Friday from chief health officer Jeannette Young, who is closely watching developments south of the border.
"I have to do what I have to do to keep Queenslanders safe," Ms Palaszczuk said on Thursday while campaigning for re-election on the Gold Coast.
"I am not diverting one step away from that so we will listen to the health advice."
Ms Palaszczuk said she expected to meet Dr Young when she returned to her Brisbane office on Friday.
November 1 was previously flagged for a potential reopening of the border between the two states but only if NSW had control of the virus in the community.
It comes as Queensland health officials on Thursday found traces of the virus during sewage testing at a treatment plant in Ipswich, west of Brisbane.
Dr Young said the result was concerning as it may indicate there undetected COVID-19 cases in the community.
The Ipswich wastewater facility had recorded several weeks of negative results after a series of locally acquired cases known as the Brisbane Youth Detention Centre cluster were brought under control.
Queensland recorded no new COVID-19 cases in the 24 hours to Thursday morning.
Five cases remain active.
