It comes as the state recorded one new case of coronavirus overnight.
The 68-year-old Queensland woman was diagnosed with the virus in the past 24 hours and authorities are still investigating the source of the infection.
Two historic cases have also been added to the state's total of 1,088 cases.
The hotspot declaration means anyone travelling from NSW or the nation's capital will soon be banned from entering the Sunshine State.
Queenslanders who return after travelling there will be sent to mandatory hotel quarantine for 14 days at their own expense.
