A vigil was held on Friday in Brisbane at King George Square for a Biloela family who has languished in immigration detention for three years.

Greens Senator Larissa Waters and former Labor Senator Claire Moore also participated, calling for Minister Karen Andrews to release the family and let them go back to Biloela.

Their three-year-old daughter Tharnicaa is currently in Perth hospital being treated for sepsis as a result of untreated pneumonia.

Queensland Premier Annastacia Palaszczuk called on the Federal Government to make a call on the future of the family.
