Course and features
The river rises below Mount Grundy on the eastern slopes of the Great Dividing Range southwest of Tia, and flows generally northeast before reaching its confluence with the Apsley River, northwest of Tia. The river descends 905 metres (2,969 ft) over its 52 kilometres (32 mi) course; spilling over the Tia Falls in the Oxley Wild Rivers National Park.
The river is transversed by the Oxley Highway.
Previously the river was known as Crimps Creek and also Crokers River which John Oxley had named this stream, in honour of the First Secretary of the Admiralty.
The country above the Tia Falls is a rich grazing area used for rearing livestock. The upper parts of the Tia River have remarkable cool temperate rainforests, with unusual species such as Southern Sassafras, White Mountain Banksia and Black Olive Berry.
Tia River is a general trout stream.
