The Pioneer River, one of the few 'blue water' rivers in Queensland, and its main tributary, Cattle Creek, flow through the heart of the Pioneer Valley, from the Clarke Connors Ranges in the South and West to the Pacific Ocean at Mackay.
Access to the river is restricted by freehold ownership except for a few areas such as beside Edward Lloyd Park where access paths are maintained, including one just 50 metres from Melba House. Access in the Valley to the river is also possible at Pleystowe (boat ramp), Mirani (Platypus Beach - next to road bridge), Mia Mia (next to the road bridge), Pinevale, Gargett (next to road bridge), and Neem Hall (Finch Hatton). Canoeing, kayaking, platypus spotting and swimming are just a few of the activities the river provides.
Local residents fish the river for sooty grunter and barramundi - both species are renowned for their fighting ability. In addition, groups of Platypus (Ornithorhynchus anatinus) are frequently seen near their burrows on the northern bank behind Melba House. A wide variety of native and migratory bird species, including ducks, swans, pelicans and cormorants, and fresh water turtles also frequent the river.
