The ACTFR was requested by Powerlink Queensland to undertake an assessment of the flora and fauna values and potential impacts of the proposed installation of an underground 275 kV transmission line (hereafter underground line) to be placed along Crowleys Creek, Cairns. This proposed development is part of the construction of the larger Chalumbin to Woree 275 kV transmission line.

Crowleys Creek is located in the new suburb of Forest Gardens, approximately 6 km south of the Cairns city centre. The creek is ephemeral and runs from the eastern escarpment of the Wet Tropics World Heritage Area into Trinity Inlet. The section of Crowleys Creek under consideration (hereafter the creek) is approximately 2 km long, running from a Cairns City Council storage tank to the Bruce Highway. Just prior to the Bruce Highway for approximately 650 m, the creek runs alongside an outlying vegetated topographic feature known as Red Hill. The woodland vegetation at this point forms part of the riparian system along the creek. From the Bruce Highway the watercourse has been cleared and diverted until it reaches the mangrove vegetation surrounding Trinity Inlet.

The vegetation surrounding the creek has been largely cleared. Abutting the south bank of the creek is a new housing subdivision (Forest Gardens) which is currently being developed on land previously under sugarcane. On the northern bank of the creek, there is a mosaic of riparian woodland vegetation (where the creek passes alongside Red Hill), cleared vegetation and housing development. Remnant riparian rainforest vegetation occurs intermittently along both the northern and southern high banks and within the creek system.

The underground route being considered is from a point just west of the water tank crossing the creek twice in the first 200-300 m before continuing for most of its length (1.5-1.8 km) along the northern bank. The construction of the underground line will require a permanent 20 m clearing to be created and maintained once the line is installed. This report examines the environment values for flora and fauna along the proposed route and addresses potential impacts of the development on these.
