Directlink (Terranora) Interconnector is a mixed buried and above ground 59 kilometre (37 mi) High Voltage Direct Current (HVDC) electricity transmission cable route from near Lavertys Gap (28°34′15″S 153°27′8″E / 28.57083°S 153.45222°E), 5 kilometres (3.1 mi) Southwest of Mullumbimby, New South Wales and Bungalora (28°15′20″S 153°28′20″E / 28.25556°S 153.47222°E) & connected via a 3.5 km (2.2 mi) AC Overhead Transmission Line to the NorthEast to the Terranora Electrical Substation (28°14′28.3″S 153°30′12.7″E / 28.241194°S 153.503528°E) @ Terranora, New South Wales in Eastern Australia. The DC cables alternate between above ground in a galvanised steel trough and below ground with depths up to 1 metre.
