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 / -28.57083; 153.45222 (Directlink - Mullumbimby Static Inverter Plant)), 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 / -28.25556; 153.47222 (Directlink - Bungalora Static Inverter Plant)) & 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 / -28.241194; 153.503528 (Essential Energy - Terranora Electrical Substation)) @ 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.

It is one of the two interconnections used to trade electricity between New South Wales and Queensland (the other is the 330 kV Dual Circuit Queensland – New South Wales Interconnector (QNI)).[1]
