Sun Cable was proposing a High Voltage Direct Current (HVDC) undersea cable to Indonesia and Singapore. They went into administration last year but I think came out of it with new ownership. The cable has to pass through one of the worlds busiest shipping channel (Singapore strait) and areas of high seismic activity and the distances aren't trivial. Australia is very remote and there aren't many large power consumers in our vicinity and a lot of capital needs to be raised. The Darwin to Singapore route is about 9 times longer than the current longest undersea power cable.
