They are McDonnell Douglas 500N type Helicopters, Rego No = VH-INY & VH-EPZ (may be more).
They are on loan by Endeavour Energy to check power lines in areas including Blue Mountains, South Coast, Sydney West, Hawkesbury (NSW to the Vic border).
These Helicopters are owned by Gunn Resources Pty Ltd according to Regosearch.com.
What makes these helicopters unique is the fact they don't have a tail rotor and sound similar to a washing machine or a strange vacuum cleaner (well, i think they do).
