wikipedia so cannot attest to the reliability but here is some more information on Loy Yang. Doesn't look like they will need our coal unfortunately....

Four giant bucket-wheel excavators, called dredgers, operate 24 hours a day in the Loy Yang open cut mine, mostly feeding coal directly to the boilers via conveyor belt, 18 hours of reserve supply is held in a 70,000 tonne coal bunker. Each year approximately 30 million tonnes of coal are extracted from the open pit. The open cut coal mine pit is about 200 m (660 ft) deep, 3 km (1.9 mi) and 2 km (1.2 mi) wide at its widest. It is estimated that at current rates of extraction there are sufficient deposits of coal in the entire Latrobe Valley region to last 1300 years.

Carbon Monitoring for Action estimates this power station emits 14.40 million tonnes of greenhouse gases each year as a result of burning coal.[2]
