It appears the power supply is external (meaning its a power pack you plug in and a dc cable plugged into the monitor). I guess maybe they package a different power supply for countries like Aus/NZ, or the power supplies are 'universal' (110-250V 50-60Hz). You would have to ask. If its the latter, it will work by may require an adaptor plug. An adaptor plug should only be used with universal or same power system plugs, not like idiot Americans I've seen at uni trying to plug their 110V 60Hz appliances into a 240V 50Hz outlet with one!
