Check first of all to ascertain that it is not a general power failure in the street. If it is a general failure please call the Energy Australia emergency number (the number is in the emergencies section). If the failure is localised to your unit, check to ensure that the circuit breakers have not tripped or the fuses blown, as these are the unit holders responsibility to maintain. If the circuit breakers and fuses are intact, you should contact your strata manager to have the matter inspected. If you have in your unit any working life-support equipment, such as a Dialysis machine, please call the emergency numbers given by the equipment supplier or medical team responsible for monitoring the patient’s condition.
