There may be a fault in the street
If you rent within a block of units it may be the Body Corporate that needs to be contacted for action.
There may have been an overload and the safety switch has been activated and needs resetting.
Unplug all appliances in the house. Reset the safety switch in the meter box. Plug in the fridge and turn on the powerpoint, check the safety switch. If the safety switch clicks off then you know that there is a fault with the fridge and you need to get it repaired. Otherwise connect one appliance at a time until the faulty appliance is located.

There is normally a copper valve on electric hot water systems and an overflow pipe – Pull up this lever until a flow of water starts coming out of the overflow pipe. Check the fuse in the meter box to make sure it is turned on.
Some units can be easily relit – others may require a tradesperson. Check to see if the valve on the gas meter is turned on.
If there has been an overload the safety switch may need resetting.
Check to see if the light globe is blown.
Try the appliance in a different power point.
