A typical switch doesn't have a Common screw in the strictest sense, it just has two screws which are each side of the switch. You probably have a a 3-way switch. If you are hooking up a 3-way switch as a normal switch, then connect the Black (Hot) wire to the common and the load to the side of the switch that makes UP the on direction and DOWN is off and doesn't get connected.
You can determine for sure if you have a 3-way switch because the word ON and OFF don't appear on the toggle.

What is the wiring diagram for a light switch in Australia or New Zealand?
In Australia we use 1.5mm2 TPS cable for lighting circuits. The colours for fixed wiring are red - active, black- neutral and green/yellow for earth, also white is used for switch wires. All luminaires and lighting points must have an earth at their location. The process for a simple lighting circuit for looping at the switch method (feed starts at the switch) - one switch and one light point is:The feed (active) goes to the common point on the rocker switch and the neutral goes to the loop terminal on the rocker switch. The earth is connected to a two screw connector separate from the switch. A switch wire is then connected from terminal 1 of the rocker switch to one of the main terminals (these are the terminals across which the lamp terminals are connected) on the batten holder ( this is the fitting which holds the lamp). The other main terminal on the batten holder is connected to the loop terminal on the rocker switch with the neutral. The earth conductor is connected from the two screw terminal at the switch position to the earth terminal in the batten holder.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can you get electrocuted if the switch is off but the breaker is on?
Yes you can. The proper wiring of a switch is to bring the hot wire to the top of the switch terminal and connect the load to the bottom of the switch. When the breaker is turned off it disconnects the voltage from the top of the switch and the switch is then safe to work on. By not turning the breaker off, the voltage is present at the top of the switch which could subject you to a nasty shock if you come into contact with it.

You need two 3-way switches. To see a diagram use your favorite search engine and search for 3-way switch wiring. Each switch has a common connection point and two other terminals. Basically connect the "other" terminal on 1 switch to either "other" terminal on the second switch and then do it again for the remaining "other" terminal. Then connect the common on one switch to the fixture and the common on the remaining switch to supply voltage. Tie neutral and ground for fixture and supply to the white and bare wires respectively.
