What do you need to charge a phone in Australia?

In Australia, the power plugs and sockets are of type I. The standard voltage is 230 V and the standard frequency is 50 Hz. So the type of electrical charger required in Australia is the AS/NZS 3112 plug: a three-pin, flat-pronged with an earthed (round).

Some devices with two-pin power cord plugs can use type I sockets for power by using a Type I – I/E Plug Adapter or Type I - E/F Europlug, depending on where the device orginates from.
