Unless your device's power adapter says "100 - 240 V, 50 - 60 Hz" somewhere on it, you need a voltage converter. All recently released desktop Macs, peripherals like the Time Capsule or Apple TV, and notebook or iPod power adapters should be universal voltage, as are many camera battery chargers..
Keeping this in view, do Apple products need a voltage converter?
Apple products, such as your iPhone, iPad and laptop, are dual voltage, therefore you do not need a converter to use your Apple device anywhere in the world. You can tell if you if your electronic device is dual voltage by looking on the voltage rating on the device.
Also, is my MacBook dual voltage? The MacBook Pro runs on every voltage available in the world, specifically it runs on 100 to 240 volts at 50 or 60 hertz as well as 15 or so volts (DC) from its battery. A plug adaptor is the only thing you will need. It's not just "dual voltage", but universal voltage within the specifications of the power adapter.
Keeping this in consideration, can I plug my MacBook into 220v?
Yes all you need is a plug adapter to convert to the correct plug style. You can either use the world travel set from Apple or by just a plug adapter that the MagSafe will plug into. I concur with the previous poster, it works just fine on 220v as long as you have a converter plug for the electric outlet.
Do I need a voltage converter for my iPhone in Australia?
The US operates on a 110V system, Australia and most other countries run a 220 to 240V system. Some appliances, particularly those used for travel like cameras or hairdryers, can operate on both systems. It should say on the plug or transformer what voltage it can handle. You will definitely need a plug adapter.
