Attempting to get auto complete working for my google maps application.

Here is the current code:

HTML

<input type=text class=clearText id=address name=address value= size=20 autocomplete=off>

Javascript

    var input = document.getElementById('address');

    var options = {

        componentRestrictions: {country: 'au'}

    };

    var autocomplete = new google.maps.places.Autocomplete(input, options);

Unfortunately nothing happens when typing an address.

Any ideas?

Thanks in advance.

Edit: I'm actually receiving the following error:

Uncaught TypeError: Cannot read property 'autocomplete' of undefined

Not sure why, the code is placed in my map initialize function.

Edit 2: Fixed. Answer below.
