expired Canon EF 50mm F1.8II Lens $99 Pickup at DSE (Limited locations)
This seems to be the cheapest price around for an "Australian" stock** If you are looking for a good beginners prime lens, you should definitely take a look at this lens.
It's a handy lens if you are purchasing the 1100D for $328 at HN :)
They seem to have limited quantities in QLD, not sure about other states.
**(meaning that Canon will service it if you have any issues during your Warranty period)
