Thanks for paying for my advice. But there's more:
Even if you didn't use the printer with it powered through a surge protector, you are still entitled to free (or very nearly) service or replacement (depending upon the exact terms for this exact model), *if* it is still less than one calendar year since you bought the printer new - Canon (and most other printer manufacturers) cover their printers under a one-year warranty.
If it is not covered (make sure you didn't buy Extended [Warranty] Coverage, which is for longer than one year, when you bought it), then you would be well advised to get an estimate on repair costs, before committing to having it repaired - repair costs might well be more than replacement cost.

If you need to contact a Canon Service Center for your model in your area, call Canon Australia about that, asking where nearby service centers for your model #, the MP600, are. Or you could try finding your way through the not-very-easy-to-use Service Locator:http://www.canon.com.au/en-AU/Support-Services/Dealer-Service-Locator
Lastly, if you decide to replace it rather than repair it or have it repaired, you would be well advised to recycle it rather than throwing it in the trash. Canon USA has recycling... I'm not sure Canon Aus. does, you could ask them if you call them, also... or you could offer it for free on your local craigslist.com or freecycle.org (if freecycle has an Aus. branch, I'm not quite sure) - some parts at least, in it, will be reusable by some small business or hobbyist.
