Wellbutrin in Australia?

Any one know why Wellbutrin is not sold in Australia?
We have Zyban but the docs will prescribe it for only 3months since its a smoking cessation aid.
I am on my 3rd week on Zyban and the results are great, I have quit smoking and feeling so much better than before.
I have tried most of the ssri on the market and the side effects are terrible.
I really want to use Wellbutrin for my depression!

Don't quote me but after doing some research, I believe the reason is that they do a cost-benefit analysis and Bupropion is one of the more expensive antidepressants out there. It's indicated as a smoking cessation aid probably due to the fact that people will only be on it temporarily.

Thank you for the information, guess my doc wont be happy to keep me on it.
