I think most Australians who follow the news are well aware of the case. There seems to be some debate as to whether the AFP acted improperly, by making contact with the Indonesian police, as they were aware that if caught they could receive the death penalty, which the Australian government is against.
In my mind it just seems like the police carried out their jobs. What else should they have done? Was it wrong for the AFP to contact the Indonesian police? Should the Indonesian police just let them travel on to Australia even though they were already aware a crime had been committed?
If no contact was made with the Indonesian police, and they waited for the Bali 9 to return to Australia, then the ring leaders could have walked away free as they weren't carrying any drugs.
There is an article here for example which tells the story:

There is a legal perspective here:

Even if the AFP did not violate any legal obligation in providing information to the INP with the knowledge that such information could result in Australians being subjected to the death penalty, it is the author's view that such actions constitute manifestly immoral behavior.
