The Indonesian national police forensic team has quickly been able to determine the number of bombs involved. What we're working with them on now is the actual make-up of the bomb. They're quite a different bomb to the ones we've seen been used before.

I can confirm to you that a 16-year-old male from Western Australia and a 48-year-old woman from NSW have been killed in the bombing in Bali overnight,

If he is confirmed as being the person who has died in this operation ... it will make a big dent in the operations of the radical terrorist groups in Indonesia.

But how well organized they are, what their capacity is to actually mount any operation remains to be seen,

In some places they will use a cleric who has a good reputation with the community and who will be respected and listened to by the people in custody.

They have three heads that they're examining and that's a typical outcome from a suicide bomber, but that's not yet confirmed and that will require further analysis as the evening progresses,

It's important that we give these people a fair opportunity to prepare their defense before the court rather than run their trial in the media.

All of us are very surprised at some of the things that have happened in the last, say, 12 months. To find, for example, in the U.K. that we have got people who are homegrown terrorists is a big move from where we were, say, four years ago or three years ago.

This is not something that we can do as Australian Federal Police by ourselves,
