This was the start of marathon surgery and hope of a new and independent life for conjoined twins Krishna and Trishna.

The girls, whose heads were joined, were brought to Australia from Bangladesh where their mother put them in an orphanage soon after birth.

It's taken a team of 16 surgeons and nurses an intense 25 hours to separate them.

The head of Melbourne's Royal Children's Hospital says it's all gone well so far.

[Leo Donnan, Royal Children's Hospital, Melbourne]:
"We'd like to announce that there has been successful separation of the twins. At 11 o'clock this morning the teams managed to separate the brains and they are both very well. Now we have the long task of the reconstruction surgery which will go on for many hours. We can't predict how long it will take. As you know, any predictions we've made so far haven't exactly gone to course but what I can say is everything we've done has gone successfully and we've been very happy with the way it's been going for these girls."

Despite the success of the surgery nobody is celebrating just yet.

These are early days and complications could still set in.

Hospital staff who've got to know the girls during the two years they've spent planning surgery say just seeing them as separate human beings was an amazing moment in itself.
