Thanks for the information re Anti-D alternative... I am having trouble finding out information about the alternative and where it is available.

has anyone else had any luck with this?

I contacted the TGA who said that the only anti-d shots on the medical register are the blood plasma types. I've sent an email to the distributor in the US, so I'll keep you posted, but if you know of anything else, I would really appreciate your help!

Many thanks
