Yay Loulabelle!!!!

Give 'em a call. I don't think there are any laws in place- nothing has currently really changed with regards to home birth with an independent midwife. Just don't expect your MW to be able to bill to medicare. And if you possibly want to birth at home outside of the box (twins, breech etc) you'll need to find a midwife who's happy to have an "oopsie" and don't have ANY scans (evidence of twins etc).
Mine still bulk bills Medicare for pre and post natal visits. I don't think they were ever able to do that for the birth (my PHI does though). New laws changed possible access to medical indemnity for independently practising m/ws and possibly the link to Medicare, but I don't know if that's in place as I think temp measures are in place for current practicing m/ws. But I'm no expert!

My GP and m/w can both refer for scans, but were you saying if you don't want any scans?
