Ooooh exciting JBM! Did you make a decision? We are in the same boat, our last embryo is in MIVf and we are in Canberra. We have decided that for us we would prefer to stick with MIVF and fly down for the initial consultation and FET rather than transfer our embryo up here, though there will be some contact with the clinics here for blood tests and ultrasounds etc. I found some info for a clinic here stating it was around $700-900 to transfer an embryo between clinics, but I have no idea if that's standard or not (FWIW their out of pocket costs for a FET were about $700 more than MIVF so maybe this particular clinic is on the dearer side?).

Good luck, let us know what you decide.
