Well, thats just what SydneyIVF's website claims.
HunterIVF stats given to me verbally were 50% with IVF or aprx15% with AIH (IUI), however SIVF's website stats say 50% with IVF only for under 25's.

SIVF website says IUI = $1307.50 initial costs, or $168.80 after 80% Medicare SafetyNet (if eligible).

HunterIVF says IUI = $883.50 for non-medicare people (eg: visitors) or $519.40 for medicare people - $99.40 medicare = $420.
If eligible for 80% SafetyNet = $84.

Half the price.
