Im sorry to hear @Mustang67. it can feel so disappointing when that happens. It can happy for many reasons and hopefully they will let your GP know (if not, and you want to know why, you can always call them back to ask).
Having been both a patient and a secretary with regard to psychiatry before, I reckon most likely is closed books due to too long waiting list (or if winding up practice).
Its possible it could be unable to offer bulk billing spots (but if this was the case, I would expect them to then talk about what the full price is, so that sounds less likely in this case).
I remember working for a bulk billing psychiatrist a decade ago (one of the very few private ones!) And their wait list for new patients was usually 6months+. Even longer for medico-legal assessments.
I hope your GP can refer to another psychiatrist, and hopefully one who will bulkbill you - especially if its just a once-off medication review.
Does your area have any psychiatrist medication advise line? My region has one especially so that GPs dont need to refer a patient who then has to wait 6mths+ for what could be a 10min chat between a psych and a gp!
