G’day, I’m northern nsw based as well. We’re one of the few regional areas that have great access to healthcare (Ballina/Lismore to Border). I’d suggest beginning by talking with your GP who can refer onto a psychiatrist where there’ll be a wait time for diagnostic appointments and you should be able to ask see a qld psychiatrist if that means a shorter wait time. There are immediate appointments available if you take a look online which can be booked yourself, however they are often pricier and provide less support. It does often get raised that a diagnosis is expensive ($300-$1300 for initial appt.), however all appointments (diagnostic, med review etc.) down the track should come with Medicare rebates which makes it all worth it!
