Appointments are made online.  Click on any of the book now buttons and you will be taken to the booking calendar. 

You can choose the day and time that suits you.  You will receive an email confirmation of your appointment and you can cancel or reschedule anytime by clicking on the link in the confirmation email.

No you do not need a referral to make an appointment.

Unfortunately no.  Private health generally and Mental Healthy Plans cover practitioners with a Medicare Provider number.  Counsellors are not allocated a provider number. Yep. That sucks!
