One of the main differences when it comes to the United Kingdom and Australia is that delivery care is under federal authority, so making change happen is a little more nimble than in Canada, where care is delivered by jurisdiction.
What the U.K. did was it developed programs to enhance access to psychological therapies. They trained many health care providers. The programs are static. They collect data on over 90% of every visit. The programs are evaluated. Often the psychologists take the role in terms of evaluation, but the delivery is by a range of health providers who work within these facilities, and they have been able to make a huge difference. Tens of thousands of people have gone off disability payments. Recovery rates are about 60% for those living without symptoms in recovery.
What Australia has done, conversely, is more of a fee-for-service model. They have a program called enhancing access to family doctors, psychiatrists, and psychologists, and some other specially trained providers as well. They will fund up to six sessions of services, renewable three times, of services on the referral of a family physician for mental health care, but that may have changed.
