Hello Linda,
Although they may be your business opposition, have you tried writing to the owners of other clinics in your and surrounding areas?
It may be that other clinic owners / managers would be interested in taking on a going concern to expand their own businesses.
I do not know if some of the franchise businesses operate in Tasmania, but there could be a possibility that a going concern (your clinic) may interest them eg in running the business for you or purchasing. Just a thought.
