Sadly enough, the medical profession and the Australian Government won't recognise that Lyme disease exists in Australia and won't treat for it even is you get the testing done in the US to confirm it. This is odd considering just how many Australians travel to Lyme areas for skiing and holidaying, let alone the rising evidence here that it does indeed exist.
What they do at present is to diagnose you as having motor neurone disease and tell you to put you affairs in order and go home and get ready to die.
Australia normally has a pretty good level of medical care and access but in this disease, there is no path for help apart from one or two doctors that are seen as radical and unreliable/untrustworthy for their identification and treatment of patients presenting with Lyme. It's a real battle here that I am watching happen to a member of my family and it fills me with despair that something that is so treatable is apparently a political hot potato that nobody wants to touch.
Yes, it's rare for the reasons that Lymestser said - and said well.
