These studies you have quoted seem to be very old. I recently had a look at the Lyme disease symptoms report a PDF compiled in 2006 from
on page 2 regarding geographical distribution.
it states that :
“Lyme disease has been reported from five continents—Africa, Asia, Australia, Europe, and North America. ...In North America, Lyme disease occurs in both the United States and Canada. Within the United States, it is now the most commonly reported tick-transmitted infection...The disease is endemic along the East Coast from Maryland to Massachusetts, in the upper Midwest in Minnesota and Wisconsin, and on the Pacific coast in California and Oregon. Increasing numbers of cases have also been reported from mid-Atlantic, southeastern, midwestern, and southcentral states. But the illness remains most common in the states from which it was originally reported...New York, New Jersey, Pennsylvania, Connecticut, Massachusetts, Rhode Island, Wisconsin, and Minnesota. ...Lyme disease is both widespread and common in Europe where thousands of cases are estimated to occur each year. The disease is most common in Austria, Germany, France, Sweden, and Switzerland. But is also occurs in the three other Scandinavian countries, Belgium, Czechoslovakia, Hungary, Italy, the Netherlands, Romania, Spain, the United Kingdom, the USSR, and Yugoslavia.”

“Patients with the disease have also been found in China, Japan, and Australia.”

“B. burgdoferi-infected ticks may be transported from Lyme-endemic areas into nonendemic areas, which may establish new Lyme-endemic foci. Infected I. ricinus complex ticks (including I. scapularis) and infected I. uriae have been found on migratory birds and along migratory “flyways”; they may be transported into new areas by these birds as they travel between endemic and nonendemic areas, including counties, states, countries, continents, and even hemispheres.”

so clearly it exists in Australia whether or not mainstream doctors wish to acknowledge it is a different matter. I would guess it's something they try and blanket to create more $$ for the sickness industry.
