Vacation Bible Camp for Lutherans in Ohio when I was growing up was simply not that hard core. Even if the adults had wanted to do an exorcism, I am quite confident that they wouldn't be sure if it was actually a Lutheran thing, and certainly had no idea how to do one, or any inclination to experiment. Our camp counselors were more the guitar playing, long haired, kumbaya singing, finger paint project types. For that matter, neither do the local official Lutheran church authorities:
The Lutheran Church has tried to distance itself from the embarrassing affair, saying that it does not condone practices such as exorcism.
"The Lutheran Church does not endorse or encourage any actions which are abusive or which results in the limitations or freedoms of any individual," Robert Voigt, president of the Lutheran Church in South Australia [said.]
But, this is not the first time Lutherans have done this in Australia:
Joan Vollmer, 49, died in January 1993 after her husband, Ralph Vollmer, and three other members of a breakaway Lutheran sect performed an exorcism at the couple's home in western Victoria.
Maybe it has something to do with Lutherans being so much more of a minority in Australia than they are in Ohio and Michigan, where I usually encountered them. Minority religion status can heighten one's resistance to ourside opinion and increase one's need to vigorously assert one's religious identity.
