Hi, if you give them a call I am sure they will give you directions.
The turn off is near the town of Aratula
you take the Lake Moogerah Rd turn off to the left. There is another road in from the south west but not sure what that is called. The retreat is at 2055 Lake Moogerah Rd. If you are familiar with rural property numbers you will know that is approximately 20 klm from the closest major intersection, so keep your eyes on the property signs as you get closer. They have an ad in TAN and they may also be in the phone book.
