In this third and final installment of the School Ship Tobermory adventure series, the same loveable cast and crew are back, sailing to new locales in Australia with adventures that don't disappoint.

Ben and Fee MacTavish and the rest of the school ship Tobermory crew head to Australia to take part in a tall ships race. But after a good start, the Tobermory unexpectedly changes course to rescue a local boy, Will, who is stranded on the rocks. When the ship's dog, Henry, disappears, Will helps Ben, Fee, and their friends find him, but as the trail leads them deeper into the Outback, they begin to realize that a missing dog is the least of their problems. Join the crew aboard the Tobermory as they set sail from their home base in Mull to the Southern Hemisphere on an adventure they won't soon forget.
