Written & Photographed by Troy Mayne 

Meet Casey, Shelley and Wally in an adventure photographed on Australia’s Great Barrier Reef.

​

When Wally takes Casey’s lunchbox and hides it in the schoolyard, the two turtles must find it before the school bell rings.

​

Their search becomes a reef adventure filled with friendship, humour and consequences—and introduces the characters who would eventually become Wally’s Reef Gang.

​

Every marine animal in Sorry Wally is shown using genuine underwater photography.

​

Real animals. Real photographs. A real reef adventure.
