Burke dove with several dive operations on Cayman Brac and became a co-owner of Brae Aquatics. As a pioneer of diving in the Brae he has explored and named more than half of the dive sites on Cayman Brae and many on Little Cayman. He was also involved with sinking two wrecks - the Mariner and the Kissimmee - in Cayman Brae. Burke was a popular dive master and was well liked by his regular customers who still stop by to visit. He was, and still is, a good ambassador for the Sister Islands, attending many DEMA trade shows and assisting with Nikonos Shootout competitions, visiting handicapped diving groups such as Moray Wheels and helping visiting marine biologists from the University of Maryland with their research.
