Shark attacks are part of the reality of enjoying the lure of the ocean. In Australia, as in the U.S., this is more common on the West Coast. A fair number of approaches have been tried to keep swimmers safe. On my first trip to Australia, I swam in a shark cage near Port Hedland, which did the trick but was fairly confining. Efforts to achieve safety have continued. After additional decades of effort, a new option was developed and tested in Western Australia (WA). The good news is, the Eco Shark Barrier works well and the company that invented it is now the world’s leading purveyor of systems that keep both swimmers and marine life safe.
