About this site
The northern tip of Big Brother is a shallow plateau dropping into the vertical reef wall that holds both the Numidia and Aida II wrecks. Divers typically begin here in the blue to scan for grey reef and thresher sharks before drifting down the coral-clad wall. The exposed point catches the prevailing current, concentrating pelagic action.
