Jones Bay - Poor Knights Islands
Jones Bay, nestled on the Poor Knights, feels like a sheltered kindergarten for the resident fish. It’s a shallow spot, topping out at seven metres, making it perfect for newer divers or those looking for a long, relaxed safety stop. We’ve spent plenty of time here just watching juvenile snapper and demoiselles dart through the kelp, occasionally spotting an eagle ray glide past the entrance. The calm, clear conditions usually make for easy viewing, though a good torch helps peek into the darker crevices. It’s a gentle introduction to the Poor Knights vibe.
