Frequently Asked Questions
Quick answers sourced from research and local operating patterns.
Grey nurse sharks can be seen around Fish Rock year-round, but local operators commonly report the highest numbers from May through December. If sharks are your main goal, aim for June to September for cooler water (often 18°C to 22°C) and strong aggregation behavior in gutters and near the cave entrances. October to December can add warmer water and better natural light at the shallow entrance. Because offshore conditions can cancel boats, build a 3 to 5 day window so you can wait for the best sea state.
Hammerhead sightings are most often reported in the warmer part of the year, with the classic window running from October to January. They are usually seen on deeper, current-influenced sites around Fish Rock rather than inside the cave itself. Plan for blue-water conditions, variable current, and dives that may sit in the 20 m to 30 m range depending on the site. If you are traveling specifically for hammerheads, book multiple dive days and stay flexible because sightings can be weather- and current-dependent.
Fish Rock Cave is an overhead environment with two entrances (about 12 m and 24 m) and sections that narrow. You do not need full cave certification for the common guided routes, but you should be an experienced Advanced Open Water diver who is calm in overhead spaces, comfortable with torch use, and able to hold buoyancy without silting. If you are newly certified, focus on open-water sites first and ask the operator whether a progressive plan is possible. Bring a primary and backup torch as standard.
Water temperature around Fish Rock is commonly seasonal. In summer and early autumn you can often expect 22°C to 26°C, while winter and early spring can drop to about 18°C to 22°C. Most divers are comfortable in a 3mm suit in summer, and a 5mm suit in winter. If you run cold, add a hooded vest for longer boat intervals. Snorkelers should also consider a light suit or rashguard for wind chill after swims.
Start with sheltered water and easy exits. Horseshoe Bay is the usual first choice, especially around the protected edges of Horseshoe Bay Reef. Back Creek is a good fallback when surf is up, because it is protected from swell and current. Avoid exposed rock platforms and do not assume rock pools are safe in swell. For any ocean snorkel, go early on calm days, stay inside flagged swimming areas, and snorkel with a buddy. If visibility is poor (under 3 m), switch to a topside plan.
Port Macquarie Airport (PQQ) is the closest flight option for many visitors. From the terminal, the simplest route is to rent a car and drive north on the highway corridor to South West Rocks. Plan on roughly a 80 km drive, with extra time if you stop for supplies in Port Macquarie. If you are arriving late, consider staying overnight in Port Macquarie and driving up in the morning to match dive check-in times. Taxis and private transfers exist, but availability can be limited compared with major cities.
Public transport is possible but less convenient than driving. A common route is to take the train to Kempsey on the NSW North Coast line, then continue by taxi or a pre-booked shuttle to South West Rocks. Some regional buses run between nearby towns, but schedules can be limited, especially on weekends. If your trip is dive-focused, a car or organized transfer helps because dive boats, national park lookouts, and backup plans are spread out. If you are car-free, choose accommodation close to town so you can walk to beaches and food.
Grey nurse sharks are protected, and NSW promotes a Code of Conduct for divers at critical habitat and aggregation sites. Key points include: do not touch, feed, chase, or harass sharks; do not block cave entrances or gutters; keep groups small (no more than 10 divers); and avoid disruptive devices such as scooters or noise makers. Night diving is not allowed at some critical habitat sites. In practice, the best approach is to hold position, keep fins controlled, and let sharks pass naturally. Your operator briefing should reinforce these rules before each dive.
Fish Rock and Green Island are listed as grey nurse shark critical habitat areas with specific fishing notifications. At Fish Rock, line fishing using bait is restricted, and spearfishing is prohibited within 200 m of Fish Rock except for certain pelagic species. These rules are designed to reduce accidental shark hooking and disturbance. If you plan to fish or spearfish, check the current NSW DPI rules before you go, carry the correct NSW Recreational Fishing Fee where required, and be ready to change locations if you encounter grey nurse sharks.
Whale migration along the NSW coast typically runs from May through November, with different peaks as whales move north and then back south. For land-based viewing, Smoky Cape Lighthouse and other headlands in Hat Head National Park are strong vantage points because you are elevated above the waterline. Bring binoculars and plan for early morning sessions when wind is often lower. If you are diving, you may also spot blows and breaches between sites on calm days. Always keep a respectful distance and follow any local viewing guidelines.
