Look for operators around Terrigal →New South Wales
The Central Coast's headline is the ex-HMAS Adelaide, a 138 m frigate scuttled off Avoca in 2011 that is now one of the busiest wreck dives in the country. Around it are the reefs and caves of Terrigal Haven, Foggy's Cave and the Skillion, the shore dive at Terrigal, and the grey nurse gutters at the Pinnacles off Bangalley Head.

Choose the named outing that interests you first. Compare its recorded place and access with your accommodation plans, then obtain the actual meeting address and schedule from the provider. The site links show the underlying depth, location confidence and source notes. Similar town names or map positions do not establish that two outings can be combined in a day.
A closer look at Central Coast
Our Central Coast directory currently includes 44 published site records. The largest recorded category is reef (16 records). Use the mix below to decide what you would like to read about first.

Start with Foggy's Cave, Lion Island (Broken Bay), Inner Bommies (Norah Head). These are examples from different recorded categories, not a recommended route or a list of the best sites. Open each record for its sources, map and review notes.

A dot shows a recorded maximum. A line joins the recorded minimum and maximum when both are available. These are site descriptions, not target depths or certification limits.
The table above contains the same depth values. Depth alone cannot establish suitability, and records may require correction. Source: the linked site records.
Start with one local base and explore from there. A region can contain several different shore and boat options, so the useful comparison is the whole outing: access, support, equipment collection and the time you have.
For a shore outing, ask about the meeting place, equipment collection, facilities and the actual entry arrangements. For a boat booking, include boarding, return times and what you bring aboard. Neither access label tells you that a site is suitable for you. Share your recent experience and ask about the route the provider proposes for that particular day.
You might be drawn to a wreck record, a rocky reef or a marine-life photograph. Use that interest to start a conversation about the environment and support involved. A wildlife highlight is a reason to look more closely, not a sighting promise. Likewise, seeing a cave or wreck feature in a description does not establish that entering it is part of an appropriate outing.
Work out where you collect and return hire equipment, where the group meets and how much of the day the activity occupies. Plan meals, accommodation and any non-diving company around those details. If the preferred outing changes, ask which alternatives would still suit the group. A short list with clear arrangements is easier to use than a long list of famous sites.

THE LOCAL PLANNING BRIEF
There are 44 published site records in Central Coast. The recorded categories include reef (16), wreck (10), shore/rock platform (6), wall (6). These categories reflect the database; they are not a ranking, a conditions report or an assessment of your suitability.
Use the Central Coast site cards to compare recorded access and depth, then open the individual pages for the map accuracy and source notes. Sites grouped in a region are not necessarily close enough to combine in one day.
Research operators in New South Wales →Save the answers with the contact name and date. Separate confirmed arrangements from items still waiting for a reply.
Record your trip questions →Begin with the individual site and its source notes, then discuss the proposed trip with a local provider. The 44 published records are research options, not a list of trips available today. Match the plan to your training, recent experience and the operator’s current requirements.
Choose dates with a provider who runs the activity you want, then discuss seasonal patterns, recent conditions and alternative itineraries. A generic best-month claim cannot establish the conditions at your exact site or guarantee a wildlife encounter.
No. Recorded and approximate map positions support orientation only. Confirm the exact access, permissions, meeting point and route with the responsible local provider or manager.
