How much does a marina berth cost in Australia?

We do not publish berth prices yet, and we would rather say so than estimate. Australian marinas very rarely publish tariffs online, and a made-up figure would be worse than none.

What we can tell you is what actually drives the number:

Length, not size. Almost every marina charges per metre of vessel length, usually annually or monthly. A berth quoted at a per-metre rate multiplies fast, and many marinas charge on the berth length rather than your boat's, so a 12m boat in a 14m berth is billed for 14m.

Region, heavily. Sydney Harbour is the most expensive water in the country; regional Queensland and Tasmania are materially cheaper for the same length. Moving 40km can change the annual figure more than moving up a boat size.

Wet berth versus dry stack versus swing mooring. Dry stack is typically cheaper for trailerable powerboats and includes launching. A swing mooring is cheaper again and includes nothing.

The extras that are not in the headline rate. Electricity metering, liveaboard surcharges where living aboard is permitted, key or fob deposits, insurance requirements, and hardstand day rates when you haul out.

The one reliable way to compare is to ask two or three marinas in the same region for a written quote for your exact length, and to ask specifically what is excluded.
