Bay of Fires on my own

I’m heading to the Bay of Fires next week, never been there, and I’m keen to do the so-called iconic walk but not with a group.I get the impression it’s a beach walk with some boulders to get over, is that a fair comment? I would walk from Eddystone lighthouse to Binalong Bay and probably do this as a series of out and back day walks, much as I did the Yuraygir coastal trail a couple of years ago. I have heard there are no water tanks at the campsites so water could be an issue and I thought it best to have my car nearby each night. So the itinerary would be Eddystone to north side Anson Inlet and back, drive around the inlet, inlet south side to the Gardens and back, Gardens to Binalong Bay. I’m finding it hard to get info because all my searches lead to paying walk sites. Apologies if I have failed to find a similar thread on this site.
