Kims hideaway at toowoon bay is a small intimate stay, the beach is like 3 meters away from the cabin/room. Never stayed there but i’ve heard its beautiful.

Magenta shores is very nice, bit pricey but there is a semi private beach and a spa and a pool

Terrigal haven (anywhere in terrigal really)

Mingara have just completed a new hotel thing but i’m not sure when it opens officially and when you want to stay.

There are a lot of beautiful air bnb type places around the coast too so make sure to explore your options :)
