Aussie Bay Campsite is a small, basic DOC campground situated on the shore of Queen Charlotte Sound/Tōtaranui in the Marlborough region of New Zealand's South Island.

Accessible via Queen Charlotte Drive, the site offers a tranquil seaside setting with six unpowered tent sites. Facilities are minimal — toilets only — making it a quieter, more low-key alternative to the nearby Momorangi Bay campground.

The location suits kayaking, swimming, and exploring the Queen Charlotte Track, which offers both walking and mountain biking. Access is via a steep driveway with tight turning, and the site accommodates motorhomes up to seven metres in length.

Fires are not permitted. The campsite is managed by the Department of Conservation.
