Dux Anchorage is a private waterfront retreat on South Stradbroke Island, Queensland, operated by the Southport Yacht Club for the exclusive use of its Gold-tier members and equivalents.

Accessible only by water, the property sits on approximately two acres along the island's shoreline and serves as a popular destination for both day trips and overnight stays.

On-site facilities include a small clubhouse, picnic and camping grounds, barbecues, modern amenities, a floating pontoon, and a resident caretaker.

South Stradbroke Island itself borders the calm waters of the Gold Coast Broadwater on one side and surf beaches on the other, with largely untouched native bushland in between.
