Overview

Spilsby Island Lot 21

For Sale on Spilsby Island Lot 21 (Beachfront). Spilsby Island is located approximately 17 nautical miles east of Port Lincoln within the lower reaches of the Spencer Gulf. It is one of a group of 17 offshore islands known as the Sir Joseph Banks Group. Spilsby Island is the only privately owned island among these, with the remaining 16 designated as national parks. Historically, Spilsby Island was used for sheep grazing during the early settlement days of the lower Eyre Peninsula. Today, a portion of the island has been subdivided into 41 allotments, all facing north on the northern side of the island. Each lot owner holds an equal 41st share in the entire island, which spans 356.7 hectares, including the old farmhouse (The Hilton) and adjacent sheds that store the island's equipment.

Access to Spilsby Island is typically a one-hour boat ride from Port Lincoln, and there is a small airstrip on the island, allowing for a ten-minute flight from Port Lincoln Airport. The Sir Joseph Banks Group is renowned for its pristine environment, excellent fishing opportunities, and various outdoor leisure activities. The island also features a well-known right-hand surf break, celebrated for its world-class reputation. Currently, there are approximately 12 established dwellings on different lots.

This property is ideal for someone seeking a retreat in nature, offering a pristine marine environment and abundant wildlife. Lot 21 encompasses 3,756 square meters of prime beachfront real estate, ready for the establishment of a dwelling with no clearing required, and a septic tank is already installed. All owners have access to The Hilton for a fee of $10 per night per person, which must be pre-booked. The Hilton is solar-powered and features four bedrooms with king and queen-sized beds, two bathrooms, and is in good working order. Additionally, there is a two-door Suzuki vehicle available for a one-time payment of $70, along with two front-end loaders to assist with clearing, leveling, and transporting building materials using a purpose-built amphibious trailer barge capable of loading about 2.5 tons of material from any vessel equipped with proper lifting gear.

As an owner, there is an annual Management Association fee of $400, which is managed by a dedicated group of owners overseeing the general upkeep of the infrastructure. Notably, there are no council rates applicable, as Spilsby Island is situated outside of council boundaries. This unique piece of real estate offers a slice of paradise in a secluded, peaceful setting, away from the distractions of modern life.
