The History of ‘The Percy Isles, Past and Present’ encapsulates Australian European pioneering history up until the present day, on the Ha Island. It also includes what little is recorded of the Darumbal people, that regularly visited and used the Island for its resources, until 1854, when they encountered European explorers.

The Land Facts: In 2011, the Middle Percy Island Leasehold changed due to political reasons from the Lands Act to the Nature Conservation Act Section 34. Changes included designating 83% of the previous land holding to national park status leaving 316Ha as the Percy Island Conservation Park for residents to manage and protect the Island infrastructure from vandals and to ensure ongoing maintenance of the unique Cultural Heritage and Nature Conservation values of the Island.

The introduced animals are Eastern Grey Kangaroos, Red-Necked Wallabies, Wallaroos and a few Rusa Deer. The Cane Toads were introduced by the Whites with advice from DPI apparently to control the vegetable garden pests. The Whites built a fence about their garden, but the toads escaped and are now all over the Island using the seasonal creeks to breed. Green Tree Frogs were also introduced to control mosquito larvae in rainwater tanks and have become established.
