Holt purchased Laycock's entire estate on the peninsula in 1861 for A£3,275. Holt, originally from Yorkshire, sailed into Sydney sometime in 1842. He made his fortune during the gold rushes of the early 1850s. Holt moved to Sutherland and further increased the size of his property to approximately . He erected several mansions, ran his ‘Sutherland Estate’ in the English manner, and travelled into Sydney to manage his business affairs. In 1868, Holt's land was still mostly uncleared virgin bushland. After Holt had cleared most of the timber, he began to plant grass seeds imported from Germany. The Sutherland Estate was divided into eleven portions. It was then divided into 60 smaller paddocks using Brushwood fencing. The fence posts used to divide these lots can still be found in Towra Point, which is also part of the Kurnell Peninsula.
