Less than 100 years after Cook's landing, most of the original vegetation had been cleared and burnt, larger trees had been ring barked or simply cut down. Thomas Holt who was the first owner of the area (and who also owned most of what is today the Sutherland Shire) planned to use the dunes for farming sheep, this industry failed more or less. To promote grass growth he destroyed as many of the oldest trees as was viable and to his dismay all that regrew was dense impenetrable thorny scrub. By 1868 the forests of blackbutt and ironbark were cut down for houses and bridge construction whilst the remaining vegetation was cleared for grazing. The first land grant was issued in 1815 when a whaler and merchant by the name of James Birnie, was given of land and of saltwater marshes on the Kurnell Peninsula. The grant included Captain Cook's landing place. He called it ‘Alpha Farm’, and built himself a cottage there. In 1801 John Connell, an ironmonger, arrived in Sydney as a free settler. In 1821 Connell was granted at Quibray Bay next to Birnie's grant. When James Birnie was declared insane in 1828 John Connell gained possession of his property. John Connell now had full ownership of the Kurnell Peninsula. Connell erected a new house, which he named ‘Alpha House,’ built on the foundations of Birnie's original cottage.
