Aboriginal people in the Parramatta area began moving to new areas soon after the arrival of the colonists at Port Jackson. A military post was established at Parramatta in November 1788 which resulted in a group of Burramattagal people moving into Wallumedegal area at Kissing Point.Smith, p. 12 The impact of illness on local people in the immediate years after arrival has been considered to be due to smallpox. Increasingly this belief is questioned as to the feasibility of such an illness being carried for 15 months at sea.Campbell, pp. 39–50
