that less than 10 per cent (around 160 people) of residents aged over 65 had lived in the area for less than 5 years, leading to a lack of specific aged-care facilities. The same source claimed "The government in the south-east area of the state, consisting of three local councils, amounted to a single administration. In consequence, many residents of Victoria used to look across the border to Mount Gambier as their centre. Consequently, during the 1970s many elderly locals relocated to Victor Harbor and Moonta, both rural areas but with more resources available to cope with an ageing population".
