Over the years Bennelong has changed into a marginal seat for two reasons. Firstly, the electoral boundary of Bennelong has been changed many times, where it has moved west into Labor voting areas. Rich suburbs like Lane Cove and Hunters Hill in the east are no longer included. The division now includes Eastwood, Epping, Carlingford and working class Ermington in the north and west. Secondly, the type of people living in the division has changed. Since the early 1990s, there has been an increase in migrants from China, Hong Kong, South Korea and India. These are wealthy and conservative people who would support the Liberal Party, but they have not like the Liberal policies on immigration and multiculturalism.
