 Ocean Reef was created at the 2007 redistribution out of most of the Mindarie electorate and parts of Joondalup and Hillarys.Its creation reflected both the growth of the City of Wanneroo region which now required three full electorates (Wanneroo, Mindarie and Girrawheen), and the increase in the number of metropolitan seats in accordance with the new one vote one value legislation.Ocean Reef was a notional Labor seat upon its creation, but was one of a number of marginal seats that fell to the Liberal Party at the 2008 election.
