Food prices directly impact on the ability of individuals to follow a healthy diet, particularly those from a low socioeconomic background. The Illawarra Healthy Food Basket (IHFB) was designed to monitor the cost of a basket of healthy food items. The present study has updated results collected regularly since 2000. The IHFB consists of 57 food items chosen to meet the nutritional needs of a reference family of five. The costing was conducted at a supermarket, greengrocer and butcher in five suburbs in the Illawarra region in September 2009. Comparison was made to social welfare payments obtained from Centerlink and Average Weekly Earnings (AWE) data from the Australian Bureau of Statistics. The average cost of the IHFB in 2009 was $278.79, $77.33 (38.4%) higher than the baseline in 2000. The increase since 2007 ($36.30; 15%) was the highest in any two year period since 2000, with the largest increase being for fruit. The total cost was 30.2 % of AWE and 30% of the total social welfare payments, similar to levels reported previously. Despite significant increases in the price of the IHFB, the cost of the basket has remained relatively constant compared to average weekly earnings and social welfare payments. This suggests that the affordability of healthy eating in the Illawarra has not changed substantially in recent years.
