This report examines the issue of food waste in Australia, highlighting its significance and the need for effective marketing strategies to address it. The paper begins by outlining the background of food waste in Australia, emphasizing the substantial amount of food wasted annually and its impact. It then delves into the major causes of food waste, including reliance on take-away food, poor grocery planning, and lack of food management, and the specific demographic most involved in wasting food. The report analyzes a previous marketing strategy, the Foodwise campaign, identifying its shortcomings, such as lack of consistent social media engagement. A new marketing strategy is proposed, emphasizing the 4Ps (Product, Place, Price, Promotion), 5Cs (Customer, Company, Context, Collaborators, Competitors), and STP (Segmentation, Targeting, Positioning) of marketing. The report recommends that the new campaign focuses on consistent social media presence, targeting youth, and potentially partnering with large restaurant chains to increase awareness and achieve sustainable consumption goals. The report concludes by emphasizing the importance of integrated marketing, particularly social media, to reach the target audience effectively.
