Australia’s Diet Trajectory 2030: Alarming Fruit Drop and Junk Food Climb

Imagine opening the fridge in 2030 and finding less fruit, unchanged vegetables, and more chips, soft drinks and takeaway than ever. That dystopian diet isn’t fiction—it is what recent research from CSIRO suggests is quietly becoming Australia’s reality. Without intervention, the nation is heading further away from its health targets, and the cost—in wellbeing, economic burden, disease—is mounting. TMFS believes that when data points to danger, leadership must respond before the warning becomes crisis.

The numbers are stark. A modelling study published in the Australian and New Zealand Journal of Public Health used data from more than 275,000 Australian adults surveyed between 2015 and 2023 to project diet trends out to 2030. Key findings: fruit intake is expected to fall by about 9.7 percent. Discretionary food consumption—those ultra-processed, high-salt, high-sugar, high-fat foods—is projected to surge by roughly 18.3 percent. Vegetable consumption, meanwhile, is likely to stay nearly static, remaining well below the national target of five serves per day. PubMed+2CSIRO+2

Age and sex matter. Australians over 71 may face a 14.7 percent drop in fruit consumption by 2030. Women are predicted to see a sharper decline than men in fruit intake, and also a steeper rise in junk food consumption. Young adults aged 18-30 show modest hope—they are projected to slightly increase fruit and vegetable consumption—but that gain is overshadowed by high intake of discretionary food. Across the board, we are moving away, not toward, national health objectives. PubMed+2CSIRO+2

Why does this matter beyond statistics? Because diet shapes disease. Poor dietary quality is a leading contributor to obesity, type 2 diabetes, heart disease and many cancers. When fruit and vegetables decline and junk food climbs, risk factors accumulate: nutritional deficits, inflammation, excess caloric intake, weight gain, and higher healthcare costs. For individuals and communities, especially those with low income or remote access to fresh produce, the consequences are profound. For Australia’s health system, this trend threatens to erode gains in preventive health.

The modelling compares these trajectories against Australia’s National Preventive Health Strategy targets: two serves of fruit per day, five serves of vegetables, discretionary foods making up less than 20 percent of total energy intake. Under current trends, the 2030 goals are likely to be missed by a wide margin. CSIRO+2ABC+2

Several structural forces appear to drive this negative trajectory. Rising cost of living and inflation has made fresh produce harder to afford. Convenience, time pressures and marketing of processed foods tilt behaviour toward quick, cheap, less healthy options. Also, awareness of nutritional recommendations remains superficial for many, and social supports for healthier eating—access to affordable markets, encouragement, and policy incentives—are uneven.

Yet this is not a foregone conclusion. If leadership and policy align, course correction is possible. Interventions that have shown promise include pricing strategies (subsidies for fruit and vegetables, taxes or levies on sugary drinks and ultra-processed foods), public education campaigns that clarify what a healthy diet looks like, stronger regulation of food marketing especially toward children, and investment in supply chains that reduce costs for fresh produce in remote or disadvantaged regions.

The takeaway is both urgent and hopeful. Australia is at a tipping point. The path toward 2030 need not be one of declining diet quality and rising disease burden. But avoiding that descent requires decisive action now—by governments, communities, businesses, and individuals.

TMFS holds that leadership in public health is rooted in preventive insight, evidence-driven policy, and equitable access. We urge policymakers to act on what the CSIRO modelling reveals. Strengthen food policy, make healthy produce more affordable and available, regulate marketing of discretionary foods, and support public awareness of what constitutes a healthy diet.

For every Australian, the choices matter—what we eat every day is a signal of health and collective responsibility. Let us reverse the trend, not wait until the implications become too visible—and costly—to ignore.
