Australian consumer confidence has deteriorated further in June, with households across the country expressing growing concerns about rising living costs, higher borrowing expenses and the nation's economic outlook.

The latest Westpac-Melbourne Institute Consumer Sentiment Index fell to 80.6 points in June, down 2.9 per cent from the previous month. A reading below 100 indicates that pessimists outnumber optimists, with the latest result placing sentiment among the weakest recorded in the survey's 50-year history.

Westpac's head of Australian macro-forecasting, Matthew Hassan, said the findings highlighted the mounting pressure many households continue to experience.

"At 80.6, the latest monthly index read is back amongst the weakest seen in the fifty-year history of the survey," Hassan said.

Several factors have contributed to the decline in confidence, including persistent cost-of-living pressures, elevated interest rates and increasing fuel prices. Many Australians remain concerned about their ability to manage household budgets as essential expenses continue to consume a larger share of family incomes.

The survey showed that expectations surrounding personal finances weakened significantly during June, reflecting ongoing uncertainty about future economic conditions. Households also became less optimistic about Australia's broader economic prospects over the next 12 months.

Confidence in the housing market also softened, with fewer consumers expecting strong growth in property values. Analysts believe changing market conditions and recent policy discussions surrounding housing and taxation may be influencing buyer sentiment.

Although there was a slight improvement in consumers' willingness to purchase major household items, the measure remained well below its long-term average, suggesting Australians continue to prioritise essential spending over discretionary purchases.

Economists warn that prolonged weakness in consumer confidence could weigh on retail spending and broader economic activity in the months ahead. Household consumption plays a vital role in Australia's economy, and cautious spending habits often reflect deeper concerns about employment security and financial wellbeing.

The latest figures arrive as policymakers and economists closely monitor inflation trends and the impact of higher interest rates on Australian households. While inflationary pressures have eased from their peak, many families are yet to feel meaningful relief in day-to-day expenses.

For businesses, the decline in confidence presents additional challenges, particularly for sectors reliant on discretionary consumer spending. Retailers, hospitality operators and service providers may continue to face subdued demand if households remain focused on managing financial pressures.

Despite the gloomy outlook, economists note that improvements in inflation outcomes and greater certainty around interest rates could eventually help restore confidence.

For now, however, the June results paint a picture of an Australian public that remains deeply cautious about the future, with many families continuing to navigate one of the most financially challenging periods in recent years.
