New ING research reveals Australians are adopting extreme cost-cutting measures in 2025, with 30% willing to take cold showers and switch off air conditioning despite heatwaves to reduce energy bills. Other significant savings strategies include meal prepping, buying wonky produce and marked-down groceries, and cancelling streaming services in favour of free community activities. The research identifies energy usage, food and groceries, and entertainment as the three main areas where Australians are focusing their savings efforts.
