A stash of cash can save the day.

Having a stash of cash can be useful in situations where technology fails and access to digital payment systems is temporarily unavailable. While most Australians primarily use cards for everyday payments, incidents like the recent CrowdStrike outage highlight the importance of having some cash as a backup. However, it's also recommended to have an emergency fund to cover unplanned expenses, such as job loss or health issues. The amount needed for an emergency fund varies depending on individual circumstances, and it's advisable to keep the funds in easily accessible accounts rather than investments.
