How much cash should you keep at home in Australia?

Cash sits on every Australian emergency kit list next to water and a torch, but no agency says how much. This guide does the sums from official ABS data, explains the AUSTRAC reporting rules and the low insurance limit on cash, and is honest about where gold does and does not fit.

How much cash should I keep at home in Australia?

Enough to buy essentials for a few days if cards, ATMs and online banking all stop working. That is a much smaller sum than many people imagine. The goal is not to replace your bank account. It is to buy food, medicine and perhaps fuel while systems are down.

To put a number on it, we used two official ABS data sets. The Monthly Household Spending Indicator shows Australian households spent A$12,653.7 million on food in August 2026 (seasonally adjusted). The ABS population estimate was 27,921,150 people at 31 March 2026. Dividing one by the other over August's 31 days gives about A$14.62 per person per day. We took three days of that and added a A$100 buffer for fuel, a pharmacy trip or a taxi. The buffer is our own assumption, not an official figure.

How we worked it out: A$12,653.7 million / 27,921,150 people / 31 days = A$14.62 per person per day, an average across all ages. Food for 3 days = A$14.62 x 3 x people. The ABS food category maps spending at supermarkets and similar retailers; cafes, restaurants and takeaway are a separate category. Prices keep rising, so round up rather than down.

Adjust for your own life. If you rely on a car in the country, have a baby who needs formula, or pay for regular medication, add those costs. If you live in a city and walk everywhere, you may need less.

Why do emergency services say to keep cash?

Because card payments depend on electricity, phone networks and the internet. In a bushfire, flood or cyclone, those can be down for days. The official lists put it plainly:

The same logic covers a bank's own IT failure or a cyber attack on a payment system. For what happens to your balance if a bank actually fails, see what happens if an Australian bank fails. Cash is one item on a longer list: our emergency kit checklist covers the rest.

Which notes should you keep?

Keep mostly small notes. In an outage a shop may not be able to give change for a A$100 note, so A$5, A$10 and A$20 notes plus some coins are more useful. The official lists do not name denominations, so this is practical advice, not an official rule.

• Old notes are still legal tender. The Reserve Bank of Australia says all previous issues of Australian banknotes keep their legal tender status, though some shops may be reluctant to accept them. The RBA and most commercial banks will redeem old notes at face value, so swap any paper notes for polymer ones.
• Keep it dry. A zip bag inside a sealed box protects notes from floodwater and smoke.

Is it illegal to keep cash at home?

We found no Australian law that limits how much cash you can keep at home. The rules people worry about apply when cash moves through a business.

• Threshold transaction reports. AUSTRAC requires reporting entities such as banks to report physical cash transactions of A$10,000 or more. Card payments, cheques and electronic transfers do not trigger these reports.
• Structuring is a crime. AUSTRAC says splitting cash transactions into smaller amounts to avoid reporting is a criminal offence, and businesses must report suspected structuring.

Practical tip: keep the withdrawal records that show where your home cash came from. That makes any later deposit simple to explain.

Will contents insurance cover cash at home?

Only a small amount. Contents policies usually set a separate, low limit for cash. One published example:

Your own policy may differ. Check the limits section of your PDS and ask your insurer whether cover can be increased.

So A$200 does not even cover the two-person example above, and a few thousand dollars in a biscuit tin is almost entirely uninsured if it is stolen or burnt.

What is the safest place to keep cash at home?

• A fixed safe. A safe bolted to the floor or a wall is far harder to carry off. A fire-resistant model also protects documents.
• Not the obvious places. Bedroom drawers, freezers and under the mattress are the first places burglars look.
• Split it. Keep a small amount in your evacuation bag and the rest locked away.
• Stay quiet. Do not mention home cash on social media, and tell only one trusted person where it is.

What does keeping cash at home cost you?

Cash in a drawer earns nothing while prices keep rising. The ABS reports the CPI rose 4.3% in the 12 months to September 2026. At that rate, A$250 of emergency cash buys about A$11 less a year later, and A$5,000 loses about A$215 of buying power. For a small emergency fund that is a fair price for peace of mind. For larger sums, a savings account covered by the Financial Claims Scheme usually makes more sense.

Cash, savings or gold: how do they compare?

Where does gold fit in?

Gold is not emergency spending money. You cannot buy groceries with a Kangaroo coin, and selling gold quickly needs a dealer and working payment systems, which are exactly what an outage takes away. If your goal is to get through a few days of disruption, cash is the tool.

Where gold can play a part is over years, not days. It is a physical asset you can own outright, outside the banking system, which is why some people turn to it when trust in banks or currencies is low. It also has real drawbacks: no interest, a price that can fall sharply, dealer margins when you buy and sell, and the same theft and insurance problems as cash if you keep it at home. Our guide to whether gold is a safe haven shows how it behaved in past crises in Australian dollars, and our gold storage guide compares home safes, bank boxes and vaults.
