10 Money-Saving Hacks for Australian Households

With living costs remaining a top priority across Australia, taking a systematic look at your monthly recurring expenses can unlock substantial savings. Many households pay a 'loyalty tax' simply by staying on legacy contracts for energy, broadband, and insurance.

Here are 10 actionable, high-impact money-saving hacks designed to cut household overheads this month without compromising your lifestyle.

1. Benchmark Your Energy Plan Against the Reference Price

If you have been with your energy retailer for more than 12 months, you are likely paying more than necessary. Under Australian Energy Regulator (AER) rules in NSW, QLD, and SA, plans are compared against the Default Market Offer (DMO). In Victoria, the equivalent is the Victorian Default Offer (VDO).

Competitive market contracts regularly sit 15% to 25% below the reference price. Check your latest electricity bill for the comparison box. If your rate equals or exceeds the reference price, switch to a cheaper market offer immediately.

2. Check Your Eligibility for State Energy Rebates

State and federal governments provide a range of utility concessions that often go unclaimed. Automatic energy bill relief concessions help eligible concession cardholders, but other state-specific grants require an application:

• New South Wales: The Family Energy Rebate and Low Income Household Rebate.
• Victoria: The Annual Electricity Concession and energy efficiency upgrade discounts via the Victorian Energy Upgrades (VEU) program.
• Queensland: The Electricity Rebate and Home Energy Emergency Assistance Scheme.
• Western Australia & South Australia: State-based energy concession schemes administered through local human services departments.

Check with your state's concession authority to confirm your household receives every rebate you are entitled to.

3. Right-Size Your NBN Broadband Tier

Many Australian households pay for NBN 100 or NBN 250 download speeds when their actual usage never exceeds the capacity of an NBN 50 plan. A standard four-person home streaming 4K video, browsing, and working remotely generally operates smoothly on an NBN 50 plan (or even NBN 25 for smaller households).

Review your broadband provider’s customer portal to see your actual peak usage. Dropping one tier can save between $15 and $30 per month with zero perceived drop in performance.

4. Adjust Your Air Conditioning by Just One Degree

Space heating and cooling account for roughly 40% of average home energy consumption. In summer, set your thermostat to 24°C or 25°C. In winter, aim for 18°C to 20°C.

Every single degree closer to the outside temperature reduces the energy consumption of your reverse-cycle split system by roughly 5% to 10% over billing cycles.

5. Lower Your Hot Water Storage Temperature

Water heating is typically the second-largest energy consumer in Australian homes. Electric storage systems often come set from the factory at 70°C or higher.

While water in the tank must be stored at a minimum of 60°C to prevent bacterial growth (such as Legionella), dropping the thermostat from 70°C down to 60°C prevents overheating and reduces daily standby heat loss.

6. Target Standby 'Vampire' Power

Appliances left in standby mode—gaming consoles, older televisions, microwave displays, and desktop computer setups—can contribute up to 10% of your electricity consumption. Plugging home entertainment and home office setups into master-switched or smart powerboards lets you cut power to idle peripherals with a single tap.

7. Maximise Time-of-Use (ToU) Off-Peak Windows

If you have a smart meter and are on a Time-of-Use tariff, peak electricity hours generally run during late afternoons and evenings on weekdays. Off-peak and shoulder periods—especially daytime 'solar soak' windows between 10:00 am and 3:00 pm—feature much cheaper rates.

Set delay timers on your dishwasher, washing machine, and pool pump so they run during the cheapest daylight or overnight windows.

8. Challenge Your Insurers with Competitor Quotes

Comprehensive car and home insurance premiums rise regularly at renewal. Before accepting an automated renewal notice, run three comparison quotes online. Call your existing insurer, quote the cheapest competitor's price, and ask their retention team to match it. Retailers often shave 10% to 20% off the premium to keep your business.

9. Cash In on Container Deposit Schemes

Container deposit schemes operate across nearly all Australian states and territories (such as Return and Earn in NSW, CDS Vic in Victoria, and Containers for Change in QLD and WA). Returning aluminium cans, glass bottles, and juice cartons earns a 10-cent refund per eligible item. Storing and returning 150 containers each month adds $15 back into your pocket.

10. Audit Unused App and Streaming Subscriptions

Subscription creep is a hidden monthly drain. Review your bank statements for recurring micro-charges: unused streaming platforms, fitness apps, or cloud storage upgrades. Pause or cancel services you have not used in the past 30 days. You can easily resubscribe when a specific series or need arises.

Taking an afternoon to implement these checks can deliver over $100 to $200 in monthly relief, giving your household budget immediate breathing room.
