Addicted to Money – Spend smarter, live better.

If there’s one thing quietly draining Aussie wallets in 2025, it’s bill shock. Even with cost-of-living pressures rising, most households are unknowingly overpaying hundreds to thousands of dollars a year on basic bills.

Here are the seven bills Australians overpay for the most — and exactly how to fix them.

 

1. Electricity & Gas — The Silent Budget Killer

Energy prices continue to spike, and many Australians are stuck on outdated plans with expired discounts.
Average overpayment: $300–$800 per year.

How to fix it:
• Compare every 12 months using Energy Made Easy or your state/territory’s regulator.
• Avoid “loyalty tax” by switching providers when discounts end.
• If you live rural or regionally and only have one provider, you still have options:
Check what tariff you’re on (e.g. peak, off-peak, time-of-use) and ensure it aligns with when your household actually uses the most energy.
A simple tariff change can reduce costs instantly.

Small changes like LED bulbs, timers, and government rebates can also cut usage.

 

2. Internet & Phone Plans — Loyalty Doesn’t Pay

The big telcos rely on customers sticking around. Welcome discounts disappear; your prices rise.
Average overpayment: $240–$600 per year.

How to fix it:
• Never let expired promo rates roll over.
• Compare providers like Kogan, Mate, Moose Mobile, Circles.Life — often half the price.
• Call your current provider and ask them to price-match a better deal.
• And don’t forget: some prepaid plans offer better bang for your buck with more data for less money and no contracts.

 

3. Insurances — The Worst Offender for Price Creep

Car, home, health and pet insurance premiums rise every single year simply because insurers expect customers not to switch.
Average overpayment: $300–$1,200+ per year.

How to fix it:
• Re-quote at every renewal.
• Use iSelect, Compare the Market, and Canstar.
• Increase your excess to lower premiums if your budget allows for higher out-of-pocket costs.

 

4. Subscriptions — The Sneaky Monthly Drip

From streaming services to apps to gym memberships, subscriptions add up fast.
Average overpayment: $200–$500 per year.

How to fix it:
• Do a monthly “subscription audit.”
• Cancel anything unused in the last 30 days.
• Share plans (where allowed).
• Turn off auto-renew for non-essentials.

 

5. Banking Fees — Mostly Avoidable

Account-keeping fees, transaction fees and ATM fees still drain money unnecessarily.
Average overpayment: $60–$180+ per year.

How to fix it:
• Ask your bank if they offer different account types with lower or no fees.
• Switch to paperless statements to avoid extra charges.
• Compare fee-free banks like Up, ING, Macquarie or Bendigo if your current bank refuses to budge.

 

6. Car Expenses — Fuel, Servicing & Regos

Fuel prices fluctuate weekly and servicing costs vary massively.
Average overpayment: $200–$700 per year.

How to fix it:
• Use apps like Fuel Map Australia or MotorMouth to find the cheapest station.
• Compare mechanics — dealership servicing isn’t automatically cheaper or better.
• Budget for rego and insurance per pay cycle, so you can pay annually and save compared to monthly or quarterly payment fees.

 

7. Groceries — The Biggest Weekly Blowout

Supermarkets mark items up, rotate specials, and rely on impulse buying.
Average overpayment: $30–$80 per week.

How to fix it:
• Meal plan every week.
Choose your meals first.
Make a list of ingredients.
Only buy what you actually need.
• Shop ALDI for basics and use Coles/Woolies for half-price deals.
• Use Click & Collect to avoid impulse spending.
• Always eat before you shop — hunger equals overspending.

 

The Bottom Line

You don’t need to live frugally or cut the fun out of life to save money — you just need to stop overpaying for the essentials. By reviewing these seven bills regularly and making a few smart changes, most Aussie households can save $1,500–$3,500 per year with minimal effort.
