The Young Australian's Guide to Phones, Bills & Utilities

The Australian mobile market is split between the three major networks — Telstra, Optus and Vodafone — and a large number of MVNOs (Mobile Virtual Network Operators) that resell capacity on those same networks at significantly lower prices.

MVNOs include Boost Mobile (runs on Telstra), Belong (Telstra), Amaysim (Optus), Woolworths Mobile (Optus), Dodo (Vodafone), and many others. In most metro areas and major regional centres, the coverage difference between a premium carrier and its MVNO is negligible. You're largely paying for brand, customer service and priority on the network during congestion.

The two main plan structures:

• SIM-only plans — you provide your own phone and pay just for the service. This is nearly always cheaper than a handset plan and gives you full flexibility to switch providers without a contract. A SIM-only plan with 40–60GB of data, unlimited calls and texts costs $25–45/month from most MVNOs.
• Handset plans (contracts) — the phone's cost is bundled into a 24-month contract. Convenient, but the total cost over 24 months is almost always more than buying the phone outright and using a SIM-only plan. Run the numbers before signing.

Electricity bills confuse most people because they're written in a way that doesn't make it easy to understand what you're actually paying for or whether you're on a good deal. Breaking down the key components demystifies the bill.

Every electricity bill has two main charges:

• Supply charge (daily service charge): A fixed daily fee just for being connected to the grid — typically 80 cents to $1.20 per day. You pay this regardless of how much electricity you use. It's worth knowing because it's often where providers make money even on low-usage customers.
• Usage charge: The cost per kilowatt-hour (kWh) of electricity you actually use. In most states this is 25–40 cents/kWh, though prices vary by state, provider and tariff type.

Tariff types matter:

• Single rate (flat rate): The same price per kWh at all times. Simple to understand.
• Time-of-use (TOU): Different rates depending on the time of day — peak (typically 3pm–9pm weekdays), shoulder, and off-peak. If you can shift usage to off-peak (overnight, weekends), TOU tariffs can reduce your bill. If your usage is fixed, a single rate is often better.
• Controlled load: A separately metered circuit for high-consumption appliances (usually hot water systems) that runs at a significantly cheaper overnight rate. If you have a hot water system, check whether you're on controlled load — you may be missing out on cheaper rates.
