Read the full editorial guide →For most Australian first-home buyers under $70 total, three purchases deliver the biggest power-bill cut. Start with the TP-Link Tapo P100 Smart Plug at around $20. Plug your TV / entertainment unit / phone chargers into it and schedule auto-shutoff overnight — standby power draws ~$80-150/year for a typical AU household's "always-on" devices, and the smart plug eliminates the entire standby phantom load with no behaviour change required. Pays itself back in 2-3 months. Buy 2-3 at $40-60 total to cover all major standby clusters (TV + bedside chargers + home office).
Complement it with the LUTW 9W Cool White E27 LED Bulbs (10-pack) at ~$17. Most AU rentals + new-builds ship with developer-grade incandescent or halogen bulbs that draw 60W each — replacing 10 bulbs with 9W LEDs saves ~$220/year at the AEMC May 2026 reference $0.32/kWh on typical 4-hour-per-night usage. Each LED lasts 10-15 years so this is genuinely a one-time spend. The cool-white 4000K is the right choice for kitchen + bathroom; if you prefer warm-white in bedrooms + living rooms, the same LUTW 10-pack ships in 3000K at the same price.
Round it out with the Door & Window Draught Excluder Twin Pack at ~$30. AU new-builds and 1960s-1990s rentals both have measurable draught gaps under exterior doors (2-5mm typically) that drive heating + cooling losses of $150-300/year. The self-adhesive twin pack covers the front + back door (the two highest-impact draught sources in most AU homes) and installs in 5 minutes per door. The 2-3°C indoor-temperature stability difference is genuinely felt within a week of install.
One honest limitation: these are the under-$70 quick wins — the deeper power-bill levers are appliance choice (heat pump vs vented dryer = $1,500+ lifetime difference), reverse-cycle vs portable AC ($600-1,200/year heating), and solar panels (5-8 year payback on AU rooftops). The picks above are the universal first-month interventions that pay back inside 12 months regardless of which bigger upgrades you make later — covered in the body of the full article above.
