About Big Aus

Big Aus publishes research, tools and guides for the decisions Australians actually make: solar, batteries, property, home energy, and the bigger consumer choices where the answer is rarely the one a comparison site serves up.

Why another comparison site?

Most Australian comparison sites run on the same business model: capture your details, sell the same enquiry to three different installers or brokers, and optimise ranking by which advertiser pays the most. It's why iSelect was fined $8.5M by the ACCC for misleading energy comparisons, and why the category has a trust problem.

We think there's space for a different approach: exclusive referrals, transparent methodology, and content written with one goal — help you make a decision you won't regret, whether or not we earn a fee.

What we publish

• Calculators and tools that model your specific situation (postcode, tariff, DNSP, rebate stack) rather than generic averages
• Guides written after reading the primary source (the Clean Energy Regulator, state scheme pages, DCCEEW) — not recycled from competitor content mills
• Plain-English explanations of the rules that actually affect the dollars you receive

How we make money

See the dedicated How We Make Money page. Short version: exclusive installer and broker referral fees, no lead-sale roulette, no sponsored results dressed as recommendations.
