About SunTariff

SunTariff is a plain, source-stamped reference for what electricity actually costs in Australia, and for costing solar decisions against the tariffs you really pay. Every price on the site is transcribed from an official determination, and each figure carries the name of that determination, the date it took effect, and a link back to the body that set it.

We built SunTariff because energy pricing here is public but rarely readable. Regulators publish it as long PDFs and technical schedules. We turn those into clean tables and calculators, so you can see the standing reference price for your area, estimate a typical bill, work out what an appliance costs to run, or check whether solar stacks up, without wading through a determination yourself.

SunTariff is published by Inventum, an Australian company. Articles carry the byline SunTariff Editorial. We work on a brand-as-author model: a named publisher stands behind the whole site, the way we source and calculate is written out in full on our methodology page, every dataset is dated, and mistakes get fixed through a single corrections inbox. We don't invent authors or personas. If a page is wrong, you're writing to the people who publish it.

What SunTariff is not: we're not an electricity retailer, a broker, or a comparison or switching service. We don't sell plans, we don't take a commission for sending you to anyone, and we're not affiliated with any regulator, distributor, or government body. The site carries advertising and basic analytics, kept entirely separate from the data. Ads never change a number.

One more thing worth knowing: every calculator and every page draws on the same pricing engine and the same committed datasets. The bill estimate you see on a state page and the one inside a calculator can't quietly disagree, because they're computed the same way from the same source.
