What we found

Trading: Google still lists Smart Energy Answers as open (546 reviews); its website https://www.smartenergyanswers.com.au/ still loads; it had a SolarQuotes review on 26 October 2026.

Open for business: Google, its own website or recent reviews show it trading. A cancelled old name or ABN beside a business that plainly trades on is a restructure, not a closure.
