What we found
Trading, restructured: Business name STEADFAST SOLAR cancelled on 4 October 2025, but the business is plainly still trading (Google still lists Steadfast Solar as open (101 reviews); its website http://steadfastsolar.com.au/ still loads; it had a SolarQuotes review on 16 September 2026; ABN 55687452348 (IRON ROCK CO PTY LTD) is still active; ABN 69624016780 (PROSKUNEO PTY LTD) is still active). Nothing says the old one failed, so this reads as a move to a new name, ABN or company, not a closure.
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.
