Why we think this

Closed because DELTA SOLAR AUSTRALIA PTY LTD (ACN 643163124) is under external administration (administrators or liquidators appointed); Business name DELTA SOLAR AUSTRALIA cancelled on 9 April 2026. Closure dated 9 April 2026, from ASIC business names: Business name DELTA SOLAR AUSTRALIA cancelled. Against that: Google still lists Delta Solar Australia Pty Ltd as open (1 review); ABN 68643163124 (DELTA SOLAR AUSTRALIA PTY LTD) is still active. Google and websites often lag a collapse, so the registers win.

The date comes from: ASIC business names: Business name DELTA SOLAR AUSTRALIA cancelled.

The business has stopped trading: a register, Google or the industry's review sites say so.
