A winding-up application has been filed against the company behind Mondiaux Solar. That does not mean the company is in liquidation.
The legal entity is Mondiaux Pty Ltd, ACN 154 704 524. An application under the same Federal Court action number, NSD938/2026, was first published on 24 June 2026, naming the Deputy Commissioner of Taxation as plaintiff and an 8 July hearing. The current published notice, from 9 September 2026, names the Chief Commissioner of State Revenue as plaintiff, with the hearing now listed for 9:30am on 18 September 2026.
The record establishes that this is one continuing proceeding whose plaintiff and hearing date have changed since June, not two unrelated applications. It does not establish why the plaintiff changed.

The most important fact is that a winding-up application is on foot. Mondiaux has not been wound up on the basis of the public material reviewed.
A second relationship may matter
The Australian Energy Regulator continues to list a current retail exemption for Mondiaux Pty Ltd relating to electricity sales under power purchase agreements. Someone dealing with Mondiaux Solar may therefore have an installation relationship, a warranty issue, a finance arrangement, or a PPA relationship.

What the record establishes
A winding-up application under action NSD938/2026 is on foot. A hearing is listed for 18 September. The published plaintiff changed between the June and September notices. Mondiaux Solar remains a registered business name.
What it does not establish
Not a finding of insolvency. Amount claimed, whether disputed, the company's defence, its financial condition, why the plaintiff changed, and the hearing outcome are all unresolved.
If this affects you
Keep the installation agreement, PPA, warranty documents, finance documents, invoices, payment records and correspondence. Confirm whether the counterparty on your paperwork is Mondiaux Pty Ltd, ACN 154 704 524.
