How Building Licences Are Cancelled and Suspended in South Australia

What it is

Consumer and Business Services (CBS) can suspend, cancel or impose conditions on a South Australian building work contractor licence under the Building Work Contractors Act 1995 (SA). CBS operates on natural justice principles and issues formal decisions on disciplinary matters.

The Magistrates Court provides external review through its administrative review jurisdiction. SACAT does not have general review jurisdiction over CBS building licence decisions.

Grounds for cancellation

Sections 20 to 26 of the BWCA and CBS's disciplinary policy set out grounds for action:

• serious or repeated defective work
• unprofessional conduct
• misleading, deceptive or unconscionable conduct
• criminal convictions relating to the licensed activity
• financial failure or insolvency
• failure to maintain the nominated supervisor requirement
• failure to comply with a CBS undertaking or Magistrates Court order
• carrying on business without a licence in a period of suspension
• section 42 anti-avoidance breaches

CBS treats repeat customer complaints as an aggravating factor, particularly where the complaints go to workmanship or contract compliance.

Show cause notice

CBS issues a show cause notice setting out the grounds and the proposed action. The licensee has the prescribed period (typically 21 to 28 days) to respond with evidence, submissions and any undertakings.

CBS considers the response and issues a decision. Where the response addresses the concerns, CBS may accept an undertaking in lieu of formal action.

Possible outcomes

CBS can:

• take no action
• issue a written warning
• accept an undertaking
• impose licence conditions
• suspend the licence for a specified period
• cancel the licence
• disqualify the individual from being a director or nominee

Section 38 of the BWCA allows the Magistrates Court to grant relief against harsh, unconscionable or unjust contract terms; that is a related but distinct jurisdiction from licence discipline.

Magistrates Court review

A licensee can seek review through the Magistrates Court under the general administrative review framework. The court reviews the CBS decision de novo and can affirm, vary or set aside.

Legal representation is permitted; hearings involve evidence on the disciplinary grounds and the appropriateness of the sanction.

Interaction with BII

Where the licence is cancelled or suspended, Building Indemnity Insurance under section 34 of the BWCA is affected. Existing certificates may be affected depending on cancellation grounds. Consumers can claim on BII where the cancellation flows from a trigger event (death, disappearance, insolvency).

CBS notifies SAFA of licence changes so the insurance framework tracks the licensing framework.

The 10 November 2025 reforms context

The 10 November 2025 reforms raised the BII trigger to $20,000 and the minimum cover to $250,000. Those changes interact with the disciplinary framework because BII compliance is now a more significant licence obligation. A licensee that fails to hold BII where required faces both a BWCA offence and disciplinary action.

Consequences of cancellation

A cancelled licensee cannot:

• carry on business as a building work contractor in South Australia
• act as a nominated supervisor
• be a director or nominee of another licensed contractor for the disqualification period

The cancelled licensee may face civil recovery from SAFA for any BII payouts flowing from cancellation. Directors and shadow directors can be personally liable.

How South Australia compares

SA's CBS / Magistrates Court framework differs from the tribunal-based frameworks in NSW, VIC and QLD. The Magistrates Court review jurisdiction is unusual for building licence matters (most states use their general administrative tribunal). SACAT handles building disputes at the consumer-contract level but not licensing discipline.

TradeForm SA templates flag the disciplinary risk to owners and builders, particularly the interaction between the section 5 business-of-contracting requirement and the section 34 BII compliance obligations.
