The Australian Securities & Investments Commission has updated its guidance on advertising financial products and services, including credit, to clarify how firms can meet obligations not to make false or misleading representations or engage in misleading or deceptive conduct. The revised Regulatory Guide 234 now serves as ASIC’s main advertising guidance in this area and incorporates guidance previously contained in Regulatory Guide 53, which has been withdrawn. The update adds guidance reflecting enforcement and regulatory action relevant to advertising since Regulatory Guide 234 was first published in 2012, and simplifies and streamlines the existing material. It applies to promoters of financial products, financial services, credit products and credit services, as well as publishers of advertising. The changes follow consultation conducted from 27 November 2025 to 22 January 2026, with stakeholders broadly supportive of the proposed updates.
