What are the security requirements for e-signatures in Australian financial services?

The Electronic Transactions Act 1999 (Cth) (ETA) provides the primary legal framework, requiring e-signatures to be reliable and appropriate for the purpose, particularly in financial services regulated by the Australian Securities and Investments Commission (ASIC). Reliability involves secure methods to identify the signer and indicate approval, aligning with standards like ISO 27001 for information security management.
