Yes, e-signatures are legally valid for most strata management documents in Australia under the Electronic Transactions Act 1999 (Cth) and equivalent state legislation, such as the Electronic Transactions Act 2000 (NSW). These laws recognize electronic signatures as equivalent to wet-ink signatures provided they meet requirements for reliability, identity verification, and intent to sign. Exceptions may apply to specific documents like wills or land titles, which require traditional execution methods under strata schemes legislation like the Strata Schemes Management Act 2015 (NSW).
