Are Electronic Signatures Legal in Australia? Complete Guide

November 20258 min read

Yes, electronic signatures are legally binding in Australia. This comprehensive guide explains the Electronic Transactions Act, when e-signatures are valid, and the few exceptions where traditional signatures are still required.

The Short Answer

Yes, electronic signatures are legally binding in Australia. Under the Electronic Transactions Act 1999 (Cth) and equivalent state legislation, electronic signatures have the same legal standing as handwritten signatures for most documents and transactions.

The Legal Framework

Electronic signatures in Australia are governed by several pieces of legislation:

Key Legislation:

  • Electronic Transactions Act 1999 (Cth)

    The federal law that establishes the legal validity of electronic signatures and documents

  • State and Territory Electronic Transactions Acts

    Each state has equivalent legislation (e.g., Electronic Transactions Act 2000 NSW, Electronic Transactions Act 2000 VIC)

  • Corporations Act 2001

    Contains specific provisions for electronic execution of company documents

Requirements for a Valid Electronic Signature

For an electronic signature to be legally valid in Australia, it must meet certain requirements under the Electronic Transactions Act:

1. Identification

The method used must identify the person signing and indicate their intention to sign

2. Reliability

The method must be as reliable as appropriate for the purpose of the document

3. Consent

The person receiving the document must consent to receiving an electronic signature

4. Integrity

The document should remain intact and unaltered after signing

AirSign meets all these requirements by providing secure signing with identity verification, tamper-evident certificates, and complete audit trails for every document.

Documents You Can Sign Electronically

The vast majority of business and personal documents can be legally signed electronically in Australia:

Employment contracts
Commercial agreements
Service agreements
Non-disclosure agreements
Residential tenancy agreements
Sales contracts
Client onboarding forms
HR documents and policies
Invoices and purchase orders
Terms and conditions
Loan agreements
Insurance applications

Exceptions: Documents That May Require Wet Signatures

While most documents can be signed electronically, there are some exceptions where traditional wet-ink signatures may still be required:

  • Wills and testamentary documents

    Most states require wills to be signed in wet ink with witnesses present (though this is evolving)

  • Powers of attorney (enduring)

    Some states have specific witnessing requirements that may not be satisfied electronically

  • Certain real property transactions

    While many property documents can be electronic, some jurisdictions have specific requirements

  • Court documents

    Affidavits and statutory declarations may have specific requirements depending on the court

Important: These exceptions vary by state and territory, and the law continues to evolve. If you're unsure about a specific document type, consult with a legal professional.

Witnessed Documents and E-Signatures

Many documents in Australia require a witness signature. Following COVID-19 pandemic reforms, remote witnessing is now accepted in many situations, though requirements vary by state.

AirSign's E-Witness feature enables compliant remote witnessing for documents that require a witness. The witness participates in the signing session, verifying the signer's identity and observing the signing process, with a complete audit trail recorded.

This is particularly useful for statutory declarations, certain legal agreements, and other documents where witnessing is required but in-person signing isn't practical.
