Quick read
- The Electronic Transactions Act helps businesses rely on electronic signatures, online records and digital communications, but it does not make every signing process safe.
- The business still needs proof of identity, authority, consent and an audit trail.
Likely relevant if
- Businesses signing contracts electronically
- Online businesses using clickwrap or digital acceptance flows
- Companies sending notices and records by electronic means
Check first
- Check whether the document or transaction is excluded from electronic signing rules.
- Use a method that identifies the signer and indicates their intention.
- Keep reliable evidence of consent, timing, version and authority.

When this shows up in real life
Signing customer contracts online

Common questions
Are electronic signatures valid in Australia?
Often yes, if the legal requirements are met and no exclusion applies. Some documents and jurisdictions have special rules, so check the transaction type.
Is clickwrap enough for online terms?
It can be, but the process must make the terms available and capture clear assent. Hidden terms or weak records are still risky.
