SAFE vs Convertible Note vs Equity for Australian Startups

TL;DR

• SAFE-style instruments, convertible notes and priced equity have different legal and economic characteristics in Australia.
• A convertible note is debt; equity financing issues shares; SAFE-style documents should be reviewed for local legal and tax treatment.
• Model future dilution before signing multiple instruments.
• Use qualified Australian legal and tax advisers before choosing or adapting a financing document.

How the financing structures differ

Founders often import terminology from US fundraising, but the legal effect of a document depends on the actual instrument and jurisdiction. The practical job is to understand what the company is issuing, how it affects ownership and what future investors will see.
