How Convertible Notes Work In Australia

Raising capital can feel like a chicken-and-egg problem. You need funds to grow, but you want to avoid locking in a valuation too early or giving up too much control.

That’s where convertible notes often come in for Australian startups and small businesses. They’re a flexible way to bring investors on board now, with equity conversion later.

In this guide, we’ll unpack how convertible notes work in Australia, the key terms you’ll negotiate, the legal framework you need to follow, and a practical step-by-step path to run a clean, investor-ready note round. We’ll also cover where notes fit alongside equity rounds and SAFEs so you can choose what’s right for your business.

What Is A Convertible Note (In Plain English)?

A convertible note is a short-term loan from an investor that can convert into shares in your company later, usually at your next equity round.

Instead of valuing your company today, you agree on a set of terms (like a discount or valuation cap) that determine how many shares the investor gets when the note converts. Until then, it’s typically recorded as debt.

For many founders, a note can be a faster, simpler way to raise capital than a full priced equity round-especially in the early stages when valuation is hard to pin down.

Why Do Australian Small Businesses Use Convertible Notes?

• Speed to cash: You can usually close a note faster than a full equity round.
• Defers valuation: You avoid negotiating a hard valuation too early.
• Flexibility: You can set a maturity date and conversion triggers that suit your growth plans.
• Bridges to a priced round: Notes are commonly used as “bridge” funding to your next raise.
• Investor alignment: Discounts and caps reward early investors for taking on more risk.

Of course, a note still needs to be structured properly. The right terms can set you up for a smooth conversion later. Poorly drafted terms can create headaches, disputes, or unexpected dilution.

How Do Convertible Notes Work? Key Terms Explained

Every convertible note is slightly different, but most revolve around the same core concepts. Here’s what to know-and what you’ll likely negotiate.

Principal

The amount invested under the note. This is the “loan” that will convert into shares later (unless it’s repaid or redeemed).

Maturity Date

The date by which the note must either convert, be extended, or be repaid/redeemed (depending on your note terms). Common maturities are 12-24 months.

Interest

Some notes accrue interest (simple or compounding). Interest can be paid in cash or convert into equity alongside the principal. Zero-interest notes also exist.

Conversion Triggers

• Qualified financing: If you raise a priced equity round above a threshold (e.g. $1m), notes convert automatically at that round’s share price, minus the discount or with the cap applied.
• Non-qualified financing: If you raise below the threshold, conversion may be optional or follow a different formula.
• Maturity: If a priced round hasn’t occurred by the maturity date, notes may convert at a pre-agreed price, be extended, or be repayable.
• Change of control: On a sale of the company, the note might convert at a specified price or repay with a premium-this is highly negotiable.

Discount

A percentage discount on the share price in the next equity round. For example, with a 20% discount, if new investors pay $1.00 per share, noteholders convert at $0.80 per share.

Valuation Cap

A ceiling on the company valuation used to calculate the conversion price, protecting early investors if your valuation climbs quickly. Many notes use a discount and a cap, with conversion occurring at the better (lower) price for the investor.

Most Favoured Nation (MFN)

An MFN clause may allow a noteholder to adopt more favourable terms if you later issue notes on better terms to someone else.

Redemption Rights

Some notes allow investors to call for repayment at maturity (often with a premium). Others are “mandatory convert” at maturity. Redemption rights can affect cash flow risk, so model them carefully.

Security

Most early-stage notes are unsecured. If security is proposed, be aware this can impact future financing and your ability to raise from other investors or lenders.

What Laws Apply To Convertible Notes In Australia?

Convertible notes are securities. That means you need to consider fundraising rules, disclosure requirements and corporate governance obligations under Australian law.

Fundraising And Disclosure

When offering notes, you usually rely on disclosure exemptions under Section 708 of the Corporations Act (e.g. offers to sophisticated or professional investors, or small-scale personal offers). These determine whether you need a prospectus or can raise privately.

Understanding who qualifies as sophisticated investors or professional investors is essential before circulating term sheets or note documents.

Company Governance

Once notes convert, investors will likely join your cap table. This has implications for your Company Constitution, voting rights, pre-emptive rights, drag/tag provisions and information rights. Aligning your note terms with your governance documents avoids conflicts down the track.

Consumer And Unfair Contract Laws

Although investment contracts largely sit outside the Australian Consumer Law (ACL) in a typical startup raise, unfair contract terms rules can still loom large in certain contexts. Keep terms fair, clear and fit for purpose, especially if dealing with non-institutional investors.

Tax And Accounting Touchpoints

Convertible notes can raise complex tax considerations (for both you and your investors), and they affect how your liabilities and equity are presented in your accounts. It’s wise to pair legal documents with advice from your accountant so your note structure and cap table modelling line up with your commercial goals.

Convertible Notes Vs SAFEs Vs Priced Equity: Which One Fits?

Notes, SAFEs and priced equity each serve different needs.

• Convertible Notes: Debt that converts later, usually with a discount/cap and a maturity date. Good when you need flexibility and timing pressure to close a later round.
• SAFEs: A hybrid contract that converts to equity without interest or maturity (depending on the form). Many founders like the simplicity of a SAFE note, but investors sometimes prefer the structure of a note with a maturity date.
• Priced Equity: A full round at an agreed valuation (e.g. seed, Series A). Clean, but more time-consuming to negotiate and document at the early stage.

If speed and flexibility are your priorities, a note can be a practical bridge to a later priced round. If you have strong momentum and investor appetite to set a valuation now, a priced round may be cleaner. Your choice should reflect your runway, investor expectations and growth plan.

What Documents Do I Need For A Convertible Note Round?

You’ll typically prepare a short set of documents that balance speed with clarity.

• Term Sheet: A concise, non-binding summary of the key commercial terms (discount, cap, maturity, triggers). This gets everyone on the same page quickly.
• Convertible Note: The core legal agreement setting out repayment, conversion mechanics, investor rights and event outcomes.
• Cap Table Model: A spreadsheet that shows how notes convert under different scenarios (with and without caps/discounts). This avoids surprises at conversion.
• Shareholders Agreement: If you don’t have one, or if new investors will join at conversion, align your governance (pre-emptive rights, information rights, vesting and founder protections).
• Company Constitution (or amendments): Ensure your constitution and the note terms work together-particularly around issuing new shares, classes of shares and pre-emption.
• Follow-On Equity Documents: When the note converts at a priced round, you’ll use your Share Subscription Agreement and related round documents to issue the shares.

If you plan to reward staff with equity, consider how your Employee Share Option Plan interacts with note conversions so you maintain the right incentives and headroom on your cap table.

Step-By-Step: Running A Clean Convertible Note Raise

1) Map Your Raise Strategy

Clarify how much you need, how long it should last (runway), and what milestones it funds. If the raise is a bridge to a later priced round, identify the key metrics you want to hit before that round.

2) Confirm Your Investor Pool And Eligibility

Check which disclosure exemption applies (e.g. sophisticated or professional investors under Section 708 of the Corporations Act). This is essential before circulating offers.

3) Align Your Governance

Make sure your company structure, constitution and any existing investor rights are consistent with issuing notes now and equity later. If you have co-founders, a solid Shareholders Agreement protects everyone and speeds up decisions.

4) Prepare A Clear Term Sheet

Use a concise Term Sheet to agree headline terms quickly. Clarity now saves time-and costs-later.

5) Draft And Issue The Convertible Note

Move from LOI/term sheet to the full note document. Keep terms consistent, ensure conversion math is unambiguous, and avoid hidden traps (like unexpected redemption rights or conversion quirks at maturity).

6) Close, Record And Track

Collect signatures, funds, and update your cap table model. Keep an organised folder with executed notes, investor certificates and board approvals.

7) Communicate And Deliver

Share a high-level plan with your investors and keep them updated. Transparency builds trust and sets you up for a smoother priced round when the time comes.

Common Pitfalls (And How To Avoid Them)

• Overlooking eligibility rules: Offering notes without relying on the right fundraising exemptions can cause serious compliance issues.
• Unclear conversion mechanics: Ambiguity on discount vs cap, or how non-qualified financings convert, drives disputes later.
• Ignoring maturity: Leaving maturity to the last minute can force poor choices. Build in clear options and plan ahead.
• Misaligned governance: If your constitution and shareholder arrangements don’t match your note terms, expect friction at conversion.
• Cap table surprises: Model multiple scenarios so you understand dilution before you sign.
• One-size-fits-all documents: Templates from other jurisdictions often don’t reflect Australian law or your specific deal dynamics.

Negotiating Better Terms: Founder Tips

• Balance discount and cap: A reasonable discount with a realistic cap often satisfies both sides-rewarding early risk without over-diluting founders.
• Clarify maturity outcomes: Decide whether notes convert or can be redeemed at maturity. If redemption is possible, consider your cash flow risk.
• Keep it simple: Avoid complex bespoke mechanics that slow down closing or confuse future investors.
• Protect headroom: If you have an options pool now (or plan to implement one), ensure your cap table can absorb future grants without over-dilution.
• Plan for “what if” scenarios: Write down how your notes behave on a smaller-than-expected round, a sale, or delays.

When Is A Convertible Note Not The Right Fit?

A note may not suit you if:

• You want investor alignment and governance now (e.g. board seats, reserved matters) that are usually negotiated in a priced equity round.
• Your investors strongly prefer a fixed valuation today (reducing uncertainty for them later).
• You have a complicated cap table already-another layer of debt that later converts could create friction.
• Your business model or growth plan requires long-dated capital with no clear priced round on the horizon.

In these cases, a priced equity round-or a SAFE note-might be a better tool. If you’re unsure, a quick chat can help you choose the right path for your goals.

How Much Legal Work Is Involved?

Compared to a full equity round, convertible notes generally involve fewer documents and a shorter negotiation cycle. But “lighter” doesn’t mean “loose.” You still want tight terms, aligned governance and a clean paper trail so your next round proceeds smoothly.

If you’re gearing up for a larger raise, you might also look at your broader capital raising for startups strategy so your note terms anticipate the equity round that follows.

Frequently Asked Questions

Can I Raise From Retail Investors Using Notes?

In most early-stage raises, you’ll rely on disclosure exemptions for private offers to sophisticated/professional investors or within the small-scale personal offers exemption. Get advice before approaching retail investors.

Do Notes Always Accrue Interest?

No. Some notes are zero-interest, others include a simple or compounding rate. If interest accrues, decide whether it converts into equity or is paid in cash.

What Happens If We Don’t Do A Priced Round Before Maturity?

Your note should set out what happens at maturity-common outcomes include forced conversion at an agreed price, extension by agreement, or redemption. Clarity here is critical.

How Do We Reflect Conversion In Our Equity Documents?

Once a priced round occurs, conversion is documented through your equity round paperwork (for example, your Share Subscription Agreement) and share issue processes. Your cap table should then be updated to reflect new holdings.
