Australian investors choosing to add bonds to their portfolio face a key decision: buy a bond ETF (like VAF or VGB) that holds hundreds of bonds at once, or buy individual bonds directly on the ASX. Both approaches have merit — the right choice depends on your portfolio size, objectives, and how much complexity you want to manage.
Bond ETFs — What They Are
A bond ETF is a fund traded on the ASX that holds a diversified portfolio of bonds — typically dozens to hundreds — across various maturities and issuers. Examples:
- VAF: ~180 Australian government and investment-grade corporate bonds
- VGB: ~65 Australian government bonds only
- VBND: Global bonds, currency-hedged to AUD
You buy units in the ETF; the fund manager buys and manages the underlying bonds. Returns flow to you as monthly/quarterly distributions.
Direct Bonds — What They Are
Buying direct bonds means purchasing individual bond securities:
- ASX-listed Treasury Bonds (GSBA, GSBB, etc.) — specific government bonds by maturity
- ASX-listed corporate retail bonds (e.g., Woolworths Bonds, Transurban bonds)
- Over-the-counter (OTC) bonds — typically wholesale ($500,000+), not relevant for most retail investors
Side-by-Side Comparison
| Feature | Bond ETF | Direct bonds |
|---|---|---|
| Diversification | Immediate (100s of bonds) | Limited (buy 1 bond at a time) |
| Liquidity | High — trades daily on ASX | Variable — some ASX bonds thinly traded |
| Capital guarantee | No — price fluctuates | Yes, if held to maturity |
| Maturity control | No set maturity (perpetual fund) | Exact maturity date; principal returned |
| Minimum investment | ~$50–$100 (one unit) | ~$1,000–$5,000 |
| MER / cost | 0.15–0.32%/year | No MER; only brokerage per trade |
| Management | Passive — fund manages reinvestment | Active — you manage each maturity |
| Suitable for | Most investors | Bond ladders; maturity-specific income needs |
The Key Difference: Maturity and Capital Certainty
The single biggest difference: Bond ETFs have no fixed maturity date — they roll bonds as they mature, perpetually maintaining a portfolio of bonds. This means:
- The ETF’s unit price fluctuates indefinitely with interest rate changes
- There is no date at which you are guaranteed your capital back
- Price may be above or below your purchase price at any time
Direct bonds held to maturity do return your principal on the maturity date — regardless of what interest rates have done. If you buy a 5-year Treasury Bond at face value, you receive your full investment back in 5 years plus coupons along the way.
Practical implication: If you need certainty of capital at a specific future date (e.g., funding retirement income in 5 years), direct bonds held to maturity deliver this. A bond ETF does not.
When to Choose a Bond ETF
- You want portfolio diversification without managing individual bonds
- Liquidity is important (you may need to sell before maturity)
- You’re adding a defensive allocation to a long-term portfolio
- You want the simplest implementation
- Portfolio is < $100,000 (where diversification benefit of ETF is highest relative to cost)
When to Choose Direct Bonds
- You want capital certainty at a specific future date
- You’re building a bond ladder for retirement income
- Portfolio is large enough to buy multiple bonds for diversification (typically $200,000+)
- You want to precisely match bond maturities to future known expenses
- You want to avoid ongoing MER (for large amounts, this can be meaningful)
Using Both Together
Many sophisticated investors use both:
- Bond ETF (VAF/VGB): Core defensive allocation — liquid, diversified, simple
- Direct Treasury Bonds: Specific rungs of an income ladder — maturity-matched to known future expenses

Frequently Asked Questions
Are bond ETFs safer than individual bonds? Bond ETFs provide more diversification than a single bond — reducing credit risk from any one issuer defaulting. However, bond ETFs have no fixed maturity and their price fluctuates with interest rates. An individual government bond held to maturity returns its exact face value — making it more capital-certain for that specific date. Both carry interest rate risk if sold before maturity.
Do bond ETFs pay interest in Australia? Yes — bond ETFs pay distributions from the interest (coupon) income collected from the underlying bonds. VAF and VGB pay distributions monthly. The distribution amount varies as the composition of the portfolio changes and as bonds mature and are replaced.
What is better for a retiree — a bond ETF or direct bonds? For retirees wanting regular income and liquidity, bond ETFs (VAF) are practical. For retirees wanting certainty of capital at specific dates (to fund known expenses), direct bonds or a bond ladder approach offers more precision. Many financial advisers suggest using both in combination — ETF for the liquid defensive allocation, direct bonds for the income ladder.
