IAF ETF: How Ishares Core Composite Bond ETF Works
Last updated: 2026-08-29
The IAF ETF, or the iShares Core Composite Bond ETF to use the full name, gives investors exposure to investment-grade Australian fixed income. For Australian investors, the key question is not just what the fund holds, but whether it works as the right defensive portfolio building block compared with alternatives like VAF, VGB or even cash-style ETFs.
What it does: Broad exposure to investment-grade Australian bonds via a single ASX-listed ETF.
Who it may suit: Investors looking for a core defensive allocation rather than a pure cash holding.
Main local issue for Australians: The big decision is usually not access, but whether to choose a broad bond ETF, a government-bond ETF, or a cash ETF instead.
Best Australian-listed alternative: VAF is the closest like-for-like rival; VGB and AAA suit different defensive roles.
Can Australians buy this ETF?
Short answer: Yes. IAF is an Australian-domiciled ETF listed on the ASX and designed specifically for local investors.
Australian investors should check four things before buying this ETF:
- Where it is listed: ASX
- Fund domicile: Australia
- Whether there is an ASX or Cboe Australia equivalent: Yes, VAF is the closest local rival, while VGB and AAA are adjacent defensive alternatives.
- Whether the exposure is hedged or unhedged to AUD: The portfolio is already mostly in Australian-dollar bonds, so foreign currency risk is not the main issue here.
For most Australians, access is straightforward. IAF trades on the ASX, is Australian-domiciled, and BlackRock Australia provides the usual local issuer documentation including the PDS and TMD.
The more important portfolio question is whether you want broad Australian fixed income, a government-bond-heavy defensive sleeve, or something closer to cash. That is where IAF needs to be compared with products like VAF, VGB and AAA.

IAF ETF at a glance
IAF is designed for income and portfolio defence, not for equity-like capital growth. Investors should judge it more on yield, drawdown behaviour and diversification value than on raw return compared with shares.
What does the ETF actually do?
IAF aims to provide investors with the performance of the Bloomberg AusBond Composite 0+ Yr Index, before fees and expenses. That index is designed to measure the broad Australian bond market and includes investment-grade fixed income securities issued by the Australian Treasury, Australian semi-government entities, supranational and sovereign issuers, and corporate issuers.
For Australians, that makes IAF a practical way to get a core local bond allocation in one trade. Instead of buying individual bonds or relying on term deposits and cash alone, investors can use IAF to access a diversified basket of Australian investment-grade bonds.
What IAF is not is a cash ETF, a high-yield bond ETF, or a pure government-bond ETF. It sits in the middle: broader than government-only exposure, but higher quality than credit-heavy income products.
What is inside the fund?
IAF holds a broad mix of Australian bond exposures across government, semi-government and corporate issuers. That diversification matters because the fund is designed to represent the broader Australian fixed income market rather than one narrow corner of it.
Overview
Ishares Core Composite Bond ETF (IAF) is a broad Australian bond ETF designed to give investors diversified exposure to the local fixed income market. With a large fund size and a low-fee structure, it sits in the core part of the bond allocation toolkit rather than trying to make a bold active call on rates or credit.
Category
IAF sits in the centre of the Australian bond market story: it is built around government and other high-quality debt, with the portfolio anchored by Australian Commonwealth Government securities. That makes it a straightforward way to express a view on domestic fixed income without having to pick individual issuers or maturities.
For Australian investors, bond ETFs like IAF are often used to bring stability, income and diversification to a portfolio that may otherwise lean heavily on equities. The fund’s quarterly distributions and broad sovereign-heavy exposure can make it appealing when the market is focused on capital preservation, yield and the role fixed income plays alongside shares. At the same time, bond returns can remain subdued when yields move higher, which helps explain why long-run performance can look modest even when the fund’s income profile remains intact.

Related ETFs
Compared with more targeted bond ETFs, IAF is positioned as a broad core holding rather than a niche satellite. Its low 0.24% fee and large AUM of $3.774 billion support that role, while the top holdings show a portfolio concentrated in a small set of Australian government bonds rather than a wide scatter of individual credits.

Risks
Who it may suit
IAF may suit investors who want a simple Australian bond allocation, are looking for regular income, and prefer a fund that is built around high-quality domestic debt. It may also appeal to those using ETFs to balance equity risk with a more defensive asset class.
Key risks
The main risk is interest-rate sensitivity: as a bond fund, IAF can lose value when yields rise. Investors should also be aware that its performance has been modest across several horizons, with returns of 0.64% over 1 year, 3.69% over 3 years, -0.26% over 5 years and 1.47% over 10 years. Concentration is another consideration, even though the fund is broad overall, because the top 10 holdings account for 18.67% of the portfolio.
