Key differences at a glance
Neither COMP nor IAF is the "right" pick for everyone; it comes down to what you want from the holding. Where they differ most:
Green highlights the leading comparison score, the factually lower fee, or the higher scale or income figure. Performance is never highlighted. Data from issuer disclosures and the ASX Investment Products report. Fund size, yield, return and holdings figures each state the date they are as at.
Category scores compare these two ETFs only and are not absolute ratings.
Cost (management fee): COMP has the lower management fee - the one objective "cheaper" axis.
Fund size (assets): IAF is the larger fund. Larger is not inherently better, but greater scale can support tighter spreads and lower closure risk.

IAF top holdings
Whether COMP or IAF fits comes down to your goals, time horizon and what you already hold. The clearest differences are summarised near the top of this page, with the full data below.
COMP and IAF do not share enough listed top holdings to reliably estimate a holdings overlap. Compare their fees, holdings and sectors on this page.
COMP has the lower management fee. COMP charges 0.07% per year ($7 per year on a $10,000 investment) and IAF charges 0.1% per year ($10 per year on a $10,000 investment). The difference is $3 per year per $10,000 invested.
COMP (Betashares Bloomberg Ausbond Composite ETF) manages approximately $9.39M and IAF (iShares Core Composite Bond ETF) manages approximately $3.7B. Fund sizes as at 30 Sep 2026 for both funds. Fund size can affect liquidity and bid-ask spreads but does not by itself change the management fee.
COMP and IAF do not share enough listed top holdings to estimate overlap, so whether holding both duplicates your exposure depends on their full constituent lists.
There is no universally right choice. It depends on your goals, time horizon and existing holdings. COMP charges 0.07% and IAF charges 0.1%, so COMP has the lower management fee. Compare their fees, holdings and sectors above and consider each fund's Product Disclosure Statement and Target Market Determination.
General information only. This comparison and the ETFLens tools on this page provide general information about two exchange-traded funds and do not take into account your personal objectives, financial situation or needs. It is not personal financial product or investment advice. ETFLens does not hold an Australian Financial Services Licence (AFSL). Holdings overlap is calculated from each fund's published holdings (full lists where the issuer publishes one, listed top holdings otherwise), and fee data is sourced from fund manager PDS documents. Past performance is not a reliable indicator of future returns. Consider each fund's Product Disclosure Statement (PDS) and Target Market Determination (TMD), and seek advice from a registered tax agent or licensed financial adviser, before making investment decisions.
