AAA ETF Review: Betashares Australian High Interest Cash ETF (2026)

Last updated: Q2 2026. Figures are computed from ETFLens data as at Q2 2026, sourced from the issuer's published disclosure documents and reviewed quarterly.

The AAA ETF, the Betashares Australian High Interest Cash ETF, is one of the ways Australian investors hold cash inside a brokerage account rather than a bank. It is not a growth investment; it is a place to park money at a return close to short-term interest rates, with the convenience of trading on the ASX. This review explains what AAA holds, what it yields, what it costs, and the one thing that most often trips people up: it is not the same as a bank deposit.

What AAA actually holds

AAA holds Australian-dollar cash and short-term deposits placed with selected banks. Its stated aim is to deliver a return above the 30-day Bank Bill Swap Rate (BBSW), a common benchmark for short-term Australian interest rates, after fees. As at Q2 2026 it holds approximately 9 positions and manages approximately $5.2 billion, making it one of the larger cash funds on the ASX.

Because it holds cash and deposits rather than shares or long-dated bonds, its unit price is designed to stay stable, and its return comes almost entirely from the interest it earns, paid out as monthly distributions. That is a very different return profile from a share ETF, where most of the long-run return has historically come from capital growth.

The yield: real, but rate-dependent

As at Q2 2026, ETFLens shows a trailing distribution yield of approximately 3.9%. The single most important thing to understand about that number is that it moves with interest rates. A cash ETF earns roughly the prevailing short-term rate, so when the Reserve Bank raises or cuts rates, the yield follows within a matter of weeks. The trailing figure tells you what AAA paid over the past year, not what it will pay next year.

Past performance is not a reliable indicator of future returns, and the distribution is not guaranteed; it varies each month with rates. That is why comparing a cash ETF's headline yield against a share ETF's yield is not like-for-like: one tracks interest rates and the other reflects company dividends and a different risk profile entirely.

Fees: a bigger slice on a low return

AAA charges 0.18% p.a., which is approximately $18/year per $10,000. In absolute terms that is a small fee, but on a cash product it deserves a closer look than it would on a growth fund. When the gross return is a few per cent, a fee of 0.18% takes a more noticeable share of it than the same fee would on a fund returning much more. It is worth comparing that net-of-fee return against what a high-interest savings account or term deposit would pay, since those can sometimes offer a comparable rate with a government guarantee. The Fee Analyser shows the dollar impact.

The catch: AAA is not a bank deposit

This is the most important point in the review. AAA is a managed fund that holds bank deposits, but it is not itself a bank deposit. That means it is not covered by the Australian Government's Financial Claims Scheme, which protects deposits up to $250,000 per account holder per institution if a bank fails. A savings account or term deposit at an Australian bank carries that protection; a cash ETF does not.

In practice AAA's capital is relatively stable, because cash and short-term bank deposits are low-risk assets, but relatively stable is not the same as guaranteed. If capital safety backed by the government guarantee is your priority, a savings account or term deposit does something a cash ETF cannot. If day-to-day liquidity inside your brokerage account matters more, a cash ETF does something a term deposit cannot. Neither is better; they are different tools, and our ETFs vs term deposits guide compares them directly.

Distributions: monthly income

AAA pays distributions monthly, more frequently than most ASX share ETFs, which typically pay quarterly or semi-annually. For an investor using a cash ETF as a place to hold liquid money, that regular monthly income can be convenient. The amount changes each month with prevailing interest rates and is not guaranteed. You can see estimated dates on the distribution calendar.

How AAA may fit a portfolio

A cash ETF is generally used for the cash part of a plan rather than the growth part. Common uses include holding money set aside for a known near-term expense, keeping a portfolio's cash allocation inside a brokerage account rather than moving it to a separate bank, or parking funds between investments. It is not designed to grow wealth over the long term the way a diversified share fund aims to; its job is stability and income, not capital growth.

Whether a cash ETF, a savings account or a term deposit is the right home for your short-term money depends on how much you value liquidity, the government guarantee and simplicity, which ETFLens cannot weigh for you. If you are comparing income options more broadly, the bond ETFs and high-yield ETF guides cover funds that sit further along the risk spectrum, with higher potential income and, unlike AAA, real capital movement.

Who AAA may suit

ETFLens does not recommend funds. As a neutral, general description, a cash ETF like AAA may suit investors who want to hold cash inside their brokerage account with monthly income and same-day access, and who understand that it is not a bank deposit and does not carry the government deposit guarantee. It is unlikely to suit money intended to grow over the long term, where a diversified investment is the more common choice. Whether AAA suits you depends on your objectives, financial situation and needs, which ETFLens cannot assess.
