Best platforms for ETF dollar-cost averaging in Australia
If you want to put $100-$1000 a month into ETFs and never think about it again, here are the platforms that make it work — and how much they actually cost over a year.
What is the cheapest way to buy ETFs every month in Australia?
If you are building wealth through index funds, dollar-cost averaging is the strategy most Australian financial advisers and the ASX itself recommend. You invest a fixed amount at regular intervals, buying more units when prices are low and fewer when they are high. Over time, it removes the stress of timing the market and enforces discipline.
The problem is that not every platform makes DCA easy or affordable. Some charge a flat brokerage fee that eats into small monthly contributions. Others lack automated investing entirely. This guide compares the platforms that offer proper auto-invest functionality, with a focus on what each one actually costs at $500/month and $1,000/month over a year.
Why DCA is the default Australian retail strategy
The ASX's own research shows that regular, consistent investing outperforms lump-sum timing for most retail investors, purely because it removes emotion. Combined with low-cost ETFs such as VAS, A200, or IVV, DCA lets you capture the market's long-term return without needing to pick entry points.
For this to work efficiently, three things matter: low or zero transaction costs, automated execution so you do not have to remember to buy, and CHESS sponsorship so you hold the underlying shares directly. The platforms below tick the auto-invest box. How they handle the other two varies significantly.
Platforms with proper auto-invest (TM-005)
Pearler: the DCA specialist
Pearler was built with DCA in mind. Its auto-invest feature goes beyond simple recurring buys: you can set up a portfolio allocation and have Pearler automatically rebalance toward it with each contribution. That is rare among Australian brokers.
Pearler charges $6.50 per ASX trade. At $500/month, that is $78 in brokerage over 12 months, or 1.3% of your total invested capital. At $1,000/month, the cost drops to 0.65% because the fixed fee is spread over a larger amount. Pearler is CHESS-sponsored (mixed model) and offers DRP, kids accounts, and SMSF accounts. If you plan to hold for decades, the ownership structure and rebalancing automation justify the fee.
Sharesies: fractional DCA with a fee twist
Sharesies lets you auto-invest across multiple assets, buying fractional ASX and US shares from $1. It uses a custodian model, meaning you do not hold shares directly on the CHESS registry. That is a trade-off for the ability to buy tiny slices of expensive ETFs.
Sharesies charges 1.9% per trade, capped at $6 for ASX. At $500/month, that cap means you pay $6 per month, or $72 per year (1.2% of capital). At $1,000/month, you still hit the $6 cap each month, so the cost is the same $72 (0.6% of capital). However, the monthly subscription plans complicate the picture. The $5/month plan covers $500 in auto-invest volume; the $10/month plan covers $3,000. If you already pay for a plan, the transaction fees are included. For a pure DCA strategy at $500/month, the $5 plan covers all your buys and costs $60/year, which is cheaper than the pay-as-you-go route.
CommSec Pocket: simple, bank-backed, CHESS-owned
CommSec Pocket is the simplest option for ASX ETFs. You choose from a curated list of ETFs (including IOZ, IVV, and IOO), set up auto-invest from $50, and your holdings are CHESS-sponsored. Trades cost $2 each.
At $500/month, that is $24 per year in brokerage (0.4% of capital). At $1,000/month, it is still $24 (0.12%). There is no platform fee, no inactivity fee, and DRP is available. The trade-off is the limited ETF selection and the lack of US shares or fractional investing. But for a pure ASX ETF DCA strategy, it is one of the cheapest CHESS-sponsored options available.
Note: CommSec Pocket is running a promotional $0 brokerage offer from 20 April 2026 to 17 July 2026. If your DCA timeline falls within that window, the cost drops to zero for three months.
Stake: recurring buys, but no auto-invest
Stake offers recurring buy functionality but does not qualify as a true auto-invest platform. You can set up a regular buy order for a specific ETF, but there is no portfolio-level automation or rebalancing. Stake charges $3 per ASX trade, making it $36/year at $500/month (0.6% of capital) or $36/year at $1,000/month (0.3%). It is CHESS-sponsored (mixed model) and offers US shares with fractional ownership. However, there is no DRP, no kids account, and no true DCA automation beyond simple recurring orders.
The free-DCA outliers
Two platforms deserve special mention because they change the cost equation entirely.
Vanguard Personal Investor charges $0 brokerage on all buys of Vanguard ETFs, including via auto-invest. You can set up a monthly purchase of VAS or VGS with zero transaction cost. The catch: Vanguard uses a custodian model, so your holdings are not on CHESS. There is also no DRP, and selling costs $9. At $500/month, you pay $0 in buy-side brokerage. At $1,000/month, also $0. Over a year, that saves you $24 to $78 compared to the cheapest alternatives. Vanguard also offers kids accounts and SMSF accounts.
Webull offers free ETF trades (though Webull was not in the detailed platform data set, its zero-brokerage ETF offering is well documented in the Australian market). For a pure DCA strategy into a single ETF, free brokerage is hard to beat.
Decision framework
Choose based on your priorities.
If CHESS ownership matters most and you want the lowest cost for ASX ETFs: go with CommSec Pocket. At $2 per trade with auto-invest from $50, it is the cheapest CHESS-sponsored DCA option for ASX ETFs. The limited ETF selection is the main constraint.
If you want portfolio-level automation and rebalancing: Pearler is the only platform that rebalances your allocation automatically with each contribution. The $6.50 fee is worth it if you manage a multi-ETF portfolio.
If you want to invest tiny amounts into US ETFs: Sharesies fractional model lets you DCA into US ETFs from $1. The custodian model and subscription fees are the trade-offs.
If you want zero-cost DCA into Vanguard ETFs: Vanguard Personal Investor is the clear winner. No buy-side brokerage, no platform fee, and auto-invest that handles multiple assets. Just be comfortable with the custodian model and the lack of DRP.
Minimum trade amounts: CommSec Pocket starts at $50. Vanguard Personal Investor starts at $200. Pearler has no minimum trade amount beyond the brokerage fee. Sharesies has no minimum.
Kids accounts: Pearler, Sharesies, and Vanguard Personal Investor all offer kids accounts. CommSec Pocket and Stake do not.
DRP availability: Pearler, CommSec Pocket, and Sharesies support dividend reinvestment. Vanguard Personal Investor and Stake do not.
