Our data
How we source and verify ETF data
Every number on ETFLens comes from a primary source document. Here is exactly where the data comes from, how often it is checked, and what we do when something does not match.
Primary sources
ETFLens sources data directly from fund manager disclosure documents. For each of the 100ETFs in the database, the primary sources are the fund manager's published Product Disclosure Statement (PDS), quarterly factsheet, and for BetaShares ETFs, the live holdings CSV files published at betashares.com.au. ETFLens does not use data aggregators or third-party data feeds. Every data point traces back to a document published by the fund manager. The fund managers currently covered are Vanguard Australia, BetaShares, iShares (BlackRock Australia), VanEck Australia, Global X ETFs Australia, and SPDR (State Street Global Advisors Australia).
Quarterly validation scanner
ETFLens runs an automated Python scanner against fund manager factsheets and holdings CSVs each quarter. The scanner checks 100 ETFs across the following fields: management expense ratio (MER), dividend yield, top 10 holdings by name and weight, sector exposure percentages, geographic exposure percentages, and fund size (AUM). Each field is compared against the live primary source document. Mismatches are flagged for review and resolved before the data update is published. As at Q2 2026, the scanner validates over 600 data points across 100 ETFs. No data update ships without a completed scanner run.
Update schedule
ETF data is updated quarterly, aligned with the fund manager factsheet publication cycle. Most Australian ETF managers publish updated factsheets within 30 days of each quarter end (March, June, September, December). The current data is as at Q2 2026, updated May 2026. Holdings data changes most frequently. BetaShares publishes live holdings CSVs daily and ETFLens updates top holdings from these each quarter. MER changes are uncommon but the scanner is specifically designed to detect them between quarterly updates.
Known limitations
ETFLens data is updated quarterly, not in real time. Between quarterly updates, fund holdings, fees, and distributions may change without being reflected on this site. The data as-of date shown on each ETF page indicates when that ETF's data was last verified against a primary source document.
Holding weights for Vanguard ETFs use descending placeholder values because Vanguard Australia does not publish individual holding weights in its factsheets. Holding names are verified from factsheets. Weights are approximations only and are noted as unverified in the underlying data.
Overlap calculations are based on top holdings data only. Two ETFs may share more underlying exposure than the overlap checker shows if the shared exposure falls outside the top holdings published by each fund manager.
This site does not display live prices, NAV, or intraday data. All figures are sourced from the most recent quarterly factsheet unless otherwise noted. General information only, not financial advice.
