Building a diversified portfolio from zero doesn't need complexity, clever trading, or a spreadsheet that looks like a NASA launch plan. With five well-chosen ETFs, investors can spread their money across Australia, the world's biggest companies, bonds, and cash.
The backbone of any ETF portfolio is broad market exposure. A total world or developed markets ETFs give you instant access to thousands of companies across countries and sectors.
This portfolio leans on a 30% Australian base, around 35% global equities, and a stabilising mix of bonds and cash. It's designed to be boring in the best possible way.

Australian backbone
Every portfolio needs a strong local anchor, and ETFs like BetaShares Australia 200 ETF (ASX: A200) or Vanguard Australian Shares Index ETF (ASX: VAS) will do the heavy lifting. Tracking the top 200 companies on the ASX, they give instant exposure to the pillars of the Australian market: Commonwealth Bank of Australia (ASX: CBA), BHP Group Ltd (ASX: BHP), CSL Ltd (ASX: CSL), National Australia Bank Ltd (ASX: NAB), Westpac Banking Corp (ASX: WBC), and Wesfarmers Ltd (ASX: WES).
Banks, miners, and healthcare dominate, delivering dividends and a familiar economic link to home. At roughly 30% of a portfolio, this ETF provides stability and income without stock-picking risk.
Global heavyweights
For broad offshore exposure, iShares Global 100 ETF (ASX: IOO) owns the biggest corporate names on the planet. This ETF holds around 100 global giants, including Apple, Microsoft, Amazon, and Alphabet.
The US leads the weighting, but Europe and Japan feature strongly, giving investors exposure to multiple economies through companies with global revenue streams. IOO forms the backbone of global equity exposure without overcomplicating things.
Growth kicker
While iShares Global 100 covers the world's blue chips, BetaShares NASDAQ 100 ETF (ASX: NDQ) adds growth firepower. Tracking the NASDAQ-100 Index (NASDAQ: NDX), it is packed with technology and innovation leaders such as Nvidia, Apple, Microsoft, Meta and Alphabet.
This tech ETF is more volatile, but it has historically driven returns during periods of strong global growth. A modest allocation helps tilt the portfolio toward the future without dominating it.
Liquidity and safety
Cash is unfashionable until markets fall apart. When share markets wobble, bonds often soften the blow, providing income and stability. This ETF acts as the portfolio's shock absorber rather than a return engine.
iShares Core Composite Bond ETF (ASX: IAF) invests in high-interest bank deposits, offering capital stability and ready liquidity. It won't deliver fireworks, but it provides flexibility, whether for opportunities, expenses, or peace of mind.
Put together, these five ETFs or equivalent funds create a low-cost, diversified, easy-to-manage portfolio that spans Australian shares, global leaders, growth stocks, bonds, and cash. No guessing, just broad exposure built for the long haul.
