Investing can sometimes feel complicated. With so many shares, funds, and strategies to choose from, it is easy to overthink things.

But building long-term wealth doesn't have to be complex.

In fact, with just three carefully chosen exchange-traded funds (ETFs), you could construct a portfolio that gives you global diversification, exposure to growth, and income potential — all in a simple, low-maintenance package.

Here's how it could look.

Vanguard Australian Shares Index ETF (ASX: VAS)

The Vanguard Australian Shares Index ETF provides investors with instant access to the 300 largest companies listed on the ASX. That includes household names like BHP Group Ltd (ASX: BHP), Commonwealth Bank of Australia (ASX: CBA), and CSL Ltd (ASX: CSL).

By owning the Vanguard Australian Shares Index ETF, you're essentially holding a slice of the Australian economy — including resources, banking, healthcare, and consumer staples. For many investors, it is the ultimate set and forget way to capture the performance of the local market. It also provides a reasonably attractive dividend yield.

iShares S&P 500 ETF (ASX: IVV)

While Australia offers plenty of strong ASX shares, it is still a small market compared to the United States. That's where the iShares S&P 500 ETF comes in, giving investors exposure to the 500 largest US-listed stocks.

The fund includes world-leading businesses like Apple (NASDAQ: AAPL), Microsoft (NASDAQ: MSFT), and Amazon (NASDAQ: AMZN), as well as defensive names like Walmart (NYSE: WMT) and Coca-Cola (NYSE: KO). With this ASX ETF, you are not just investing in the US economy, but also in many companies that dominate globally.

Betashares Global Cybersecurity ETF (ASX: HACK)

For a thematic kicker, the Betashares Global Cybersecurity ETF provides targeted exposure to one of the fastest-growing industries in the world: cybersecurity. As businesses and governments grapple with rising digital threats, demand for cybersecurity services is surging.

The ASX ETF's portfolio includes leaders like Palo Alto Networks (NASDAQ: PANW), CrowdStrike (NASDAQ: CRWD), and Fortinet (NASDAQ: FTNT). These are companies that are front and centre in the fight against cybercrime. By adding the Betashares Global Cybersecurity ETF, investors get a concentrated dose of innovation in a sector with powerful long-term tailwinds.

Foolish takeaway

By combining the Vanguard Australian Shares Index ETF, iShares S&P 500 ETF, and Betashares Global Cybersecurity ETF, you cover your bases: the Australian market, the world's largest economy, and a high-growth global theme in cybersecurity.

Together, these three ASX ETFs could form the backbone of a winning portfolio that is simple, diversified, and built for the long term — proving that sometimes, less really is more.
