Building a portfolio for retirement income isn't just about finding the highest dividend yields. The goal is to create a reliable stream of income that can continue growing over time, while also preserving capital through different market cycles.
That's why I prefer a mix of high-quality companies and diversified exchange-traded funds (ETFs). Together, they can provide exposure to different sectors, geographies and income sources, reducing the reliance on any single investment.
If I were building a portfolio for retirement income today, these five ASX investments would be at the top of my list.

BHP Group Ltd (ASX: BHP)
When it comes to retirement income, BHP offers something few companies can match: ownership of some of the world's lowest-cost mining assets.
The mining giant generates enormous cash flows from iron ore, copper and metallurgical coal, allowing it to return significant amounts of capital to shareholders through dividends over the long term.
While earnings and dividends will naturally fluctuate with commodity prices, BHP's strong balance sheet, operational scale and diversified resource base make it one of the most dependable dividend payers on the ASX.
The growing importance of copper in electrification and renewable energy also provides an attractive long-term growth opportunity alongside its income appeal.
Commonwealth Bank of Australia (ASX: CBA)
No retirement income portfolio feels complete without exposure to Australia's biggest bank.
Commonwealth Bank has built an enviable record of generating consistent profits through economic cycles, supported by its dominant position in home lending, deposits and business banking.
Although the shares rarely look cheap, investors aren't simply paying for today's earnings. They're buying a business with outstanding profitability, a powerful brand and a history of delivering fully franked dividends.
For retirees seeking dependable income, CBA continues to earn its place.
Transurban Group Ltd (ASX: TCL)
Infrastructure can add another layer of stability to retirement income, and that's exactly where Transurban shines.
The company owns and operates many of Australia's busiest toll roads, generating recurring cash flows from assets that are extremely difficult to replicate. As cities continue growing and traffic volumes increase over time, Transurban benefits from both rising usage and inflation-linked toll increases across many of its concessions.
That combination has supported a long history of attractive distributions.
Vanguard Australian Shares High Yield ETF (ASX: VHY)
No single company should determine the success of a retirement income portfolio. That's why I'd include the Vanguard Australian Shares High Yield ETF.
VHY provides exposure to dozens of Australia's highest-yielding dividend-paying companies across sectors including banking, resources, healthcare, telecommunications and consumer staples. Instead of relying on one dividend stream, investors receive income from a broad collection of established Australian businesses.
That diversification helps smooth income over time while reducing stock-specific risk.
Vanguard MSCI Index International Shares ETF (ASX: VGS)
While VGS isn't known for delivering a high dividend yield, I still believe it plays an important role in generating retirement income.
The ETF invests in hundreds of leading companies across developed markets, including many of the world's largest technology, healthcare and consumer businesses. Those companies may pay lower dividends today, but they also offer significant earnings and capital growth potential.
Over a long retirement, that growth can help offset inflation, increase portfolio value and support rising future income through capital appreciation or selective withdrawals.
