For investors approaching retirement, the focus often shifts from growth to income, stability, and capital preservation.
The goal is simple: build a portfolio that can generate reliable dividends across different economic cycles while still offering some protection against inflation and long-term change.
Here are four ASX shares that could help deliver decades of income.

Telstra Group Ltd (ASX: TLS)
Telstra is one of Australia's most defensive income stocks and perfect for a retirement portfolio.
As the country's largest telecommunications provider, Telstra benefits from essential services demand. Mobile, internet, and data usage are deeply embedded in everyday life, helping support steady recurring revenue.
One of Telstra's key strengths is its improved balance sheet and focus on infrastructure-led growth through its mobile network and enterprise services. This provides a foundation for relatively stable dividend payments over time.
The main limitation is modest growth, as the mature telecom market restricts earnings expansion. However, for retirees, Telstra's defensive profile and income reliability make it a core portfolio candidate.
APA Group (ASX: APA)
This $14 billion ASX stock offers exposure to critical energy infrastructure.
The company owns and operates gas pipelines and energy assets across Australia, generating regulated and long-term contracted revenue streams. This provides a high level of earnings visibility, which is ideal for income-focused investors.
APA's growth strategy includes expanding its renewable energy and electricity transmission capabilities, positioning it for a gradual transition in the energy sector.
However, regulatory risk and the long-term shift away from gas remain key considerations. Despite this, APA's predictable cash flows have historically supported consistent distributions. An important characteristic for retirement.
Wesfarmers Ltd (ASX: WES)
Wesfarmers is a diversified powerhouse that blends income with quality growth.
Its portfolio includes Bunnings, Kmart, Officeworks, and other retail and industrial businesses. These operations generate strong cash flow, supporting reliable dividends while also allowing reinvestment for future growth.
Bunnings in particular provides a defensive earnings base, while Kmart has proven its ability to thrive in value-driven retail environments.
The trade-off is valuation risk, as Wesfarmers currently trades at a premium due to its high-quality businesses. Still, its track record of disciplined capital management makes it a strong long-term income holding.
BHP Group Ltd (ASX: BHP)
This ASX giant adds a global resource and dividend engine to the retirement portfolio.
As one of the world's largest diversified miners, BHP benefits from exposure to iron ore, copper, and other key commodities. Its scale, low-cost operations, and strong balance sheet support substantial dividend payments over time.
BHP also offers indirect exposure to long-term global trends such as electrification and infrastructure development, particularly through its copper assets.
The main risk is commodity price volatility, which can significantly impact earnings and dividends from year to year.
Building a retirement income portfolio
Together, Telstra, APA Group, Wesfarmers, and BHP offer a diversified mix of defensive income, infrastructure stability, quality retail earnings, and global resource exposure.
While each carries its own risks, combining them can help smooth income over time and provide retirees with a balance of yield, reliability, and long-term resilience.
