When building passive income from shares, I'm not chasing the highest dividend yields or the most aggressive payout forecasts. What I really want are reliable dividends, backed by businesses with long-term cash flows and a clear reason to remain relevant for decades.
That's why two ASX heavyweights stand out to me right now: Telstra Group Ltd (ASX: TLS) and Woolworths Group Ltd (ASX: WOW).
They operate in very different sectors, but they share the qualities I look for when buying shares for long-term income.
Telstra shares
Telstra plays an important role in Australia's digital economy. Mobile connectivity, internet access, and data services are no longer discretionary; they're essential for households, businesses, and government.
What makes Telstra attractive from an income perspective is the predictability of demand. People might delay big purchases during tough times, but they don't cancel their mobile plans or disconnect their internet. That creates a stable revenue base that supports dividends.
Telstra is also benefiting from a multi-year investment cycle in digital infrastructure. Data usage on its mobile network has more than tripled over the past five years, and there's no realistic future where demand for connectivity slows. As networks become more sophisticated, Telstra is shifting from simply selling bandwidth to selling higher-value services, such as prioritised connectivity, security, and enterprise solutions.
For income investors, that matters. Stable demand, combined with disciplined investment, increases the likelihood that dividends will remain sustainable, even if growth is modest. Telstra may not be exciting, but for passive income, I think boring can be beautiful.
Woolworths shares
If Telstra benefits from digital necessity, Woolworths benefits from something even more basic: people need to eat.
Supermarkets are among the most defensive businesses in the economy. Regardless of economic conditions, consumers still buy groceries every week. That makes Woolworths' revenue far less sensitive to economic cycles than most retailers.
Woolworths also operates on an enormous scale, serving around 24 million customers each week. Its supply chain strength, buying power, and brand trust enable it to navigate inflationary pressures and cost challenges more effectively than smaller competitors.
From an income perspective, this reliability is crucial. Woolworths isn't immune to short-term issues, as the past year has shown, but its underlying business model has proven durable over decades. That durability supports consistent dividend payments over time, even when growth is subdued. I believe this will remain the case over the next few decades.
Why these two work well together for income
What I like about pairing Telstra and Woolworths for passive income is how different their drivers are, yet how similar their outcomes can be.
Telstra is tied to data, connectivity, and digital infrastructure. Woolworths is tied to food, staples, and everyday consumption. Both sit at the centre of essential spending categories. Both generate steady cash flows. And both have business models that are unlikely to be disrupted overnight.
Neither share is about chasing rapid dividend growth. Instead, they're about dependability. The kind that allows investors to sleep at night while collecting income.
