When I think about dividend investing over a long period like seven years, I am looking for businesses that can grow their distributions over time, supported by reliable cash flow, strong assets, and structural demand.
For me, that often leads back to infrastructure.
These are not flashy businesses. But they are ASX dividend shares that tend to provide exactly what long-term income investors need. Stability, visibility, and the potential for steady growth.

Transurban Group (ASX: TCL)
Transurban is one of those businesses that I think becomes more attractive the longer your time horizon is.
At its core, it owns and operates toll roads across Australia and North America. These are essential assets that people use every day, often without much thought.
Traffic continues to grow steadily, with average daily trips rising and supporting revenue growth across the network. At the same time, toll revenue and EBITDA are also moving higher, reflecting both usage and pricing power.
What I like most is the predictability.
Transurban expects a FY26 distribution of 69 cents per security, representing growth on the prior year and an attractive forward dividend yield of 4.9%. That kind of steady increase is exactly what I want from an income investment.
On top of that, its assets have very long concession lives. In some cases, decades. That gives the company a long runway to generate cash flow and continue returning it to investors.
Overall, I see this as a core income holding that could quietly compound over time.
APA Group (ASX: APA)
APA Group offers a different type of infrastructure exposure, but I think it complements Transurban well.
Instead of toll roads, APA owns and operates energy infrastructure, including gas pipelines, electricity transmission assets, and renewable energy projects.
These are critical assets for the Australian economy.
What stands out to me is how stable the earnings base is. A large portion of APA's revenue is linked to long-term contracts and inflation-linked tariffs, which helps support consistent cash flow.
That is showing up in the numbers. APA delivered growth in revenue and earnings in its recent half, with underlying EBITDA rising 7.6%. Importantly for income investors, distributions are also moving higher, with FY26 guidance of 58 cents per security. At a current share price of $9.87 per share, this equates to an above-average distribution yield of 5.9%.
Looking ahead, I believe this distribution can continue to grow due to its clear growth pipeline. Management recently increased its organic growth pipeline to around $3 billion, which should help drive future earnings and, in turn, distributions.
Overall, I think APA offers a compelling mix of income today and growth over time.
Foolish takeaway
If I were building an income-focused portfolio for the next seven years, I think Transurban and APA Group would be great picks.
Transurban brings exposure to essential transport infrastructure with long concession lives and steadily rising distributions. APA Group provides access to energy infrastructure with contracted, inflation-linked revenue and a visible growth pipeline.
