When it comes to ASX telco stocks, Telstra Corporation Ltd (ASX: TLS) is often the cautious investor's pick. It's large, familiar and pays a reliable dividend. But size and stability don't always deliver the best value.
Aussie Broadband Ltd (ASX: ABB) is a smaller and more speculative investment, but I think what it lacks in size, it makes up for in potential.
So, which is the better investment?

Telstra: A reliable investment with limited room for growth
Let me couch what I am about to say – Telstra is, by almost all metrics, a high-quality business and a relatively safe bet. It dominates the Australian telecommunications market, owns critical infrastructure, generates strong cash flows, and offers an attractive, fully franked dividend. All of this stability makes it a highly dependable investment.
But where it lacks appeal for me is growth potential. Telstra's core markets are mature. And while its management has shown a disciplined approach to cost control, revenue growth from ordinary activities remains on the modest side – 0.9% uplift in FY25 on the prior corresponding period. That's not necessarily a deal breaker in and of itself, but it does limit the potential upside for investors.
At current prices, you're paying for stability and income certainty rather than earnings growth. If you're a defensive investor, it's going to win hands down. For growth investors, I think there's more value to be had elsewhere in the sector.
Aussie Broadband: Strong fundamentals and well positioned to grow
Aussie Broadband plays in the same markets as Telstra. But unlike Telstra, which is defending an established base, Aussie Broadband is carving new pathways for itself, particularly in government and corporate contracts. These contracts tend to offer good margins and customer stickiness, positioning Aussie Broadband for accelerated growth. In FY25, it saw an 18.7% revenue uplift to $1.19 billion.
And as it scales its customer base, its operating leverage has room to grow. Fixed networks and systems will spread across a growing revenue base, allowing margins to expand. Telstra, on the other hand, may have already exhausted much of this margin expansion potential.
But it is important to note that risks can be heightened for a smaller player like Aussie Broadband. Across the telco sector, competition is fierce, and pricing pressure can be intense. Of course, these risks still apply to Telstra. However, as a well-established player with significant brand equity and scale, they are less likely to bother investors in any meaningful way.
That said, Aussie Broadband doesn't carry the legacy cost base of its much bigger competitor. And its disciplined approach to growth, prioritising return on invested capital rather than expansion at all costs, adds to its appeal for me.
The bottom line
Both are solid telco stocks, so you probably can't go wrong. If your strategy is defensive, then Telstra remains the safest bet. But if you are looking for exposure to earnings growth and are comfortable with some share price volatility, Aussie Broadband is my pick. At current prices, I think it's an opportunity to get in on a quality business that has the hallmarks of further impressive growth to come.
