ASX blue-chip shares are typically some of Australia's biggest companies. Some of them do not have a lot of growth potential because they're mature businesses with few avenues to accelerate earnings noticeably.
I think one of the main appeals of good blue chips is that they're large and can deliver earnings growth.
The three businesses I want to tell you about are three of the strongest Australian companies that can grow at a pleasing pace.

Telstra Group Ltd (ASX: TLS)
Telstra is Australia's leading telecommunications business, with the most subscribers and the widest network coverage.
Australia is becoming an increasingly digital country, and this is helping grow the importance of a 5G mobile connection. Telstra's total subscriber numbers continue rising, and the average revenue per user (ARPU) is growing thanks to price increases.
I expect the company's mobile revenue and operating profit (EBITDA) to increase in the coming years, which is the key division.
A bonus earnings boost could be the adoption of wireless broadband by households and small businesses – that's where a broadband connection is powered by 5G rather than the NBN cables. These connections could be significantly more profitable for Telstra than a connection through the NBN.
Pleasingly, the ASX blue-chip share has grown its annual payout in recent years and currently has a grossed-up dividend yield of 5.5%, including franking credits.
Wesfarmers Ltd (ASX: WES)
Wesfarmers is one of Australia's largest retailers with a number of businesses, including Bunnings, Kmart, Officeworks, Target, and Priceline. WesCEF (chemicals, energy and fertilisers), healthcare businesses, and an industrial and safety division make up most of the rest of the business.
The company's focus on providing customers with great value has led to Kmart and Bunnings achieving a strong market position in their respective retail sectors. Their scale means they're able to achieve strong profit margins.
I like the efforts of the company to diversify its earnings, such as creating a healthcare division which now includes Priceline, Clear Skincare, SILK Group (laser clinics), Soul Pattinson Chemist, InstantScripts, and SiSU Health. The company is also working on a lithium mining project.
With ongoing business diversification and Kmart looking to sell more Anko products to international markets (such as North America and the Philippines), I think there is still a lot more growth ahead for this ASX blue-chip share.
Macquarie Group Ltd (ASX: MQG)
Macquarie is one of the largest ASX financial shares, and I think it has the ability to significantly scale in the coming years. It has more earnings diversification than the big four banks, with multiple divisions (beyond just banking) that generate a majority of Macquarie's income internationally.
It has an asset management division, a local banking segment, investment banking, and a commodities and global markets (CGM) division. It has multiple areas that it can allocate money to generate growth.
Macquarie is rapidly growing its market share in Australia's banking industry. In the FY26 first-half result, its home loan portfolio reached $160.3 billion, up 13% compared to 31 March 2025. That's an incredible rise in six months – it has now reached a market share of 6.5%. Banking deposits rose by 12% to $192.5 billion.
Its banking strategies are clearly working because it has a net promoter score (NPS) – customer satisfaction – that's "significantly above major bank peers".
I think the ASX blue-chip share has a promising future.
