Warren Buffett is widely regarded as one of the greatest investors of all time and following in his footsteps is highly recommended.
But if you are investing on the ASX, there is one obvious challenge. Buffett does not invest here, and we do not know which Australian shares he would choose.
That said, we do know how he thinks.
And that gives us a useful framework for building a Buffett-inspired portfolio using ASX shares.

Strong competitive advantages
One of Buffett's core principles is investing in companies with durable competitive advantages, often referred to as economic moats.
These are businesses that are difficult for competitors to replicate. This might be due to brand strength, scale, intellectual property, or deep integration into customer operations.
On the ASX, examples could include companies like CSL Ltd (ASX: CSL), which benefits from its global scale and complex plasma network, or REA Group Ltd (ASX: REA), which dominates online real estate listings in Australia.
These types of businesses are often able to maintain pricing power and deliver consistent returns over time.
Look for consistent earnings and strong returns
Warren Buffett has always preferred companies that generate reliable profits.
Rather than chasing speculative growth, he looks for businesses that can steadily grow earnings year after year. High returns on capital and strong cash flow are often key indicators.
ASX companies like Cochlear Ltd (ASX: COH) and ResMed Inc (ASX: RMD) fit this mould, with established products, global demand, and recurring revenue streams.
The goal is to own businesses that perform well across different economic conditions.
Keep it simple and understandable
Another hallmark of Buffett's approach is simplicity.
He invests in businesses he understands. This often means avoiding overly complex or speculative industries.
For ASX investors, this could translate to focusing on companies with clear business models and predictable revenue streams.
Retailers, healthcare companies, and infrastructure businesses can often be easier to understand than highly speculative sectors.
This might mean Woolworths Group Ltd (ASX: WOW), APA Group (ASX: APA), and Wesfarmers Ltd (ASX: WES).
Think long term
Warren Buffett is famous for his long-term mindset.
He has often said his favourite holding period is "forever." This reflects his belief in owning great businesses and allowing compounding to do the work.
A Buffett-inspired ASX share portfolio should be built with a similar mindset. Instead of reacting to short-term market movements, the focus should be on holding quality companies for many years.
Avoid overpaying
Even the best business is not a good investment at the wrong price.
Buffett looks for opportunities to buy high-quality companies at reasonable valuations. This often means being patient and waiting for periods of market weakness.
For ASX share investors, this could involve building a watchlist and being ready to act when quality shares fall out of favour.
Foolish takeaway
We may never know exactly which ASX shares Buffett would buy.
But by focusing on competitive advantages, consistent earnings, simplicity, and long-term thinking, investors can build a portfolio that reflects his philosophy.
It is about applying the principles that made him successful to our own portfolios.
