I believe that one of the simplest and most effective ways of building wealth in the share market is through buy and hold investing.

Instead of trying to time the market or jump in and out of stocks, long-term investors focus on owning high-quality Australian stocks that can compound returns over time.

Warren Buffett, one of the greatest investors of all time, has long championed this strategy. His philosophy is simple, he said:

If you aren't willing to own a stock for ten years, don't even think about owning it for ten minutes.

Buying and holding Australian stocks

The idea is that by focusing on fundamentally strong companies with sustainable competitive advantages, investors can ride out short-term volatility and benefit from the power of compounding over time.

Investing for the long term also reduces the risk of making costly mistakes driven by emotions. Market downturns, earnings misses, or short-term headwinds can scare investors into selling at the worst possible time. But for those who stay the course, history has shown that quality companies tend to recover and continue growing.

With this in mind, here are three Australian stocks that could be excellent buy and hold investments until 2030:

CSL Ltd (ASX: CSL)

CSL is one of the world's leading biotechnology companies, specialising in blood plasma therapies, nephrology, and vaccines. The company has an incredible track record of growth, driven by its investment in R&D and global expansion. Overall, CSL's ability to innovate and its strong pricing power make it a defensive, high-quality stock that could continue compounding returns for years to come.

Bell Potter currently has a buy rating and $345.00 price target on its shares.

Life360 Inc. (ASX: 360)

Another Australian stock to look at is Life360. It is a growing tech company that provides family safety and location tracking services through its hugely popular mobile app. With tens of millions of active users and a growing paid subscription base, the company is scaling rapidly. And as digital safety becomes a bigger priority for families, Life360 could continue to grow into a major player in the tech sector.

Bell Potter has a buy rating and $27.75 price target on Life360's shares.

WiseTech Global Ltd (ASX: WTC)

WiseTech is a global leader in logistics software, providing essential supply chain solutions to some of the biggest freight forwarders in the world. Its flagship product, CargoWise, is used across over 180 countries, and the company continues to expand its global footprint. With the digitisation of logistics still in its early stages, WiseTech has plenty of runway for growth.

Morgan Stanley has an overweight rating and $160.00 price target on its shares.
