Building long-term wealth on the share market doesn't require constant trading or chasing the latest trend.
In many cases, it comes down to identifying high-quality businesses with lasting advantages and holding them as they grow over time.
With that in mind, here are three ASX 300 shares that could be worth considering for the next decade.

Breville Group Ltd (ASX: BRG)
Breville has quietly built one of the most impressive global consumer brands to come out of Australia.
At the centre of its success is coffee, and more specifically, its premium at-home coffee machines. As more consumers look to recreate cafe-quality coffee in their own kitchens, Breville has been a major beneficiary of this shift.
This isn't just a short-term trend either. The company's half-year results in February showed that coffee continues to be a key growth driver, with strong double-digit growth helping push revenue to a record $1.1 billion for the half.
What makes Breville particularly attractive is how it has turned a simple appliance into an ecosystem. From machines to grinders and even its Beanz coffee subscription platform, it is embedding itself deeper into the daily routines of its customers.
Combined with global expansion into markets like China, Korea, and the Middle East, Breville appears to have a long runway for growth.
REA Group Ltd (ASX: REA)
Another ASX 300 share that could be worth considering as a buy and hold investment is REA Group.
As the owner of realestate.com.au, it holds a leading position in Australian property listings, which is a market where scale and network effects are incredibly difficult to disrupt.
Even during periods of softer housing activity, REA has shown an ability to grow earnings through pricing power and premium products for agents. Over time, this combination of market leadership and monetisation strength has underpinned consistent and robust earnings growth.
Looking ahead, its expansion into adjacent services such as data, financing, and developer tools provides additional avenues for growth beyond simple listings.
For a long-term investor, REA Group offers exposure to a high-quality digital marketplace with strong competitive advantages and a track record of execution.
Temple & Webster Group Ltd (ASX: TPW)
A third ASX 300 share that could be a top buy and hold option is Temple & Webster.
It has established itself as a leading online-only furniture and homewares retailer in Australia. While the category has historically been dominated by physical stores, consumer behaviour is gradually shifting.
Temple & Webster's asset-light model gives it flexibility that traditional retailers often lack. It can scale its product range quickly, respond to trends, and operate without the cost burden of a large store network.
Although earnings can be more cyclical due to housing and consumer spending trends, the long-term direction of travel appears favourable. As online penetration in furniture continues to increase, Temple & Webster is well positioned to capture a growing share of the market.
