If you've got $5,000 ready to invest, the ASX offers plenty of opportunities to buy high-quality shares that could deliver strong returns over the long term.

While the market can be unpredictable in the short run, owning businesses with strong competitive positions, big addressable markets, and solid execution can tilt the odds in your favour.

Here are three Australian stocks that analysts think could be worth a close look right now.

REA Group Ltd (ASX: REA)

The first Australian stock that could be a buy is REA Group. It is Australia's leading online real estate listings company, operating the country's dominant property platform, realestate.com.au. Its network effects are enormous — more listings attract more buyers, which attracts more agents, creating a powerful cycle that is hard for competitors to break.

And with its platform continuing to dominate and interest rates heading lower, REA Group looks well-placed to continue to strong growth over the remainder of the decade.

Morgan Stanley is bullish on the company and has an overweight rating and $300.00 price target on its shares.

Telix Pharmaceuticals Ltd (ASX: TLX)

Another Australian stock that could be a buy with $5,000 is Telix Pharmaceuticals. It is a fast-growing biotech specialising in radiopharmaceuticals. These are targeted radiation treatments used for diagnosing and treating cancer. Its lead product, Illuccix, has been approved in multiple major markets for the detection of prostate cancer and is already generating significant revenue.

The company is working on expanding Illuccix's applications while advancing a deep pipeline of other targeted therapies. If Telix can successfully commercialise more of its pipeline, the long-term potential could be substantial.

It is partly for this reason that Bell Potter has a buy rating and $33.00 price target on its shares.

Temple & Webster Group Ltd (ASX: TPW)

Finally, Temple & Webster could be a top Australian stock to buy now. It is Australia's largest online-only furniture and homewares retailer. Its asset-light model allows it to offer a vast product range without the overhead costs of physical stores.

The company has been growing strongly as more Australians embrace online shopping for home goods. It continues to expand its private label range, invest in technology, and improve delivery times — all of which help strengthen customer loyalty.

And with the shift to online shopping still in its early days in the furniture and homewares category, Temple & Webster has a long runway for growth over the next decade.

Morgan Stanley is also a fan of Temple & Webster and has an overweight rating and $28.00 price target on its shares.
