If you're looking for high-growth ASX shares to buy in 2025, you're in luck. The Australian market is home to several exciting companies with strong long-term prospects.

Right now, leading brokers have identified a few shares that could offer plenty of upside thanks to structural tailwinds and expanding market opportunities. Here are three ASX growth shares that could be worth considering:

Megaport Ltd (ASX: MP1)

Cloud computing and artificial intelligence (AI) are driving a surge in data usage, and Megaport is positioned to capitalise on this megatrend.

Megaport operates a global cloud connectivity network, allowing businesses to create secure, scalable, and agile connections in just a few clicks. The company partners with global service providers, data centre operators, and managed service companies, with a presence in almost 1,000 locations worldwide.

Analysts at Morgans are particularly bullish on Megaport, believing it is uniquely placed to benefit from increasing data movement. The broker commented:

Megaport is a global cloud connection network and the leading Network as a Service provider. It operates the largest data centre connection business in the world, connecting to 850 data centres through a fully automated, on-demand telco network. We think it is uniquely placed to help business move data globally and benefit from the growth of data related to both cloud computing and AI.

Morgans has an add rating and $14.00 price target on Megaport shares.

Web Travel Group Ltd (ASX: WEB)

Another ASX growth stock that analysts like right now is Web Travel Group. It is a travel technology company that operates a business-to-business (B2B) marketplace, connecting hotels and other travel sellers with buyers worldwide.

Goldman Sachs is bullish about Web Travel Group's long-term potential and believes recent share price weakness has created an attractive buying opportunity. The broker highlighted the company's dominant market position, commenting:

WEB is the second largest Hotel Bed wholesaler globally with <10% of the global hotel wholesale market. We are Buy rated on WEB as we have confidence that WEB will be able to grow TTV in line with its FY25/30 targets of A$5bn/A$10bn respectively. In particular, we believe WEB is well placed to continue to grow in key US/APAC growth markets, though expect revenue margin to lower towards ~6.3% over time as the company expands into lower margin US/APAC markets. WEB is trading below fair value, on our estimates.

Goldman has a buy rating and $7.00 price target on its shares. This suggests that upside of almost 40% is possible for investors.

Xero Ltd (ASX: XRO)

Finally, cloud accounting leader Xero is another ASX growth share that could be a great pick in 2025.

The company serves 4.2 million subscribers globally and has a huge total addressable market (TAM), estimated at over 100 million small-to-medium-sized businesses.

Goldman Sachs is bullish on Xero's expanding product suite and growing market penetration. The broker is particularly positive on its outlook for 2025, commenting:

We are positive on the CY25 outlook as given that accelerating product cadence is supporting subscriber and ARPU growth in ANZ and abroad. However, we expect a step-up in US investment this year, presenting risk to consensus margins – but are increasingly positive on this opportunity.

Goldman has a buy rating on Xero and a $201.00 price target. This implies potential upside of 13% for investors.
