Technology stocks have emerged as one of the most exciting and dynamic sectors on the Australian Securities Exchange (ASX). After years of volatility, 2025 has brought renewed strength to the tech sector, with earnings upgrades, strategic acquisitions, and macroeconomic tailwinds boosting confidence. The question on many investors’ minds is simple: which ASX tech stocks are worth buying now in September 2025?
What Are Tech Stocks?
At their core, tech stocks represent businesses that derive most of their value from technology, whether that’s software, cloud services, artificial intelligence, or digital infrastructure. Unlike traditional sectors such as banking or mining, tech companies often prioritise rapid growth, global scalability, and recurring revenue streams.
The ASX is sometimes viewed as a resources-heavy exchange, dominated by iron ore, gold, and energy producers. Yet in recent years, technology has carved out a significant place on the bourse. Companies like Xero (ASX: XRO), WiseTech Global (ASX: WTC), and NEXTDC (ASX: NXT) are now regarded as household names, each with a market capitalisation in the billions of dollars and international operations spanning multiple continents. Investors must remember that “tech” on the ASX is broad. It includes Software-as-a-Service (SaaS) platforms, cloud computing specialists, fintechs, e-commerce platforms, cybersecurity providers, and even artificial intelligence developers. These sub-sectors are highly diverse but share one common trait: they are all shaping the digital economy.
Why Invest In ASX Tech Stocks?
The appeal of ASX tech stocks lies in their growth profile. While mining and banking remain cyclical, tech stocks benefit from secular megatrends such as digitisation, automation, and artificial intelligence. These forces are not going away; in fact, they are intensifying.
Market performance figures for FY2025 show that the S&P/ASX 200 recorded strong gains, with technology and banking playing a significant role, although exact growth percentages vary depending on the source. WiseTech Global, Xero, and NEXTDC were standout performers, highlighting that even in a cautious earnings environment, tech can still deliver. For example, TechnologyOne (ASX: TNE), a mid-cap SaaS provider, announced double-digit recurring revenue growth in its 2025 half-year results, a testament to the resilience of software platforms.
Another reason to consider ASX tech stocks now is the macroeconomic backdrop. Economic indicators in 2025 suggest inflation is trending lower, and the Reserve Bank of Australia has hinted at a more accommodative stance, though exact figures remain subject to market updates. When rates fall, investors often flock back into tech, as discounted cash flow models suddenly look more attractive.

Types Of Tech Stocks ASX
When investors talk about technology on the ASX, it’s easy to assume it’s a single, uniform sector. In reality, the landscape is highly diverse, covering multiple categories that serve very different markets and growth drivers. Understanding these types is essential before making investment decisions.
1. Software-as-a-Service (SaaS)
This is one of the most prominent areas of ASX tech. Companies such as Xero (ASX: XRO) and TechnologyOne (ASX: TNE) provide subscription-based platforms that customers pay for regularly. SaaS firms benefit from high retention rates and predictable revenues, which investors value in volatile markets. Because their products are essential to small businesses, government departments, or large corporations, these companies often achieve sticky adoption and strong margins.
2. Digital Infrastructure
Australia’s increasing demand for cloud storage, artificial intelligence, and secure networks has created opportunities for firms like NEXTDC (ASX: NXT), Megaport (ASX: MP1), and Macquarie Technology Group (ASX: MAQ). These businesses own and operate world-class data centres, interconnection platforms, and cloud hosting services. As AI workloads surge, their facilities are becoming mission-critical, making this one of the fastest-growing sub-sectors of tech on the ASX.
3. Fintech
Financial technology is another significant category. Companies like Block Inc. (ASX: SQ2), owner of Afterpay, Zip Co (ASX: ZIP) and EML Payments (ASX: EML) are transforming how consumers and businesses make payments, access credit, and manage transactions. While these businesses can be volatile due to regulatory scrutiny and competition, they offer investors exposure to long-term shifts in digital finance.
4. Emerging and Frontier Tech
For investors willing to take on more risk, the ASX is also home to speculative innovators. BrainChip (ASX: BRN), which develops neuromorphic AI chips, and Spacetalk (ASX: SPA), which builds wearable safety devices, fall into this category. These companies are early-stage and may not yet be profitable, but they operate in cutting-edge fields with high potential upside if their products gain widespread adoption.
5. E-commerce and Digital Platforms
Beyond software and infrastructure, the ASX also features digital-first companies like REA Group (ASX: REA) in property listings and Temple & Webster (ASX: TPW) in online furniture retailing. These businesses rely on digital platforms to capture consumer demand, and their scalability often comes from strong network effects.
3 Best ASX Tech Stocks to Buy in September 2025
Xero (ASX: XRO)
Xero (ASX: XRO) remains one of the most trusted and widely followed technology companies among Australian investors. Known for its cloud-based accounting software, it supports millions of small and medium-sized businesses worldwide. The company’s ability to expand across geographies, particularly the UK and North America, has given it global scale, while its SaaS model ensures sticky, recurring revenues.
NEXTDC (ASX: NXT)
As data becomes the foundation of the digital economy, NEXTDC (ASX: NXT) is positioned at the centre of this trend. The company currently operates 13 state-of-the-art data centres across Australia, with several more under development in Sydney, Melbourne, and Brisbane. Its facilities are NVIDIA DGX-Ready certified, enabling them to support advanced AI workloads, a critical growth driver as enterprises and governments accelerate AI adoption.

3 Best ASX Tech Stocks to Buy in September 2025
Xero (ASX: XRO)
Xero (ASX: XRO) remains one of the most trusted and widely followed technology companies among Australian investors. Known for its cloud-based accounting software, it supports millions of small and medium-sized businesses worldwide. The company’s ability to expand across geographies, particularly the UK and North America, has given it global scale, while its SaaS model ensures sticky, recurring revenues.
In June 2025, Xero announced the acquisition of US payments platform Melio for US$2.5 billion upfront, with up to US$500 million in contingent payments, valuing the deal at up to US$3 billion (around A$4 billion). This acquisition is transformative; it moves Xero from simply being an accounting solution into a fully integrated payments ecosystem. In our view, this dramatically increases its addressable market, while giving it a more compelling value proposition against global competitors like Intuit.
The company’s recent financials reinforce its strength. Xero reported double-digit revenue growth in FY2025, with operating margins expanding thanks to scale efficiencies. The fact that it continues to meet the “Rule of 40”, where revenue growth plus profit margin exceeds 40%, is evidence of both discipline and growth potential. For long-term investors, Xero looks like a resilient global SaaS winner.
NEXTDC (ASX: NXT)
As data becomes the foundation of the digital economy, NEXTDC (ASX: NXT) is positioned at the centre of this trend. The company currently operates 13 state-of-the-art data centres across Australia, with several more under development in Sydney, Melbourne, and Brisbane. Its facilities are NVIDIA DGX-Ready certified, enabling them to support advanced AI workloads, a critical growth driver as enterprises and governments accelerate AI adoption.
Over the past year, NEXTDC has enhanced its interconnection services to 100 Gbps capacity and deepened partnerships with global hyperscalers, positioning itself as more than just a landlord of data centres. It is now a connectivity hub for Australia’s digital economy.
From an investment angle, NEXTDC enjoys high barriers to entry. Building and running Tier IV data centres requires immense capital and expertise, which protects its market position. With long-term contracts and strong demand for AI-ready infrastructure, NEXTDC offers investors an infrastructure-backed way to participate in Australia’s digital growth story.
WiseTech Global (ASX: WTC)
How To Choose The Best-Performing Tech Stocks on the ASX?
Selecting the right ASX tech stock is not about chasing momentum; it’s about assessing quality. We suggest asking a few critical questions.
First, does the company have recurring revenue? Businesses like Xero and WiseTech thrive on subscription models that provide visibility and stability. Contrast this with companies reliant on one-off sales, which may struggle when demand softens.
Second, is the company exposed to structural megatrends? NEXTDC’s position in cloud and AI infrastructure is a perfect example. Even if short-term cycles fluctuate, long-term demand remains upward.
Third, does the company have global scale? The ASX market is relatively small, so companies with international exposure, like WiseTech and Xero, offer more diversified growth opportunities.
Fourth, what about valuation? The ASX 200 currently trades around 19× forward earnings, above its long-term average. Investors must be disciplined about entry points, ensuring the growth potential justifies the price. Overpaying for growth can be costly.
Finally, is management execution credible? Tech often relies on rapid innovation and acquisitions. The ability of a leadership team to integrate deals, sustain R&D, and manage growth responsibly is crucial.
Risks Of Investing In ASX Tech Stocks
As with any investment, risks are ever-present. In our view, there are several specific to tech investors should consider.
The first is seasonality. September has historically been the weakest month for global equities, with Wall Street showing average declines of 0.7–4% across decades. The ASX often follows global sentiment, meaning tech stocks could face short-term headwinds.
Are ASX Tech Stocks A Good Investment?
So, are ASX tech stocks worth your capital right now? We believe the answer is yes, if chosen wisely. The sector has demonstrated resilience in 2025, helping power the ASX 200’s double-digit return despite broader earnings challenges. Structural tailwinds, AI, cloud, software, and fintech, continue to drive demand. And companies like Xero, WiseTech, and NEXTDC are global leaders, not just local players. That said, investors must approach with discipline. Valuations are not cheap, and seasonality may add volatility in September. The key is to focus on companies with durable moats, strong earnings visibility, and exposure to megatrends. ASX tech stocks are not just a speculative play; they are a strategic allocation for growth-oriented portfolios.
