If you're lucky enough to have $5,000 ready to put into the share market this month, exchange-traded funds (ETFs) could be one way to do it.
They can be a simple way to spread your risk and tap into powerful long-term themes. Rather than betting on a single stock, these funds offer diversified exposure to dozens — or even hundreds — of shares at once.
Here are four ASX ETFs worth considering in September.

Betashares Global Robotics and Artificial Intelligence ETF (ASX: RBTZ)
The first ASX ETF to consider for a $5,000 investment is the Betashares Global Robotics and Artificial Intelligence ETF. It gives investors access to companies shaping the next wave of industrial and digital innovation. From surgical robots to factory automation and advanced AI software, the fund's holdings are involved in technologies that are steadily moving from experimental to mainstream use.
The common thread is efficiency: businesses and governments alike are adopting robotics and AI to cut costs, improve accuracy, and solve labour shortages. That structural demand could underpin years of growth for the companies inside the Betashares Global Robotics and Artificial Intelligence ETF. It was recently named as one to consider by the team at Betashares.
Betashares Asia Technology Tigers ETF (ASX: ASIA)
Tech leadership isn't confined to Silicon Valley. Asia is home to some of the world's fastest-growing and most innovative companies. The Betashares Asia Technology Tigers ETF offers exposure to giants like Alibaba, Tencent, and TSMC, which dominate e-commerce, gaming, and semiconductor manufacturing.
The rise of Asia's middle class and rapid adoption of digital technologies make this region a long-term growth hotspot. For investors looking to balance their global tech exposure, the Betashares Asia Technology Tigers ETF provides a powerful way to diversify beyond the U.S.
Betashares Australian Quality ETF (ASX: AQLT)
Chasing high growth is exciting, but owning quality shares is what helps portfolios compound safely over decades. The Betashares Australian Quality ETF focuses on Australian shares with strong balance sheets, consistent profitability, and low levels of debt. These are the kinds of companies that can weather downturns and still deliver for shareholders.
Including the Betashares Australian Quality ETF in your portfolio helps ensure you're not just riding short-term fads but anchored in durable businesses that represent the backbone of the ASX. It is another ASX ETF that Betashares thinks investors should consider buying.
Betashares Australian Momentum ETF (ASX: MTUM)
Sometimes the best indicator of future performance is current performance. The Betashares Australian Momentum ETF tracks Australian shares that are showing strong share price momentum, aiming to capture trends early and ride them higher.
Momentum strategies can be volatile, but they often shine when markets are climbing — as we've seen with the ASX 200, which has gained more than 10% over the past year despite global uncertainty. The Betashares Australian Momentum ETF lets you systemise this approach without having to pick and trade the individual winners yourself. It was also tipped as one to consider buying by the fund manager.
