As the Australian Securities Exchange (ASX) nears record highs and investor sentiment improves, many Australians are seeking investment opportunities for their $10,000. Exchange-traded funds (ETFs) offer instant diversification, access to entire sectors or themes, and the ability to compound returns over time without the stress of stock-picking. Here are three ASX ETFs that could be worth considering in October.

Betashares Global Defence ETF (ASX: ARMR)

The Betashares Global Defence ETF provides exposure to leading defence, aerospace, and cybersecurity stocks benefiting from increased global defence spending and geopolitical tensions. This fund includes global defence giants such as Lockheed Martin (NYSE: LMT), Northrop Grumman (NYSE: NOC), and Raytheon Technologies (NYSE: RTX). These companies supply advanced defence systems and technology to the United States and allied nations. Defence has historically been a resilient sector, performing well even during periods of market volatility. With governments prioritising security and military modernisation, demand for high-end defence solutions is expected to keep growing, according to a Fool Australia article.

Betashares S&P/ASX Australian Technology ETF (ASX: ATEC)

The Betashares S&P/ASX Australian Technology ETF offers access to Australia's most innovative tech stocks, poised for growth with increasing digitalisation. This fund includes companies like WiseTech Global (ASX: WTC), Xero (ASX: XRO), and NextDC (ASX: NXT). WiseTech continues to dominate global logistics software, Xero remains a leader in cloud-based accounting, and NextDC is capitalising on the surging demand for data storage and artificial intelligence. By investing in this ETF, you gain exposure to Australian innovators that could deliver outsized returns as digitalisation and automation reshape the economy over the next decade, as noted in the same Fool Australia article.

Betashares Australian Small Companies Select ETF (ASX: SMLL)

The Betashares Australian Small Companies Select ETF focuses on small-cap stocks with positive earnings and strong valuations, providing growth potential without exposure to riskier speculative shares. This fund tracks the Nasdaq Australia Small Cap Select Index, which screens for small-cap shares with positive earnings, strong debt servicing ability, and solid valuations. By investing in this ETF, you benefit from the growth potential of Australia's next generation of corporate leaders. The fund generally holds between 60 and 90 stocks, offering instant diversification, as highlighted by the same Fool Australia article.

These three ETFs offer instant diversification, exposure to resilient sectors, and the potential for outsized returns over time. Defence, tech, and small-cap companies are expected to perform well amid ongoing geopolitical tensions and digital transformation.
