Top 3 Australian Growth Stocks To Watch In October 2026

Asian tech stocks recently surged after SK hynix reported record earnings tied to strong semiconductor demand for AI, reminding investors how quickly sentiment can swing toward growth. Australian high growth potential stocks that combine solid balance sheets with strong earnings expectations tap into that same appetite for future upside. This article highlights three such companies from our screener for investors who want clear growth stories and healthier finances.

The three stocks highlighted here offer a compelling starting point if you want exposure to financially healthier, high growth potential businesses where analysts see strong earnings expectations. However, if you want the names that matter most, these 33 best high growth potential stocks are the strongest companies we've found.

Electro Optic Systems Holdings (ASX:EOS)

Overview: Electro Optic Systems Holdings develops space sensing and laser tracking systems alongside advanced defence weapon platforms serving global government customers.

Operations: Electro Optic Systems Holdings currently generates about A$241 million from Defence and around A$12 million from its Space segment.

Market Cap: A$2.0 billion

Electro Optic Systems Holdings fits the Healthy high growth potential theme because its space sensing and laser tracking technologies sit directly in fast-expanding defence and commercial space markets, giving analysts a clear earnings improvement story to model.

"Market optimism may be pricing in a prolonged period of elevated defense spending and geopolitical tensions, anticipating sustained contract wins and revenue growth for EOS; if these trends reverse due to arms control or shifting government priorities, revenue expectations could be at risk."

The real swing factor for Electro Optic Systems Holdings is how one future funding and demand pattern shapes the path of margins and growth.

That funding path is exactly what defines the risk or reward profile investors care about, which is why reading the full narrative for Electro Optic Systems Holdings helps you see how the thesis could accelerate.

4DMedical (ASX:4DX)

Overview: 4DMedical develops non invasive lung imaging hardware and software that help hospitals and drug companies measure and track respiratory function in detail.

Operations: 4DMedical generates about A$7.1 million from lung function analysis technology, with around A$6.9 million earned in the United States and A$0.2 million in Australia.

Market Cap: A$2.2 billion

4DMedical fits the Healthy high growth potential theme because its respiratory imaging platform turns complex lung function data into billable clinical scans and analytics services that can scale across hospitals and pharma programs.

"Partnership with Philips promised a $10Million USD minimum order commitment contract over the next 2 years starting December 2025 (over 2026 and 2027). Philips has added 4DMedicals CT:VQ technology as an official product on their catalog in North America."

What happens to earnings power if that new installed base translates into steady scan volumes on high margin software over the next few years.

If that earnings power is what you care about, read the full narrative for 4DMedical to see how 4DMedical’s contract pipeline, pricing and risks could evolve next.

Netwealth Group (ASX:NWL)

Overview: Netwealth Group runs an Australian wealth platform that hosts superannuation, investment and managed account products for advisers and retail clients.

Operations: Netwealth Group generates about A$389.7 million from platform operations in Australia, reflecting a single-country, single-engine revenue model.

Market Cap: A$4.2 billion

Netwealth Group matters for the Healthy high growth potential screener because its fee based wealth platform turns rising adviser inflows into recurring earnings that can scale efficiently if client assets keep building.

"Netwealth's continued investment in best-in-class digital experience, platform functionality, and data analytics aligns with the ongoing digitisation of financial services and increasing regulatory focus on transparency, positioning the company to capture greater adviser and client net inflows, bolster revenue growth, and strengthen platform stickiness."

What really decides how powerful that growth story becomes is whether one quiet pressure on profitability breaks in Netwealth Group’s favour.

If that pressure breaks the right way, the full narrative for Netwealth Group shows how Netwealth Group’s earnings engine could accelerate while key risks remain tightly contained.
