Australian Growth Stocks To Own In October 2026

Global trade is being rewired as companies rethink how they source and ship goods, with supply chain flexibility now a genuine competitive edge rather than a buzzword. Australian growth stocks where founders and executives still own meaningful stakes can be well placed to react quickly, because decision makers feel the impact in their own wealth. This article walks through three such insider backed growth stories from the local market.

The three stocks highlighted here offer a compelling starting point if you want exposure to fast growing businesses where insiders and analysts are aligned on the outlook. However, if you want the pick of this theme, these 27 high growth high conviction stocks are the best of the best.

Telix Pharmaceuticals (ASX:TLX)

Telix Pharmaceuticals fits this fast growing, insider aligned theme through its late stage radiopharmaceutical pipeline, where Phase 3 cancer therapies and diagnostics sit alongside an already commercial business that gives real world proof of demand for its precision imaging approach.

Telix Pharmaceuticals develops radiopharmaceutical diagnostics and therapies across prostate, kidney, brain and other solid tumours, with most of its roughly $704.7 million in revenue coming from Precision Medicine and a further $277.1 million from Manufacturing Solutions. The business is sizeable already, with a market value near A$5.1 billion.

"Their primary revenue generating imaging agents, 'Illuccix' and 'Gozellix', are utilised in 23+ countries worldwide, including key markets such as the U.S, Europe, China and Japan, with revenue figures of $803.8m (USD) in the 2025 Financial Year (within their already upgraded guidance range) provided for FY25, a cash balance of $141.9m (USD), and the potential growth of Gozellix as its launch into the U.S expands."

What really matters now is how one unresolved pressure around funding and capital intensity shapes the payoff from that expanding product footprint.

That funding question is exactly what the full narrative for Telix Pharmaceuticals unpacks, tracing how Telix Pharmaceuticals could balance capital demands with an accelerating product rollout inflection.

Codan (ASX:CDA)

Codan plugs directly into the Fast Growing Stocks With High Insider Ownership theme through its Communications arm, which sells high margin tactical radios and public safety systems into defence and emergency markets that many investors see as long term growth arenas.

Codan designs and sells communications gear and metal detectors, generating about A$506 million from Communications and A$362 million from Metal Detection, with a market value near A$11.0b.

"Heightened geopolitical tensions, increased defense spending, and the need for resilient communications infrastructure, especially in light of remilitarization and growing demand for unmanned systems, are expanding Codan's customer base and forward order book in defense and public safety, contributing to both near-term and long-term revenue."

The real swing factor is how one pressure on future contract quality and mix shapes the durability of those healthy margins.

That contract mix risk is exactly what the full narrative for Codan unpacks, showing how Codan's defense communications engine could continue to accelerate even if order quality and timing shift.

Southern Cross Electrical Engineering (ASX:SXE)

Southern Cross Electrical Engineering brings that fast growing, insider aligned theme into the real world through large scale electrical and maintenance work, where decarbonization projects in renewables and electrified mining sit alongside more traditional commercial and infrastructure contracts.

Southern Cross Electrical Engineering generates A$718.7 million from electrical, security and communication services in Australia, with a market value near A$1.3 billion.

"The company sits downstream of powerful structural drivers, AI workloads, cloud migration, enterprise digitalisation, and data sovereignty requirements, all of which are driving sustained demand for data centre capacity."

What really moves the needle now is how one unresolved pressure on converting that project pipeline into higher, more stable margins ultimately plays out.

To see how that margin story could accelerate or stall from here, read the full narrative for Southern Cross Electrical Engineering for what the full project pipeline is really signalling.
