This review provides a comprehensive analysis of the suitability of steel helical pile groups as a foundational solution for expanding energy transmission networks with specific focus on Australia. It synthesizes a wide array of research, from government policy and industry plans to geotechnical studies and engineering case histories, to evaluate the technology's performance against critical technical, logistical, and economic criteria. The analysis confirms that Australia is on the cusp of an unprecedented energy transi-tion, necessitating the rapid and efficient deployment of thousands of kilometres of new transmission infrastructure. Traditional foundation methods, such as bored Piles, are proving to be a bottleneck due to their reliance on complex logistics, extensive site work, and high material and labor costs. The findings of this review conclude that steel helical pile groups represent a superior, more resilient alternative. Their inherent advantages—including a design that funda-mentally mitigates the risks of Australia's expansive clay soils, a lower-impact installa-tion process, immediate load-bearing capacity, and a verifiable quality control method-ology—directly address the core challenges facing major projects. The use of prefabri-cated steel piles, which are manufactured in-house and can be deployed with smaller crews and equipment, dramatically reduces on-site labor hours and eliminates the need for concrete curing. Furthermore, the minimal environmental footprint, including a significantly lower embodied carbon profile, aligns with modern sustainability goals and helps secure the social license to operate for large-scale infrastructure projects. This review recommends that helical pile technology be considered a primary solution in the early stages of design for future transmission and renewable energy projects. To accelerate its adoption, there is a clear need for formalized, Australian-specific engi-neering guidelines and the establishment of local pilot projects to provide a definitive public demonstration of their performance, productivity, and cost-effectiveness. The strategic adoption of helical piles is not merely a matter of technical preference but a critical component of a robust, cost-effective, and sustainable approach to modernizing Australia's energy grid.
