Direct peers

• Downer EDI: ASX-listed infrastructure group with a dedicated Utilities division delivering design, construction, operations and maintenance for electricity, gas and water networks across Australia and NZ. One of Zinfra's most direct and well-capitalized competitors in tenders for major network owners.
• Ventia: Leading Australian and New Zealand infrastructure services provider with a sizeable Utilities sector covering electricity and gas network operations and maintenance, as well as transport and water. A direct peer on long-term O&M frameworks and a frequent bidder against Zinfra for utility clients.
• Service Stream: ASX-listed Australian infrastructure services company delivering design, construction, operations and maintenance across electricity, gas, water and telecommunications networks. Directly comparable to Zinfra across the core utility-services stack and competing head-to-head in Australian O&M tenders.
• Monadelphous: ASX-listed engineering and infrastructure services firm delivering maintenance, construction and engineering support to the energy, resources and infrastructure sectors in Australia. Comparable to Zinfra in field-workforce-led utility execution and multi-disciplinary engineering delivery.
• Genus Plus Group: Australian infrastructure services company focused on power transmission, distribution and substations, supplying design, construction and maintenance to major utility clients. Highly comparable in service scope and customer base (including AusNet and Western Power), making it a near-direct peer.

Broad incumbents

• Worley: Global engineering and project delivery firm headquartered in Australia with a sizeable Energy and Industrial infrastructure business. Comparable to Zinfra in delivering engineering, project management and asset services for energy clients, but at materially larger scale and global reach.
• CPB Contractors: Tier-1 Australian EPC contractor (CIMIC-owned) delivering major transport, utilities and energy infrastructure. Has partnered with Zinfra on the West Gate Tunnel Project and represents a broader incumbent whose scale outstrips Zinfra's on very-large-scale bids.
• John Holland: Major Australian construction contractor (CIMIC-owned) with capabilities spanning rail, utilities, civil and tunnelling. A counterparty to Zinfra (e.g., CPB/JH JV on West Gate Tunnel utility relocation) and a broader incumbent competing for large-scale transport and energy infrastructure work.

Others

• Acciona Energy: Global renewable energy infrastructure developer and constructor; Zinfra has delivered utility-power works on Acciona's CBD and South East Light Rail project. Adjacent infrastructure participant that represents the renewable/transport developer client base Zinfra services.
• APA Group: Australia's largest natural gas infrastructure business and a Zinfra customer for gas transmission projects. Comparable as an adjacent infrastructure participant in the Australian gas value chain rather than a direct services competitor.
