What DGH Engineering does

DGH Engineering Pty Ltd is a privately held Australian metal engineering and fabrication services company founded in 2005 and headquartered in Mackay, Queensland, with 250+ employees operating across five regional Queensland locations (Mackay, Townsville, Emerald, Gladstone, Proserpine). The company delivers an integrated 'one-stop shop' portfolio spanning custom metal fabrication (structural steel, stainless steel, aluminium), pressure vessel and boilermaker fabrication compliant with AS 1210:2010 and ASME BPVC, mining equipment engineering, on-site SMP/EPC services, CNC and manual fitting and machining using Doosan equipment, design and drafting in AutoCAD/Inventor/SolidWorks, blast/paint/industrial tiling/poly spraying in an 800m² undercover facility, and specialised shutdown planning and delivery. It also offers EZ-AS, a proprietary preventative maintenance software for asset tracking, work orders, compliance, and inspections.

The business serves enterprise clients primarily in mining (BHP, BMA, Pembroke Resources/Olive Downs), ports, water infrastructure (Sunwater), defense (Crowley for US Defense fuel storage), sugar (Wilmar), refineries (Sun Metals), agriculture, and local government/councils, with revenue generated via project-based professional services contracts and managed shutdown/maintenance services. Pricing is custom-quoted per project with no public pricing tiers, and all services are delivered directly through DGH's workshops and embedded on-site teams rather than via channel partners.

The company is founder/management-owned, led by Managing Director Trevor Wellby since 2005, and differentiated by quadruple certification (ISO 9001, ISO 14001, ISO 45001, AS/NZS ISO 3834.2 — the latter held for 9 consecutive years, making DGH Queensland's longest consecutively qualified welding business), a 3,000 injury-free days safety milestone at BHP's Hay Point Coal Terminal, and the EZ-AS software product. No external investors, funding rounds, M&A activity, or AI/ML capabilities are disclosed.

Direct peers

• Macmahon Holdings: ASX-listed mining contractor providing surface mining, underground mining, and civil infrastructure services across Australia. Comparable in targeting the same Tier-1 mining customers and operating in similar regional Queensland geographies, with overlapping maintenance and shutdown service lines.
• Bis Industries: Australian mining and industrial services contractor providing maintenance, shutdown, and fabrication to resource customers. Comparable customer segments and regional presence, particularly across Queensland coal and metalliferous mining.
• Monadelphous Group: ASX-listed engineering contractor providing fabrication, structural mechanical piping, and maintenance services to mining, energy, and infrastructure clients across Australia. Closest publicly traded peer — similar service mix, customer base, and project delivery model to DGH, but at significantly larger scale.
• NRW Holdings: ASX-listed diversified mining services contractor offering civil construction, equipment hire, and maintenance to Australian resource clients. Comparable regional operating model and mining-customer overlap with DGH, particularly across the Bowen Basin and broader Queensland.
• Mader Group: ASX-listed mining maintenance and shutdown specialist providing electrical, mechanical, and fabrication services to Australian resource customers. Highly comparable in business model, customer base, and regional operating footprint, though larger and more diversified across multiple commodities.

Broad incumbents

• Sedgman (CIMIC Group): Australian mineral processing and engineering specialist within the CIMIC group, delivering coal handling and preparation plant (CHPP) design, construction, and maintenance. Directly comparable on CHPP-related fabrication work that DGH performs for customers such as Pembroke and BMA.
• Clough Limited: Australian engineering and EPC contractor delivering projects across mining, oil and gas, and infrastructure. Overlaps with DGH on process plant fabrication and on-site construction but is substantially larger and focused on major capital projects.
• Downer EDI: ASX-listed infrastructure and mining services conglomerate with extensive fabrication, maintenance, and shutdown capability. Competes with DGH on large mining and infrastructure contracts but operates at a national scale with a much broader service portfolio.

Emerging players

• Action Drill & Blast: Australian mining services contractor specialising in drill and blast, with adjacent maintenance offerings. Smaller and more focused than DGH, but competes for similar Tier-1 mining contracts and shares a Queensland operating footprint.

Others

• GHD Group: Global engineering, architecture, and project management consultancy headquartered in Australia. Comparable in design and drafting capability and in serving water, mining, and infrastructure clients, though operates as a professional services firm rather than a fabrication contractor.
