What Mainbrace Constructions does

Mainbrace Constructions is an Australian commercial construction company founded in 1989 by Greg Millson and Peter McKinnon, headquartered in Sydney with regional offices in Brisbane (opened 2010) and Melbourne (opened 2015). It specialises in retail construction — supermarkets, shopping centres, department stores and specialty retail — which represents approximately 80% of its portfolio, supplemented by a logistics and industrial construction line (~20% of revenue) and selective non-retail work spanning education, commercial and lifestyle sectors. The company delivers projects ranging from under $100K to over $200M for an enterprise client base that includes Woolworths (550+ projects), Coles, ALDI, Costco, Amazon, David Jones, Bunnings, Ampol, Vicinity Centres and Stockland, supported by a dedicated Small Works division and an Early Contractor Involvement (ECI) pre-construction service that accounts for around 20% of projects.

The business operates on a project-based construction revenue model — fixed-price and cost-plus contracts for one-off delivery — with revenue recognised over the construction period. Go-to-market is direct enterprise sales through state managers in NSW, QLD and VIC, underpinned by an 85% repeat-client rate, 94% on-time delivery and a portfolio of 1,800+ projects totalling $6.7B+ in cumulative value. Mainbrace uses cloud-based project management and Business Intelligence software to analyse project data, maintains ISO 9001:2015 and ISO 45001:2018 certifications, and has built sustainability capability including Green Star and NABERS delivery. The company is privately held under a Pty Ltd structure, has never relied on debt or overdraft facilities, and is led by Managing Director Rob Doust (with the company since 1993) following the 2024 retirement of long-serving Director Greg Scott and 2025 appointments of Daniel Morelli and Angus Greenwood as Directors.
