Overview
Insurance Australia Group (IAG) is Australia’s largest general insurance group — an umbrella organisation, listed on the ASX, that owns well-known customer brands including NRMA Insurance, CGU, SGIO, SGIC, and WFI rather than selling under its own name (Insurance Business). Its origins lie with the National Roads and Motorists’ Association, which began offering motor insurance in New South Wales and the ACT in 1920 (Insurance Business). After a nationwide expansion in the 1990s — including the 1998 purchases of state-owned insurers SGIO (WA) and SGIC (SA) and a 1999 joint venture with Victoria’s RACV — NRMA demutualised in 2000, separating road services from insurance and issuing shares to members (Insurance News). The listed entity was renamed Insurance Australia Group in 2002 (Insurance Business).
Built by acquisition
IAG’s defining deal came in January 2003, when it completed the acquisition of CGU and NZI — described at the time as a coup, capturing one of Australia’s largest commercial insurers (Insurance News). The four-year transformation took the group from a NSW-based business of a couple of thousand employees to a listed company of around 11,500 staff, half outside NSW (HR Director). Through CGU, IAG inherited an insurance lineage stretching back to the Great Fire of London in the 1660s — a heritage its integration team deliberately made the cultural anchor of the merged business (HR Director). Later deals added AMI (2012) and Wesfarmers’ insurance underwriting businesses (2014), and in 2015 Berkshire Hathaway took a 3.7% stake — the same era in which IAG launched its $75 million start-up fund, Firemark Ventures (Insurance Business).
Unifying the empire
A group assembled by acquisition was, by 2015, “a series of independent silos, each of which carried its own systems and cultures” (Insurance News). CEO Peter Harmer’s answer was the Australia Division — a single unit centralising accountability for customer, product, distribution, and operations — and Federal Court approval to consolidate nine insurance licences into two: Insurance Australia Limited and the RACV-part-owned Insurance Manufacturers of Australia (Insurance News). Nick Hawkins, a 12-year CFO of the group, became managing director and CEO in November 2020 (Insurance Business). Today the group counts more than 8.5 million customers and underwrites around $12.6 billion in premiums a year (Insurance Business).
