Founders, brothers John and William (Bill) Kinsella grew up in humble surroundings south of County Kilkenny, Ireland. While they no doubt had ambitions and adventures in mind, surely they wouldn’t have imagined they would one day head up a respected property development company like Billbergia, having enjoyed over 30 years of success.
John and Bill were born into a farming community in the picturesque village of ‘Móin Choinn’ (Mooncoin). Raised on a dairy farm with 1 other brother and 3 sisters, work on the farm started at an early age and John and Bill spent many cold dark mornings milking cows before a quick dash to make it in time for school.
John first came to Australia in the late 1970s after receiving a scholarship to visit and work on farms in Australia and New Zealand. It was from here that his love for Australia began. In 1981 he immigrated to Australia and worked on major infrastructure projects, where he got the opportunity to sub-contract one of the projects. John’s entrepreneurial vision took root and soon his brother Bill joined him.
John and Bill founded Billbergia in 1988 and grew the civil engineering business by sub-contracting civil construction projects around NSW. In 1991 the brothers joined forces with another growing civil engineering company, owned by another Irishman John Fitzgerald (now Operations Manager for Billbergia).
Through the 90’s they combined skill and knowledge to grow the business into a mid-tier construction company. As the decade progressed the business began to undertake larger and more technical complex projects such as The Coffs Harbour Major Water Upgrade, The Lismore Sewerage and Water Upgrade and The Perisher (Snowy Mountains) Treatment Plant and Pump Station Project to name but a few. These projects involved a lot of industrial building and John Kinsella enjoyed the challenges of the bricks and mortar part of the business.
In the late 90’s John saw an opportunity to branch into the residential housing market firstly developing in Annandale, followed by Marsfield, and Pymble.
After these initial successes, Billbergia began to focus more on the residential housing market and purchased a large site in Lane Cove, followed a couple of years later by their first waterfront site at Meadowbank.
The new millennium saw Billbergia grow into a large privately owned property developer with a strong and dedicated management team. Billbergia has built its business around a loyal group of long standing employees, consultants and contractors who have reciprocally contributed to the group’s success.
John and Bill are both married with grown families, John to Riezel (owner and founder of RK Realty Group) with sons John, Tom and Joseph and Bill to Iris (a Medical Doctor) with sons Killian and Leon.
