About Us

Billbergia is a private, integrated Australian property group and one of the largest developers of waterfront apartments in Sydney. Having over 25 years of experience the group has a proven track record in delivering on their motto “Creating Communities”.

Founded by brothers John and Bill Kinsella in 1988, the group has remained privately owned with a strong and dedicated management team. Over this time, 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. Billbergia’s in-house professional skills include development management, construction management, design, project management, civil engineering, structural engineering, plant hire, quality assurance, project marketing and sales, finance and legal work.

In addition to their own projects, Billbergia provides professional engineering and project management services to the residential, local government and commercial sectors of the construction industry.

The group has an enviable history of working cooperatively with corporate and commercial partners (including joint venture structures), loyal consultants and subcontractors as well as supporting underprivileged communities. Billbergia values taking an ethical position on all matters and being transparent throughout its business process is a priority.
