Graciete Ferreira

Ms Ferreira formerly chaired the MBA’s subcontractor and supplier sector council. She has served on the board for the past decade. The appointment reflects the growing importance of subcontractors in the MBA ACT and in our industry. This is the first time a subcontractor has become president of the MBA ACT, or any other MBA nationally. It is also the first time in our 125 year national history that a woman has been appointed President.


Frank Porreca

During Mr Porreca's eight year commitment on the MBA board, the Association has raised more than $3 million for the local community.

To Mr. Porreca, "Being a Master Builder means more than just building good quality homes and having good customer service, but it also means giving back to the community that supports our industry. Master Builders supports the ACT community through MBA Charity Houses, and raising funds through various MBA events."

Frank Porreca also continues to work closely with the ACT Government on a range of policy and advocacy priorities for the local construction industry.
