About BIGA+ Buyers Independent Group Australia


Buyers Independent Group Australia ...
...for the Member, run by our Members


The Buyers Independent Group of Australia (BIGA) was formed in 1994 by a small number of independent Members. These founding Members were represented by BIGA, as a group of Independent Plumbing, Bathroom and Building Supply Company's to streamline their purchases collectively, whilst maintaining separate trading identities within their marketplace.

The Group's Board is selected and directed by the Group Members and consists of prosperous and competent business men/women who all have extensive business and industry experience. Their aim is to regulate our members and form a strategic alliance with a select number of suppliers who are willing to work closely with the Group to achieve our combined goals.

The Group's Suppliers enjoy preferential purchasing status, while our Members enjoy competitive purchasing, allowing both to gain market share in an extremely competitive industry.

The Group Membership has National representation, rapidly growing enabling us to reinforce and consolidate our Group's position within the marketplace. This continuing expansion resulting in recognition in the Industry as one of the most Professional Consolidated Buying Groups.

Our Vision Statement

"...To be the most professional National Distribution Coordinated Group based upon Independent Membership. This individual Membership supplying a vast range of quality Plumbing Bathroom and Building Products."




Jamiesons Joinery & Building Centre


We pride ourselves on specialising in the best brands and the latest trends.


"...Jamiesons Joinery & Building Centre has been a Member of the Buyers Independent Group Australia (B.I.G.A) since its formation in 1994.

With the expansion of our original Joinery Business, we soon found it necessary to become a Member of a Plumbing and Building buying group that would enable us to compete in a highly competitive market.

The B.I.G.A Group structure suited our Business model and allowed us to retain our local store identity and retain full control of our Business. The networking and financial benefits associated with being a member has seen our Business grow and flourish.

We would highly recommend the B.I.G.A group as an option in helping your Business move forward. ..."
