How We Do It


Our mission is to collaborate creatively with our clients from initial project conception.  By listening carefully to our clients’ briefs and creative direction, we plan, prove, and perfect fabrications.   We assert our passion for applied industrial imagination.  As we conceive design and engineer our clients’ work in-house, there is better communication that delivers better products and eliminates further mark-ups from outsourcing.
We are a “turn-key” solution provider.  We are not being afraid to take on never-been-done-before projects and we won’t compromise on quality to stay in our comfort zone.

What sets Big Kahuna apart is our extra-ordinary attention to detail, our ability to find unique solutions and inject true invention as required.

We are original. We invent. We test. We deliver.

Big Kahuna’s extensive ‘in-house’ production facilities can accommodate the fabrication of a range of projects.
We work with an extremely broad range of materials and production methods utilising modern and classical technical effects solutions.

The range of creative techniques we use is in-line with the diverse requirements of our clients.

  • Play Communication has built an excellent relationship with Big Kahuna Imagineering over the last few years.  The highly skilled and imaginative team at Big Kahuna has proven to be an asset in the creative realisation of numerous devices and sets for our experiential marketing campaigns.

    A demonstrated ability of BKI to fulfill project deliverables from the initial concept stage through to installation and service is impressive both from the creative as well as the commercial perspective.  Their collective wealth of knowledge, artistic integrity and no-fear attitude when it comes to fast turn-around, innovative and never-been-done before briefs is refreshing.

  • oOh!media have worked together with Big Kahuna to develop and produce creative solutions for major experiential campaigns.

    Their professional and detailed approach to client service, creative development and production is evident in the final execution.  They are one of the rare suppliers whose end result is as good, if not better than the concept.

    We continue to engage them for future campaigns as we know we can rely on them for timely delivery, excellent service, creative solutions and quality production.

  • When big thinking meets passion, dedication and expertise you get a project like the Hondatrope. A well engineered, ergonomically optimal interactive spinning cup device.

    From design through to execution, BKI developed a highly engaging device that exceeded our expectations from the tight schedule through to the very stringent safety provisos. BKI delivered on the brief in bringing Honda’s brand to life with “The Power of Clever Thinking”.

    Will and the team at BKI have again proven to be a reliable turnkey provider, capable or taking the largest and loosest of ideas, adding their respected and valuable input, informed design decisions and the many well considered ergonomic considerations, to successfully engineer a project that comes to life flawlessly in the real world environment. Delivering joy to our audience through an authentic brand activation.

  • Will and his team were contracted to fabricate two spectacular and complicated pieces for the Asian Games held in Doha in 2006.
    I would like to emphasise the balance for between our high end computer graphic conceptual and the finished product which at times can be a let down.  This was the greatest achievement in our project highlighted by the Big Kahuna team’s ability and in the Emir of Qatar’s words “Exceed his most sanguine expectations”

    I do not provide my endorsement lightly or without on road and contemporary experience.  The depth of experience in custom fabricating  and technical breadth of BKI was evident whilst maintaining a financial boundary that made the result possible.

    I have no hesitation recommending him.  Our production is very pleased with the spectacular effort and finish that has gone into our project.

    We have worked closely with their team on many projects and campaigns over the years and have found them a very easy and professional company to work with.  I would not hesitate in recommending them and one of the BEST in the field.

  • Right from the initial development of the concept of our insurance happiness character (Doris the Duck and her ducklings)…to her successfully landing on our doorstep, I have been delighted  with the high standard of excellent work of Will and the team at Big Kahuna.  They professionally managed our expectations during the total process and were very flexible in providing solutions to any of our requests that arose along the way.  Their proactive commitment to our business ensured that Doris had a very smooth entry into our world.  Since her introduction, Doris has been overwhelmingly embraced by our colleagues and our customers.

    Many thanks to all of the team at Big Kahuna for the outstanding service you have provided to us.
