Crosstalk Technical Services has supplied Katoomba Christian Convention with AV services for three decades. Whether the event has been for 10,000 people or 100, whether complex or straightforward, Crosstalk has consistently delivered what we have needed, on time and on budget. You can rely on Crosstalk, and we highly recommend them.

Crosstalk’s founder, Steve Williams, began technical ministry whilst still in High School. This ad-hoc ministry grew until the late 1980’s when Crosstalk Technical Services was set up to offer specialist production, technical advice and training services to churches, schools and Christian organisations predominantly in Sydney and the surrounding suburbs.
Whilst working as a teacher, Steve spent many holidays and weekends doing tech related ministry as well as undertaking a number of school-based productions. It was during the late 1990’s that it became obvious there was a clear need for a ministry-based approach to the provision of technical services in a way where training, skill-sharing and partnership underpinned the ministry.
Identifying a significant need for production and event services offered specifically within a ministry framework, Steve left his school teaching career to focus entirely on Crosstalk Technical Services from 2004. Since then, Steve and a more than 20-strong team of like-minded “techies” have built Crosstalk into a reputable provider, trusted by high profile schools, churches and conference organisers to deliver professional events, training and technical support with honesty and integrity.

Client Testimonials
We absolutely love working with Crosstalk! Steve and his team have shared their wealth of knowledge and experience with us for over 10 years on our large-scale showcase events and musicals, as well as training in audio and lighting and many other events. In each instance, Crosstalk has effortlessly and professionally handled with excellence anything that we have thrown at them.
In my experience, it is very rare to have technical teams that are so dedicated to caring for and supporting students involved in the production.
We look forward to many more years of working alongside Crosstalk!
What an amazing evening our Speech Night was, thanks in large part to the magnificent contribution of you and your crew.
I truly appreciated your help and friendliness right from the start (during our first meeting as you explained what was required and how things panned out on the night), when we met the Town Hall people and finally your quiet confidence and professionalism on the night.
A sincere thank you to you and your team for your friendliness and professionalism.
Crosstalk Technical Services have been a significant contributor to the success of Christian Venues Association’s conference events for over eight years. In my time as CEO of the Association, I appreciated the professionalism, advice, commitment, timeliness, support and overall excellent work by Steve and his team. Not only had they covered the technical aspects of the audio-visual needs completely but did so as a partner in ministry.
