Supporting a Major International Congress on the Future of Work
IndustriALL Global Union hosted its 4th Global Congress at the International Convention Centre (ICC), Sydney, from the 1st to the 8th of November 2025. Under the slogan “Organising for a just future,” the congress brought together around 1,000 international union leaders and delegates to assess priorities, pass resolutions, and progress regional and thematic agendas, with Prime Minister Anthony Albanese and other high-profile guests attending key plenary sessions.

Congress Australia was entrusted with delivering a stable, high-performance simultaneous interpretation solution that seamlessly connected on-site and remote interpreters with on-site delegates. Delegates could follow proceedings in up to 12 languages without interruption.
Integrated Interpretation, AV, and Production Across Multiple Rooms
To support an assembly of this scale and complexity, Congress Australia delivered a complete hybrid multilingual solution across three meeting rooms and the Grand Ballroom, ensuring stable distribution and consistent operation throughout a dense, fast-moving program. The solution focused on two core elements: a reliable multilingual language distribution system and an integrated AV system platform that centralised conferencing, automatic camera control, streaming, and recording.
Reliable Multilingual Delivery for Every Delegate
The interpretation solution was designed to maximise flexibility, scalability, and reliability across the entire program. Most interpreters worked remotely via Zoom, supported by four ISO-compliant interpreter booths onsite for a select group of local interpreters.
This hybrid model enabled over 20 remote and onsite interpreters to seamlessly service every meeting room, delivering up to 12 languages simultaneously. Through tight integration between Zoom language channels, the Bosch Dicentis conference system, and infrared language distribution, delegates received uninterrupted, high-quality interpretation through wireless infrared headsets.
Congress Australia technicians provided dedicated technical support throughout the event, assisting both remote and onsite interpreters to maintain stable connections, resolve issues quickly, and ensure interpreters could focus fully on delivering accurate and professional interpretation. The result was a fully unified multilingual environment that adapted smoothly to changing schedules and language requirements, while consistently maintaining a premium delegate experience.

Integrated Conferencing, Camera Control & Production
Avonic 4K PTZ cameras were tightly integrated with the Bosch Dicentis and Bosch CCS1000 conference microphone platforms, enabling fully automated, speaker-driven camera tracking in every meeting room. As delegates activated their microphones, cameras responded instantly and consistently, delivering polished, professional coverage without the need for manual operation.
In each room, MVI software was deployed as the central operational hub, bringing conferencing audio, PTZ camera control, graphics, AV routing, streaming, and recording into a single, unified interface. Running on a dedicated high-specification PC, MVI enabled one technician per room to manage what would traditionally require multiple systems and control points, streamlining workflows while reducing complexity and operational risk. This consolidated control environment ensured consistent setup, faster changeovers, and confident delivery across all sessions, even with parallel rooms and evolving requirements.
This integrated approach improved reliability and consistency across the conference. With multiple sessions running simultaneously and minimal reset time between rooms, the MVI workflow supported clean transitions, synchronised outputs, and accurate recordings of proceedings for post-event access and reporting, regardless of language or room.
For a high-profile global congress with evolving requirements, the team’s responsiveness and technical expertise were exceptional

Managing Complexity Across Hybrid and Multi-Room Environments
Synchronised Activation Across Multiple Rooms
With the event spanning multiple rooms, the setup was strategically planned and crewed. On-site installation commenced on 1 November, ahead of the official congress start on 4 November. The initial setup took place on Level 4 of the ICC, where all three meeting rooms were installed concurrently and completed within a single day. Each room was equipped with full audio, vision, and interpretation systems, followed by a comprehensive run-through with the venue AV team to enable testing before day one. While Level 4 was installed and operating, a second team began the Grand Ballroom installation in parallel. As Australia’s largest ballroom, it had significantly more complex technical requirements. This scope included truss-mounting 20 infrared radiators, installing interpreter booths, configuring 40 microphones, deploying 1,000 infrared receivers and headsets, and establishing streaming pathways and network connectivity.
Given the overlapping schedules and compressed turnarounds between spaces, we increased staffing levels and assigned dedicated technical teams to each room. This ensured continuity, accountability, and consistent system standards across all venues, while maintaining momentum under tight timelines. Through structured workflows, parallel installation, and proficient crew allocation, we successfully navigated the complexity of synchronised activation across multiple rooms, delivering a stable, fully tested environment ready for delegates from day one.
Limited Testing Windows
With multiple session formats running simultaneously across several rooms, turnarounds between meetings were extremely tight, leaving little time for testing or resets. Nevertheless, the team kept the system stable by continuously monitoring performance, conducting daily interpreter checks, and making efficient configuration changes between sessions, so every room started on time and ran smoothly.
Evolving Requirements
To manage evolving technical requirements without impacting live operations, we built flexibility into the delivery from the outset, both in planning and system design. Ahead of the event, Congress Australia completed two site visits to validate room layouts, confirm venue integration points, and align operational workflows with the venue's AV requirements, with local union representatives coordinating on-site activities. As the event progressed, additional requests were introduced, most notably expanded streaming requirements and additional display outputs. Rather than treating these as disruptive add-ons, our on-site team implemented them as controlled extensions of the existing architecture.
We expanded the MVI configuration, introduced new program feeds, and updated video/audio routing while maintaining stable live operations. Changes were implemented through structured patching, clear change control, and careful validation to ensure new outputs were correctly mapped, synchronised, and monitored, without interrupting ongoing sessions.
Delivering Confidence in Hybrid Interpretation at International Scale
The 4th International Congress for IndustriALL Global Union ran seamlessly, showcasing Congress Australia’s ability to combine remote interpretation with large-scale on-site distribution. Our team provided a flawless multilingual conference environment that performed smoothly under pressure, allowing the client to focus fully on the congress outcomes while delegates engaged confidently with every part of the program.
This event required a high level of technical expertise from our technicians, who adapted quickly to evolving requirements and maintained absolute stability across every room and session. The seamless opening address delivered by Prime Minister Anthony Albanese demonstrated the interpretation system's reliability and accuracy during the event’s most high-profile moments.
The client described this as the “smoothest” global congress they had delivered, highlighting both the quality of the technical setup and the on-site team's responsiveness. Notably, they remarked that it was the first time they “did not have to worry” about the interpretation or conferencing systems during the event.
