Perisher Skitube construction

The Transfield/Kumagai Joint Venture constructed the Perisher Blue Skitube to transport persons by train from the bottom of the Snowy Valley to the Blue Cow snowfields as well as the Perisher Blue snowfields. The Joint venture commissioned Illawarra Communications to provide the communications for the construction period to ensure safety for their personnel with reliable communications during the dangerous construction time.
By the use of repeaters linked to an antenna cable (Radiax) through the tunnel the Joint Venture was able to communicate to the areas they needed to both inside the tunnel as well as to the surface.

Sydney Harbour Tunnel construction

The Thiess/Kumagai Joint venture constructed the Sydney Harbour tunnel to provide another means of access to and from the Sydney CBD and reduce the traffic congestion on the Harbour Bridge.
The first stage for this construction started in Wollongong in 19 with the construction and casting of the individual tunnel sections that would eventually be sealed together on the floor of Sydney Harbour to form the tunnel. This part of the construction was carried out by Transfield who commissioned Illawarra Communications to provide reliable communications around the casting basin site in Wollongong for their personnel with portable radios to assist in the safety and productivity of the site personnel.

The next stage was to transport the huge tunnel sections out of Wollongong to Sydney Harbour. This was accomplished by having each end of the tunnel sections sealed water tight. The casting basin was then flooded so the sections were afloat. Each section was then floated out of the Wollongong Harbour one by one up the coast and into Sydney Harbour. Once again Illawarra Communications were given the responsibility to provide reliable communications for the trip.

The final stage to the construction was the positioning of the tunnel sections on the floor of the harbour so they formed the full one kilometre tunnel across the harbour. Radio Communication was again required from the surface to the inside of the tunnel sections as they were put in place, sealed section to section and finally opened at each end of the tunnel. With Illawarra Communications expertise radio communications was maintained all the while from surface to in the tunnel during the whole construction stage.
