Now a four channel VHF site (3 voice + 1 data)  - three frequencies deleted from the site in 2004 due to a) change of ownership and  b) the closure of the backlot The only VHF Motorola Type 2 system in Sydney.
The studio has become popular with US film producers due to the weakness of the australian currency.  As australian film crews have similar skill levels to their overseas counterparts effectively this
means that film costs are a lot less than in Hollywood ie bigger profits  eg Matrix I and II and Star Wars II and III were filmed at these studios.
