QANTAS A330s loss of separation over Adelaide

Hi everyone
Does anyone know anything about the loss of separation incidence between two Qantas A330s over Adelaide today?
Here is a link to the news article: mobile.abc.net.au/news/2013-09-2 … ht/4971478

Would the instrument that alerted the pilots to the decreasing separation in this case be the TCAS or would they use something different on the A330?

Just interested, as the Air Crash Investigations television program earlier this week highlighted an incident several years ago where one pilot followed the TCAS instruction while the other obeyed the ATC, resulting in a collision. The safety recommendation following that incident was that pilots must always follow the TCAS instructions when it gives a warning, as the natural inclination is to respond to the human direction.
Sounds like both pilots must have obeyed their instruments today. :smiley:
