It would seem to be an ATC issued from the facts posted, BTW it was a military target tower rather than military metal, namely a westwind. Both aircraft were assigned the same altitude and lost both vertical and lateral separation, the ATSB site is more factual:


Investigation: AO-2011-011 - Boeing 737-7Q8, VH-VBK and Israel Aircraft Industries, VH-AJG, 22 km SM Williamtown Aerodrome, NSW, 2 February 2011

Generally Jet traffic for RPT movements are always under positive ATC control, especially in a control zone such as NTL, the only exceptions are the Concorde which flew too high and jets on descent into regional airports where control zones are not active.

Separation reduced to 400 feet vertical and 0.7nm lateral.

That is pretty close,but I have no doubt that the ATSB will conduct a full investigation.

There seem to have been a few ATC issues over the last year.

In this case it's Military ATC adding to the numbers.

The report is out and it was very much an ATC issue:

The investigation identified a series of errors by the Williamtown Approach controllers involving separation assurance, coordination and communication, and compromised separation recovery.
The investigation also identified three safety issues. The DoD advised that they reviewed and amended Williamtown procedures, introduced compromised separation recovery techniques training and trialled use of the conflict alerting function in the Australian Defence Air Traffic System at Williamtown.
