I stand (OK, sit) corrected. OpenTRAC was not from Australia. SARTrack 
is from New Zealand and is alive and well and has developed into a 
significant resource management suite.

It looks like this may be something like the OP was looking for.

It looks like OpenTRAC may have been an idea to "fix" APRS as a lot of 
what it wanted to accomplish is in today's APRS protocol. It looks like 
it was kind of a "flash-in-the-pan" thing and has fallen by the wayside.
