Peter Stamp, AARNet was one of their engineers. And, Scott Calwell (Vocus), and Mark Treacy. They worked on the X terminal and the i960 based network devices, and the architecture of the access-1 network.
I'd forgotten something else till I read one of their work bios: I'd just thought OzE bought AOne for the corporate/govt customers (who included Coles Myer and Aus Post), but they also bought it because the AOne network was a more robust network than OzE's. Those Labtam guys were just very good engineers.
Edit: Oh you were there too. Awesome. Malcolm Rd represent.
