Below is the output from a traceroute between me on Ihug Jetstart DSL

Is 126.96.36.199 an Ihug router or a Telecom router?
No. That is a RAN (Radius Access Node) within the telecom IPNet network.

Firstly, you can disregard how it is working right now. If you'd checked
the MOTD page, you'd see there are national traffic issues at the moment.
This is my real question... why is this such a big lag
between 6 & 7.
140ms seems to be very high? Is there some type of bandwidth gap
between Ihug and Global Gateway?
There isn't. Global Gateway isn't out normal national peering circuit.
Again, refer MOTD.
