Australia - Seeing IPv6 Akamai get sent 150ms away

Obligatory diag results: https://nextdns.io/diag/7f474e10-70f5-11eb-975a-95872b152f72

A friend and I have noticed pretty crap performance over the last few weeks and I have today noticed Akamai IPv6 traffic being sent internationally rather than sticking around in Australia.

Here's a difference between ISP DNS and nextdns for a pretty popular website here in Australia.
