They also say "despite the decision to invest in NAT technology, Aussie Broadband has also decided it needs to speed up its IPv6 rollout".

Despite IPv6, you still need CGNAT, because not every site/service is available over IPv6. It's fine as long as it's a stopgap, not the main solution.

NAT64 is better than CG-NAT (single NAT vs double NAT) and they both solve the same problem.

At what point will NAT no longer be required? Is IPv6 really seen as a successor or just a supplement to IPv4?

- v4<->v4 increasingly requires NAT due to scarcity

- v6<->v6 does not require NAT

- v6<->v4 requires NAT but does not require your v6 device also have a v4 address

Until the v6<->v4 is no longer needed you will always have some form of NAT as there aren't enough addresses to give everyone a v4.

At least in gaming, ipv6 causes issues especially together with NAT or dual stack lite...
