Which version of PON are Chorus using, GPON or APON? If APON 1Gb bursting would cause problems, if GPON, correct me if I'm wrong, but doesn't it only allow up to 2.4Gbps or something shared, or it's it per fibre?

What's the lowest latency people experience on a 30/10 plan? I'd be happy with a 10Mb upstream path. I wonder what the final upstream latency result will be when everyone in the neighbourhood is fibre and how  TDMA comes in to play.

Talking about connection vs rate limit, I agree 100 or 1Gbps makes no real difference to a 30Mbps plan.

In the old days when DSL first arrived I had the 128K plan, but I was much happier to have the full line rate connection speed as it meant even though I had 128Kb limit, my latency below 128K was as good as the connection speed's latency, which was extremely important for real-time audio for me.

I'm just glad to see we're finally going to get at least 10Mbps upstream fibre in the home. As much as I love the idea of faster downloads, it's about time the focus is on how to sell and create new business to the world over fibre at home, rather than being bigger consumers. It's usually a garage somewhere where it all starts.

The wholesale service generally used for residential connections is called Bitstream 2.

Chorus is just one LFC (the one with the most coverage areas though).

The service descriptions for the different LFC's services are here: 

The "Service Level Terms" for the connection from your house to the ISP depends on the wholesale service variant being used and the LFC.

If you want the cliff notes version: regular traffic on a residential connection is best effort with no gaurantee of reliability of performance. High priority tagged traffic has a CIR of 2.5Mbit and minimum latency levels.

Also after it gets to your ISP's network whatever contention/congestion level applies is controlled by your ISP and is private/confidential to the ISP, so therefore another issue entirely.
