Maybe Chorus can earn more money by forcing the ISPs to install more/bigger handovers than the pricing difference between 100 and gigabit connections to avoid contention after the upgrade to 300Mbps
Unlikely. Prices have come down for 100G since it initially came out and they now do Single port offerings rather than 1+1 for it.

Bit of a mixed bag overall, with Tail Extension Services it allows a single high capacity handover to cover the entire country for fibre which can bring down the cost for smaller providers (better for those who have a large customer base in a single region) but can be a balancing act for actual viability of ordering when you consider the equipment requirements to terminate to it and the structure of the network for the average small provider. Port availability for 10g and even 100g handovers has been quite spotty for a while now and Chorus are quietly trying to nudge providers out of the main Spark exchanges everyone has been installing to.
