We had the building done about a year ago, unanimous consent and that $275/per rings a bell.
Previously a flakey FTTC service here, checking the telephony pit in the street when the covers were lifted, it was not entirely surprising, rats nest twist wiring and waterproofing covers left unattached. One of the techs did say in future fibre would be installed everywhere – and at no cost, but when or if that may actually occur, who knows.
Installation by contractors (2 days in a 5 storey small block here), approval by nbnco and switch on, took a week or two from memory. You save paying the fibre connection fee with the ISPs, as would happen with a house, some of them were extremely slow on offering fibre plans (database? not updated for months) and simpler to just change provider.
Unless it’s a big complex, the 3 months may refer to the time it takes for the preliminary plan to be produced, which lays out proposed various exterior fibre connection terminals and cable/conduit runs and the internal NTD in your flat, all of which you have a say on location, must be near a power point though. It was unnecessary in the end (safe work practices at height on a ladder) we insisted all cabling went up the cavity or in the subfloors from the building pit – construction of the building will dictate what’s possible there however.
