Owners’ corporation as Internet Service Provider?

I’m in a block of 40 units in inner-city Sydney. Our SC has been looking into connecting the building to a high-speed wholesale internet connection (1Gbps fibre) and connecting up all units to share the connection using an internal (common-property) network. In principle we can get gigabit speed to each unit at a very good price.

However, the bulk of the costs are fixed, so the average cost per unit is attractive ($60/month) if all units use it, but it gets more expensive if the costs are divided among fewer people. Also, it seems unfair to pay the costs out of levies if some lots do not join in and gain the benefit.

As an alternative to funding from levies we could make a 143(2) by-law and sign up units to pay for the service separately. But as half the units are tenanted, getting owners on board could be a challenge. We would also have to set up a system for billing (although perhaps our strata managers could help here, I haven’t asked).

Does anyone have any advice, if not with shared internet, experience with shared utilities of any kind that are billed separately to levies?

Thanks in advance!
