They can't sell a 1gig plan without a gig of backhaul which current costs more than $1,400 a month. With a 20:1 contention ratio, the link from the NBN POI to the ISP is $70/mo. That means an ISP needs to have at least 20 willing to sign up in the same area before it is economical to turn it on.
What I would like to see is the ISPs use the 1gig NBN plan but offer something smaller like 233/100 and raise it as they add capacity to their backhaul from the NBN but I don't think they can offer that.
