Did you test any providers who don't sell unlimited data plans? A few RSPs (e.g. AussieBroadband) stake their reputation on excellent performance.
You can easily calculate the maximum RSP spend on CVC by using the NBNCo wholesale price list. The basic calculation is: Maximum CVC spend equals retail plan minus 1/11 for GST minus AVC charge.
Of course this doesn't take into consideration the RSP's other costs (backhaul, support, sales, profit margin, etc).
At that point it becomes clear that only a few users sharing your PoI who use their connections heavily will cause peak period congestion.
