They haven't been pollinated. Try transferring pollen from male flower to female flower.

It is about 4 months too late by the guide here. It is not the temps now but what they will be in 4-5months time when the pumpkin are suppose to mature.

Hi there, I am in Sthn Gold Coast. Am I able to plant a butternut pumpkin in a very large pot (for root growth) and then let the vine trail over into the garden. My soil isn't very good, by using a pot I can buy good quality soil / potting mix. Would this work? Thank you, Sam.

Yes it would work - need to water regularly and also fertiliser now and again. Amazing what a little compost and fertiliser can do to poor soil.
