Okay, just that it was a very sweet butternut pumpkin so I have dried out the seeds and will plant in September. Thanks for the advice everyone, it is always great to get something for next to nothing. Happy gardening!

The monthly calendar tells you when to plant.

Pumpkins need to be planted as soon as possible after the last frost as they need a long growing time. Probably best not to plant after the end of the year. (Welcome back John)

Your pumpkins might not be pollinated. Pumpkins, courgettes etc need bees to pollinate them. You can hand pollinate either with a soft artist's brush or by picking the male flower (no miniature pumpkin behind flower) and brushing the pollen onto the female flower stamens . Have a look at this https://www.thekitchn.com/summer-gardening-handpollinati-57513

It's early Autumn and I've just discovered a lot of pumpkin vine volunteers in my top garden. Should I let them go or pull out now, given there is not enough time for them to set fruit before Winter? I live in a warm temperate area above Sydney.

I have been hunting for ages for the seeds of the Iron bark pumpkin, and so far have not been successful. Does anyone know where I can get them? They are a beautiful dry excellent roaster, and make great pumpkin wine! I also am growing something that lookes like a Jap, but has the shape of a butternut. They were self sown, too.
