How do you raise your dough in cold seasons?
A non-exhaustive list of ways to get your bread to rise when it's cold includes:


Just let it rise slowly over a long period of time, which does give you good flavour but requires serious patience
Put it in the airing cupboard, assuming Australian houses have such things, but in the winter the hot water tank will keep it nice and warm
If it's still in the rising in the bowl phase rather than having been shaped, you can carefully put the bowl in a larger bowl of warm water (not too hot though or it'll go a bit mad)
Sometimes I can get away with putting the pan with the shaped bread ready for the oven over a large bowl or bucket of hot water
Put it in the oven with the pilot light on if your oven has a pilot light
Put it in the top oven with the door open while you're cooking something else in the bottom oven, if you have two ovens (careful though, this can get too hot depending on your oven)
