I just walked past an estate agents and saw a 4 bed house for £3000k a month! So it will vary but hopefully £2k is more like it for you. Re the commute, you can get the Overground from Peckham Rye or Denmark Hill to Shoreditch High Street and then it isn't that far of a walk to Old Street. (Or as said, London Bridge then Northern Line).
Shopping can really vary as ours has shot up now we're all at home a lot more
but we can probably lower eating out budget at the same time. Family of 4 here and weekly shop can vary from £80 to £120 depending (occasionally buy kids clothes in supermarket so spikes up the cost).
Childcare is pricey, you can try so may different options though to work out what is best. Childminder, Nursery, Nanny (or Nanny share to lower costs). We started with a childminder then nursery and it gets steadily cheaper as they get older so something to think about that you might have a larger hit initially. Also once they're in school that is a big chunk of spend you lose so it's only for a few years.
Car - that is totally down to your lifestyle. Ours is mostly used for weekly shop and visits to parents (parent visits would be so much effort and longer by public transport). Prior to the car I used to have a pull along trolley and get the bus home from the supermarket so it's possible (but wasn't shopping for 4 then!).
Houses - we are SE15 but 30 seconds from SE22 so you can try to get clever by being close to where you want but just outside. If you join "East Dulwich Mums" on Facebook you occasionally see people putting their properties on there before trying estate agents so you never know you could get lucky.
From what I hear from friends in Oz it's pretty expensive there so hopefully you'll find you're going in the right direction!
