Don't forget the Royal Adelaide Show starts next Friday; it seems it's on over two weekends this year. Cheap tickets on Wednesday and Thursday if you arrive before 1pm and some super packages available pre-show from Foodland/IGA or through the website (probably incur a booking fee with that though!).
If you're new to Adelaide it's worth a day out - especially the Showbag Pavillion (a real Australian "thing") but be warned, it's not cheap and since our first experience two years ago I've learnt to save for the day. This year our 10 cents cans/cartons/bottles are funding the children's showbags.
