O2 in the UK has released their pre-paid data pricing now:
500MB + unlimited Wi-Fi £2 a day
1GB + unlimited Wi-Fi £10 a month (30 days), recurring
3GB + unlimited Wi-Fi £15 a month (30 days), recurring
(wi-fi is with "The Cloud" or "BT-Openzone". Both these have pretty good wireless networks in major places such as London CIty, airports, large train stations, pubs, restaurants etc)
So the prices are fairly similar to the Australian data prices, although with free wi-fi included.
