Regarding, Changing over the funds online to Australian $, to UK Pounds, but again, most sites play in US $ Anyway, Pokerstars, FullTilt, Ipoker etc.
Regarding live cash games, most evenings and weekends you will get them all over London, Luton (Short train journy) and you can also get a cash game usually from about lunch time at the Victoria (Where the EPT London is played), dont really know about stakes, or level or skill, as have never really got involved as I have been on my lunch break etc, but there usually sitting with a few K in front of them.
Home games, errrr I dont know of any regular ones myself, in London, but there are a couple of month, locally to myself, so I sure there are some, maybe an idea to look at
www.gumtree.com or just get him to talk to people when he is over here.
Living wise, Getting around London is cheap, bus or tube, maximum of about £40-£60 a month, etc and black cabs are not highly expensive, £2.20 to get in compared to £4.40 where I live. If he is going to live in a one bedroom flat alone, your looking at between £600-£900 a month, and that is not even the top end market, If he is going to flat share, which alot of Aussies do when they come over, your looking at between £300-£600 a month.
For a king of idea of quality and price etc

But that is living the way i live...
