When buying a separate Pokéwalker, does it have to be from your country

1. • Yes, they should work with your TV, as both the UK and the AUS region use the PAL system, however, be aware that you might need to buy new power cords over there.

   • As proper broadband uses CAT5 Cables worldwide, a normal plug & play broadband connection should always work. (also, wireless also uses the same basic system worldwide, so no problems there too.)

2. I sadly wasn't able to find a conclusive answer for this question, however, my tentative guess would be that it is possible.

3. • As far as I know, (and a Google Search seems to agree) prices of games in Australia are more expensive, and with the low £, it might be profitable to stocking up games. (your best bet is to do some price comparison on the games you think on stocking up.)

   • Be aware however, if you think about trading-in games in Australia that this can be slightly difficult for UK games dependant on Game and Retailer. (luckily no language barrier, just ratings)

   • Also, be aware of the Australian Censor when Importing Certain Games

4. Do what you like the best, weither it is gaming or enjoying the climate, just don't overdo it.

5. (BONUS) Games bought Down Under should usually also work on your system, as both Europe and Australia are usually considered to be in the same zone (related to point 1)

As far as I know all PS3 games are infact region free. The same cannot be said about Blu-Ray movies though.

and of course there's this question as pointed out by Colin.

However most of these are only forum posts. If I get chance will have a good search for some concrete evidence from Sony.

Happy gaming :)
