There may be opportunities in some other countries, but my guide is specifically for Matched Betting in the UK only. What you need to matched bet is three things. Firstly betting websites. Secondly, you need offers, odds boosts and various other types of incentives from the betting sites. Then importantly, you need an exchange to lay your bets. If you have these three things, you can matched bet in other countries too.
