I know this is the Bali forum but many people go to both so I hope this post is excused....
For anyone interested there is an article in the Weekend Australian Magazine about Australians buying property in Lombok and the pitfalls and scams they have experienced. The article is called Heaven Can Wait".
The Magazine can be accessed online for anyone interested.
I'll try to post the link below otherwise it is easily found on google...
