I take it that by "Indonesia" you mean one of the Indonesian islands nearer to Singapore. These would be Bintan and Batam. They are served by different ferry terminals.
If your husband is working in Bintan, he will be taking the ferry from the Tanah Merah terminal which is in the East Coast. In this case you should be looking at housing in and around Upper East Coast Road. You will have PLENTY of choices and be surrounded by expats. You also have the (not very good) beach at East Coast Parkway to avail of. You will have a choice of high rise condos
, low rise condo
s and terraced or semi-d or bungalow housing here.
If he is working in Batam, you will need to be near the Harbourfront Ferry Terminal which is slightly West of the Singapore's Central Business District. Again you will have quite a few condos to choose from and you'll also have plenty of expats around. The Caribbean is pretty nice and almost next to Harbourfront. Alternatively, if budget allows, you can rent a house or condo on Sentosa island and be VERY close to some nice (though artificial) beaches. A few minutes further West will take you to the Pasir Panjang area which houses and low rise condos aplenty.
Either way you should be fine.
