I used Eenees flushable liners when on holiday in Malaysia.
Then again, I could've gotten away without them because it is customary to have a LS-like toilet squirter next to most toilets, including public loos (they don't provide toilet paper in most places though)
Do note though that not all disposable liners are flushable!
ETA: I asked Dad to buy me 3 toilet squirters from Malaysia, works a treat! And much cheaper than those you buy here: with the Malaysian exchange rate, you can get them for around AU$10-15 each.
You would still need to buy the t-joint from a hardware store though. We didn't as we built this house, and added on extra ministops next to each toilet
