Both are actually in Indonesian waters.
Perhaps you mixed up Lombok with Lembogan??
Anyway, there are a few Indonesian Islands that are accessible from Bali, but all I would say will require a couple of days minimum from Kuta/Legian as trips North to Menjangan require that as do trips to Lembongan if the trip is to be at all meaningful.
The Gillies certainly require a good 2 - 3 days minimum.
