Properly set up incubators should never have condensation form droplets on the tub lids. Iit is very well known that water drops damages/kills soft-shelled eggs by blocking the pores used to exchange moisture and/or gasses. There are a number of incubation mediums available, the most common are: Perlite, Vermiculite, Sphagnum moss. The over water technique seems to be really gaining popularity amongst experienced breeders, when done correctly it seems to be a very successful way to incubate reptile eggs. The eggs pics you have posted are Christinus marmoratus, they lay hard-shelled eggs (only a handful of Aussie lizard genus's lay eggs like this) that do not react the same way as they do not absorb or loose moisture like soft-shelled eggs.
