Australia Camping: Water in my tent in the morning?

[AzrinSani]

I went camping in Australia a couple of moonths back during summer. I realize that everyday in the morning when we wake up there is a lot of water inside tent. There was no rain that night. I also thought that maybe my tent was leaking but nope, it wasn't

Is this something normal? Can this be avoided by using better tents? I have searched the internet and couldn't find anything related.

Thanks for any help
