Hi Franco,
I think what you have there is the droppings of a medium sized macropod like a wallaby or perhaps a pademelon. Looks grassy and is irregular in shape. I thought maybe bandicoot too, but it looks too grassy. But maybe look around for scratchings in the ground which might be evidence of bandicoots. Breaking some dry droppings open and see how digested the material is, and see if they look more like digested grass, leaves, fur, or generally indescribable mush.
It’s not a koala however, as koala droppings have a generally regular cylindrical shape, and if you broke them open, they have very fine evenly crushed leaf parts, and yes, they do smell eucalypty! Brushtail possum poo is similar to that of koalas but are more irregular and variable in shape and often have fur sticking out the end, and material is not as neatly/evenly digested as a koalas. See brushtail versus koala below.

I thought I had a photo of echidna poo, but I couldn’t find it, but basically it is about as long and a similar diameter as your thumb, is brown and hard when dry, like dry mud, and when you break it open there are little “glassy” looking bits of ant exoskeletons. See here for a pic->
