Please Refer to my earlier comments in the other 20 Sept 2020 Posting for this Site / sighting. These are some additional photos which may be helpful ? if any other species ? are in these pics ....
Max perhaps it would be better to load up photos individually unless you take photos of one specimen (such as a close-up and overview). I know it is time-consuming....
The dark brown frog, show on its own in the third image is Uperoleia laevigata. The larger frog in the second image along with Uperoleia is Litoria, possibly verreauxii but I would have liked a peek at the hind leg colours.
