Saw total of 4 individual toads, only got photos of 3. This is one of them. Definitely nocturnal as they seemed to be everywhere tonight and normally I only see them during the day if I have disturbed them. One of them showing the unique colouring (especially of the eyes) and darker body. I do think now though that it is also a common toad just different colouration. I checked AmphibiaWeb and some of the pictures looks like this different coloured one.
