Agree...most likely small croc. As Tman said, they are known to be at Tembe

My first impression is that it appears to be a smallish crocodile for the following two reasons:

1. The tail appears to be flat and heavy where as the monitor or the leguan lizards have round tails that taper off to a thin point at the end

2. The colour to me also resembles a croc more than a lizard

It came out of the watering hole...could it be a crocodile?

My first thought was that it would be a monitor lizard..but then I thought it looked like a small croc.  Do they have croc there?..I see T'man said he's seen them there before so that's what I'd say..a croc

My money would be on a monitor lizard.

I didn't even think of that. I went through the animal database for mammals and the closest thing I saw was a mongoose. It definitely moves more like a croc though. Thanks!

It appears to be a crocodile to me.  We have seen it in the past but was very blurry and further away so that is a good shot of it here.
