Looks to be a photo from a Boly Trail camera. You've been quite successful with it. @MartinPredavec - How did you manage to get so many shots of goannas walking past the camera? Did you drag a piece of meat along the ground or something?
@PatrickCampbell2 - No bait used with the camera. It's my lazy 'go to' spot to put the camera since its next to my house. It gets a good range of animals passing. It's next to a dam and with the house on one side and the track on the other it forms a corridor. The Boly trail camera has worked very well.
