This is only a conjecture but the police seem to be working on the idea that the person responsible for the disappearance of Mr Hill and Ms Clay drove out of the wilderness and joined the Dargo High Plains Road.
McMillans Road is just one of a number of roads coming out of the Grant wilderness area that join the Dargo High Plains Road. The distance from McMillans Road to Mt Hotham, is approximately 50 km. The 4WD and trainer were photographed at Mt Hotham.
If one looks at the photo, below, it appears that the shadows are running from right to left. Given that we drive on the left here in Oz, and the photo was reportedly taken around 6.00 am, then it is a fair bet that the vehicle is going up the mountain not down.
Recall that (my friend's time line again),
April 14, 2021: Information leads detectives to Mount Hotham, where two shovels and reportedly, other items are found during a search in a small area of bushland next to the
Great Alpine Road.
This suggests that the vehicle went up from the MacMillan road area to mt hotham and then down through Dinner Plain, Cobungra to Omea (assuming the driver stuck to the highway).
Down this road are multiple cctv installations, phone masts and so on.
[Note also in the photo below that the trailer appears to have a licence plate. I understand that in Victoria a trailer takes to plate of the vehicle towing it. There is no indication when the photo came into the possession of the police or when they realised its significance. But in April this year they were still speaking of a "mystery white" ute, however, they spoke to Mr Lynn last year.]
