Augustus has had a jump-out and a 1500m trial to prepare him for Saturday's return in which he will be ridden by Mark Zahra.
"Mark rode him the other day at Caulfield (Heath) and he liked what he felt," Maher said.
"I think Flemington will suit, a big, open galloping track. I think he will be a horse we will see more of in these better staying races."
Maher expects Augustus to have only a brief autumn campaign before concentrating on the spring and the Caulfield Cup-Lexus Melbourne Cup double.
"He'll probably have a couple of runs and whether he goes to Queensland, we'll work that out with the Australian Bloodstock boys, but he's impressed me with what I've seen," Maher said.
Desert Hero has only been seen once since his appearance at Randwick last April, finishing fourth in the 1500m trial at Caulfield Heath in which Augustus finished second.
Maher said Desert Hero was given an extended break after his Sydney outing and sent time in New Zealand.
"He's got a good solid base. He prepped up over in New Zealand," Maher said.
"He had a long break, which I think he needed and he's come up well also.
"He's been out of form for a little while, so he needs to find form, but looking at the way he is, he should hit the line well also."
