"When the race was run the way it was, it was brutally run, and with a horse like Light Infantry Man winning it, sitting second, it says a lot about the race shape," Turnbull said.
"For him, who was back, no headgear, floating along, he just never got involved.
"His splits late were positive enough, but he should have done something because he did nothing for the first three-quarters.
"He's had a couple of good gallops, he gets on the bigger track, the mile again, headgear on, there's a lot more going his way this week."
Turnbull said Willydoit had been one of the better staying three-year-olds having also finished fourth in the Australian Derby (2400m) at Randwick last autumn, but as a spring four-year-old the stable decided to chase spring riches.
It included finishing ninth in The Golden Eagle after running seventh in the Alan Brown Stakes.
"He was a dominant staying three-year-old, but he's not slow, so coming to Sydney last campaign, with the weights, we were willing to try him in the big features which didn't work," Turnbull said.
"A prep on, we know a bit more about him and I think 2000 (metres) will be his go.
