"The foot won't rule me out for the rest of summer so no point doubling up and missing extra time with surgery," Starc said in Adelaide.
"The ankle is going pretty well. I'm not too worried about how that's going to be when my foot [injury heals].
"It probably will do it a bit of good if I keep that range in there. It's just about trying to get that bone in my foot right and ... see how it is when the boot finally comes off."
Starc was unsure when he'd play for Australia again.
"It depends on how it heals ... there's no point putting a timestamp on it until the bone heals," he said.
The express paceman was also vague when asked whether the injury was related to his ongoing ankle issue.
"It's probably something you can ask the medical staff," he said.
Cricket Australia say its medicos are still assessing Starc's wrecked right foot and he will play no part in Australia's upcoming three-test series against the West Indies.
The 25-year-old has been bowling under duress for most of the year.
However, he managed to deliver career-best form in that stretch and became the side's spearhead when Mitchell Johnson retired during the second test against NZ.
Starc was trying to stay upbeat after the setback.
"It's frustrating," he said. "It [the ankle] has been going okay ... it hasn't stopped me bowling.
"I had a couple more cortisones after Perth test. It has been managed quite well. Now the foot has popped ... but there's not much I can do about it."
Starc admitted he was surprised to be sent out in a thrilling finish to the pink-ball clash with NZ on Sunday night.
"I'd like to ask Steve Smith the same question," he said. "The spinners were on, so he asked if I'd go out there and have a slog. I thought that might change when they took the spinner off but it ended up that I went out there."
