The Ashes leading wicket taker arrived back in Sydney for the scan on Wednesday still on crutches in an attempt to take pressure off his heel.
“If it is up to me I’m playing,” he said.
“But I think there’s a few other people in that conversation first.”
Starc, who has taken 19 wickets in the series, spent Ashes victory celebrations in the Perth dressing room on Tuesday not drinking and with his foot in a bucket of ice.
He is due to arrive in Melbourne on Friday but will be accompanied by Jackson Bird who looks likely to take his place if the left armer cannot be risked.
Meanwhile, former Aussie paceman Mitchell Johnson has called on his country to deliver another 5-0 series whitewash over the tourists.
“Going to the next test I think England will have to think about changes,” the 36-year-old said.
“I’m not sure if (paceman) Stuart Broad is up to it at the moment. There will be some question marks around him, (as) a senior player.
“(Opener) Alastair Cook is someone who I think has been thinking about retirement.
“I just wonder now with the scoreline being 3-0 whether that will take a bit of pressure off him and he’ll just go out there and score runs. I’m not sure.
“I think the scars are there from the last series.”
