The remains of a fair-haired girl, aged between two and four-years-old, were discovered in a suitcase next to a motorway in Adelaide earlier this month.
They were found alongside several items of clothing and a degraded quilt.
The girl is believed to have been killed at a different location at some time at least as long ago as the start of 2007, according to South Australian police.
The discovery has led to speculation that the body could be that of Madeleine McCann, who was aged three when she went missing from her family’s holiday apartment in Praia de Luz in the Algarve, Portugal, on 3rd May 2007.
The Met Police have said that they are "aware of reports" and have made contact with authorities, in a bid to investigate whether or not the remains could be those of the missing toddler.
A spokesman said: “We are aware of reports of the remains of a child having been found in South Australia and we have made contact with the Australian authorities.”
However, speaking at a parliamentary committee hearing, Australian police commissioner Grant Stevens said: “There is absolutely no evidence at this point in time that the child is Madeleine McCann.
“To suggest something like that at this point in time would purely be speculating to get attention.
“We are focusing our inquiries on South Australia but we would be considering any potential missing child.
"Until we ascertain the identity of the child we need to be open to all possibilities.”
