A large sinkhole has emerged at a sporting field in Melbourne's north-east, close to where tunnel boring machines are constructing the $26bn North East Link project.

Footage shows the large hole at A J Burkitt oval in Heidelberg. It is about five metres deep and measures about eight metres by eight metres, according to the State Emergency Service.
