The northern most station on the new link will be formed using bottom up construction with 30m deep diaphragm wall panels forming the retaining structure.
Victoria government minister for public transport Jacinta Allan said that 330,000t of soil will be excavated to form the 20m deep new station which will have platforms 225m long.
The new station, which is one of five on the AUS$11bn (£6bn) project, is expected to be the main driver in regenerating a former industrial area into a new suburb.
Work to install 40m long piles to support the station structures is also expected to start this month. Diaphragm walling work is expected to be completed later this year.
Two of the tunnel boring machines that will drive the twin bore tunnel will be launched from the site and the new metro link is expected to open in 2025.
