A $7.4 billion building boom in office towers, apartments and hotels in central Melbourne is raising fears the city may become a victim of its own success, with oversupply putting pressure on vacancy, rents and values.
Gross supply will increase by 170,000 square metres in 2019 and by 290,000 square metres in 2020. The 20-year average gross supply in Melbourne CBD is 120,000 sqm annually.
