Last year in Sydney was the strongest performing CBD market nationwide with office rents rising 17.6%. JLL research says there is the potential for a strong rental growth in 2017-18 as well in Sydney.
Vacancy also increased marginally in the fourth quarter of 2016 to 7.7% after International Towers Sydney reached practical completion.
Mr Kernaghan explained: "The performance of the Sydney CBD office market should be put in context – 2016 was largest year for completions since 1992 and it had no impact on the headline vacancy rate over the year.
"Competition for space was generated by organic growth across a range of industry sectors and the displacement of tenants from Sydney Metro and residential conversion.
“The next wave of displacement will be generated by tenants vacating 50 Bridge Street."
Since the start of the rental upturn in the fourth quarter of 2013, the Sydney CBD has recorded a 32.5% growth in prime gross effective rents.
