The average costs per office workstation in Sydney rose by 20 per cent compared to 2008, according to property research firm DTZ.
Meanwhile, the cost per office workstation in Brisbane also increased, rising by five per cent over the 12-month period.
This resulted in Sydney and Brisbane moving from 45th to 23rd and 38th to 29th respectively on the Global Occupancy Costs ranking table.
The increases in costs were also in contrast to the four per cent decline in average costs recorded globally.
Meanwhile, according to the Frontier Centre for Public Policy (FCPP) Housing Affordability Survey, residential Australian properties in Sydney, the Sunshine Coast, Darwin and the Gold Coast are among the most unaffordable for locals in the world.
All four regions made the top five on the list of most unaffordable properties, topped only by Vancouver, Canada.
