An already congested Green Square is likely to get more populated by the end of 2030, new City of Sydney projections revealed.

According to the Sydney Morning Herald, the suburb, which is expected to house around 61,000 people in the coming 15 years, has its population up from 54,000 people as previously thought. This growing population of the 278-hectare area to the south of Sydney's central business district has sparked concerns about the congestion issues.

The expected population of indicates that it will be double the current population of Pyrmont, considered to be Australia’s densest suburb with 15,000 people living per square kilometre. Green Square council said the place attracts developers due its excellent design process. And if developers deliver higher quality projects, they are given an extra 10 percent of floor space as bonus.

"This new data on Green Square's rapid evolution illustrates the community's confidence in what is one of the biggest urban renewal projects in the country," Sydney's Lord Mayor Clover Moore said. He also emphasised on the need for more schools and transport in Green Square, which was investing nearly AU$540 million on new facilities.

"The City has already invested $40 million to secure most of a transport corridor and we are now working with Transport for NSW to assess funding models, look at route options and undertake other work required to progress the development of a new network," Moore added.

However, Darren Jenkins, the president of the Friends of Erskineville, has expressed his frustration over the government’s failure to meet the growing infrastructural needs of the area. He said that the sharp increase of 7,000 people should surprise the state government or the council, adding that it was “inevitable that developers are going to try to get as many apartments into the space as they possibly can.”

Labor councillor on the City of Sydney, Linda Scott, said: "I have met with endless streams of residents who are rightly very concerned about the lack of transport infrastructure in the area, given the density of development," she said. "The state government has provided no solution to what is clearly a huge problem – and to be clear, the council hasn't done enough either."

Similarly, internationally renowned Danish architect Jan Gehl has also expressed his concern over the population increase. "It is quite high and it is quite dense and it will be somewhat overshadowed in many places, so it is extremely important that the spaces between the buildings become very acceptable, very attractive," Gehl told Domain.

Meanwhile, 10,000 of Green Square dwellings are being re-constructed at the moment.
