A demonstration was held on Saturday by more than 2000 people in Singapore to demand curbs on immigration.
The crowd at Speakers' Corner repeatedly chanted "We want change".
A government policy paper last month said the population could be between 6.5 - 6.9 million by 2030, with foreigners making up 45%.
Singapore's current population is 5.3 million.
"Save Singapore -- Say NO to 6.9 million," said a banner.
AAP reports protests are rare in Singapore, but foreigners are blamed for stealing jobs and straining housing, transport and medical services.
Organisers said the turnout shows people are no longer afraid to express opposition in a state known for strict social control and intolerance of dissent.
