Singapore will allow quarantine-free entry to travellers vaccinated against Covid-19 from Australia and Switzerland from Nov 8, the city-state's aviation regulator said.

Singapore is slowly reopening its borders and has expanded quarantine-free travel to nearly a dozen countries, including Germany, Canada, France, Britain and the United States, under its Vaccinated Travel Lanes (VTL) programme, Reuters reported.

Visitors can travel to Singapore under the programme if they have been fully vaccinated and tested negative in Covid-19 tests.
