The granting of visit passes is determined by the Immigrations and Checkpoints Authority (ICA) officers at the point of entry.
Useful information that you should know before arriving or departing Singapore can be found here.
Although a visa is not required for Australian citizens for a stay of up to 90 days, visitors are advised to check their passports for the arrival endorsement and take note of the number of stay days given before leaving the checkpoint.
All visitors on visit passes are not permitted to engage in any form of business, profession, occupation or paid employment while in Singapore.
Visitors are also reminded that it is a punishable offence to overstay beyond the number of days given. If there is a need to stay beyond the period granted, visitors may apply for an extension of stay online via the “Apply for Extension of Short-Term Visit Pass” or at the Visitors Services Centre, 4th storey, ICA Building, 10 Kallang Road before the visit pass expires. Application for extension of stay is subject to approval. (Source:Immigration & Checkpoints Authority).
