The Malysia Digital Arrival Card (https://imigresen-online.imi.gov.my/mdac/main?registerMain) has a question requires one to specify the "Last Port of Embarkation". What would this be if I were to travel from Melbourne, Australia to KL with a connecting flight at Singapore (not going through immigration/ exiting the airport)? Thanks. The "contact us" link in MDAC does not appear to be working.
