Myself (26/m) and my girlfriend (28/f) will be moving over to Singapore in August from London. I'll be working in Financial Services and she is a teacher, so will be working for an International School.
I just had a quick query regarding renting and opening a bank account. From what I can see, you need a passport and proof of address (two utility bills) to open a bank account, which is fine. However would you not need a SG bank account in order to rent a place? Just trying to work out what comes first!

We'd also be keen to speak/meet with any other people relocating, or who have recently moved to SG.
Thanks
