The only thing that is stopping us from having Google Cloud is lack of an Australian data centre. I'd love to be on Google Cloud, but requirements prevent us from doing so unfortunately :-/
Latency is a huge one for AU. With AWS in SYD you can easily cover BNE, SYD, MEL and even AKL. The difference from SIN or TPE is very noticeable. SYD to PER and SIN to PER is negligible.
