hello there, I don't know much about the PR industry.
All i can say is have that our Kiwi's *CAN DO* attitude...jump in and give it a go!
It's not too bad here , the *BIG* city itself you are thinking of isn't that *BIG*. Singapore is I dont know 1/7th of our Kiwiland? ok they have 7 times as many people as ours, but hey it's just PEOPLE right..
Beside , this is rather modernised/westernised. I wouldn't be surprised if you end up working for a Kiwi/Aussi/English/American/Irish boss ..my understanding is PR industry is pretty hot here to...i mean in general Singapore economy is HOT and job market is HOT too...
Try google Singapore websites for job search , have a look at your area, do a bit of research...
There's a kiwi/aussi club for support too http://www.anza.org.sg/
and plenty of us around
NOT scary at all
