Via OzBargain. For those travelling to Singapore.
Basically for SGD $32 you get 2GB per day at 4G speed and valid in 18 countries (refer to image for details) for 15 days. It's absolute treat for travellers to the included countries and transiting via Singapore. SIMs can be purchased at UOB money exchange outlets in transit area.
There is a similar $18 option available as well for those visiting upto 5 days.
FYI SGD $32 = ~ NZD $34.
Good deal!
If you're visiting Singapore only (as I am in a couple of weeks and so have been researching SIM card options), it may be a better deal to go with the Singtel hi!Tourist $15 SIM Card offer.
It offers:
100GB data
Unlimited free access to Facebook, WhatsApp, LINE, WeChat.
500 minutes local calls
100 local SMS
30 minutes of international calls
and is valid for 7 days.

The Starhub deal definitely looks better for roaming though.
