Contract is over and phone is still running fine.
Am nearly always around wifi so 3G usage is minimal.
Call everyone via Skype/Viber so don't need calls.
Nearly everyone has iMessage/Facebook so free messaging.
Amaysim resell Optus so reception should be pretty good?

$100/10 GB/365 day expiry.
PAYG calls/sms
This seems the best option I could find. 10GB should last quite a while and I still have the ability to call or SMS normally if needed.
A block of data is much better than 1GB/month style because most of the time it'll only be 1-200MB, and when away it can easily be 4-5-6GB.
Any catches I've missed or it's one of the best options out there?

Betterlife are also a reseller of Optus and are on 4G with incredible deals if you have a Healthcare Card, I just signed up to the $33 without HCC and they charged me $39/month without contract or any additional fees.
I'll be getting my SIM card this week with service up next week.
Based on reviews by users it seems to be a really good deal
