Sydney region costs in US$:
If at any moment a T2 instance does not need all of the CPU credits it receives, it stores the unused credits in its CPU credit balance for up to 24 hours. For example, if a t2.small had a CPU utilization of 5% for an hour, it would have used 3 CPU credits, but it would have earned 12 CPU credits during the hour, so the difference of 9 CPU credits would be added to the CPU credit balance. Credits earned 24 hours ago will expire, and any expired credits are removed from the CPU credit balance at that time. This means that if the amount of credits expired is greater than those earned, the credit balance will go down. If the baseline CPU performance isn't being used, the credit balance will eventually stop its decline and potentially grow, depending on how much CPU is needed in steady state.
The T2 credit system is designed so that if your workload doesn't on average use more than 20% of a single core over the course of 24 hours, for example, then a t2.small is a good fit. The same thing can be said for the t2.micro (10% of single core performance) and t2.medium (40% of single core performance). If your instance consistently does not maintain a positive CPU credit balance, then larger T2 size or a fixed performance instance is recommended.
See Cloudwatch metric CPUCreditBalance for current credit balance.
As a side note it appears T2 instances have good networking performance. This AWS forum post shows t2.medium with iperf performance of 4.48 Gb/sec.
