Wi-fi has no effect on your call plan whatsoever, and nor will you be charged by your carrier for using it. That is the whole idea of it.
The 2gb download limit you have will be for connecting to telstra hotspots i imagine. Rather than connecting to the wi-fi in a bar, or a hotel, or even in your home. In these place, by using wi-fi you are using their internet connection, not your own.
