A small program to check your traffic usage. Works with many ISPs: ACSOnline, Actrix, BorderNET, Farmside, InSPire, Maxnet, Orcon, Paradise, Quicksilver, Slingshot, Snap, Telecom/Xtra, TelstraClear, Vodafone/ihug, Woosh, WorldNet, Xnet and Zelan. If it doesn't support your ISP then just ask.

Download v1.86 for Windows XP/Vista/7. Also works perfectly under linux using Wine. For Mac, try Crossover (untested, but it should work).

Alternative download, without installer here (just unzip it to a directory of your choice).
