I'm only new to this forum, but can vouch for austarlabs.com. They haven't been around very long, and their product range is fairly limited (injectables only atm), but they've been getting solid reviews on other source forums. PED tests indicate dosing to be at least as strong as advertised, their communication is prompt, and shipping has been quick (AU domestic).
If anyone else knows of any AU domestic sources who supply orals, I'd be interested to hear about them.
