As far as I know, there is no Global Entry kiosk at immigration at AUS. However, there are now several daily international flights to AUS, including the BA flight from LHR.

I had heard rumours that GE kiosks were being installed in AUS, but I haven't seen any official press release indicating that GE was being rolled out there. Does anyone else know anything? I'm flying to AUS in August and would love to not have to wait in a massive queue.
