A fellow Aussie currently in China, a Trojan [0] server has been working fine for the last week I've been here. I've got it hosted through a VPS (smaller provider) in LA. While it's a bit of a pain to setup, reliability has been pretty decent (with occasional? short breaks) and definitely useable - my laptop is connected 24/7 and I can access the unfiltered web, including video, just fine. V2ray also supposedly works quite well, but I haven't looked into it.
