UK Citizen Obtaining Chinese Visa in Australia

Hi
Myself and my partner will be departing the UK in September to do some traveling and plan to visit China in April on an L tourist. This is more then 3 months away from the date we leave the UK so we cannot apply for out visa before we leave. We will be in Australia before we visit china, so is is possible for us, as UK citizens, to apply for our entry permit in Australia, and if so, where can we do it. Thanks in advance.
