I flew Sydney-LAX last month and no extra security at the SYD gate. In past years doing the same flight there has been extra security, liquid checks, and random pat downs at the gate, and only for US bound flights. It seems as though the other countries/airlines/airports are either ignoring the TSA requests or there has been a change in policy, given the amount of people who have been saying the same thing.
