Personally, I'm a bit perplexed at all the increased attention on Domestic terminal security. Even this recent incident was allegedly targeting an international flight, so unless there's some other intelligence which they are not disclosing regarding an increased threat or intention to target Domestic flights, I don't understand the need to introduce International-style security restrictions to our Domestic terminals, such as preventing non-travelling public to enter secure areas and introducing International-style LAGS restrictions.
I'm undecided whether to be cynical about the recent scare or to consider it as some very clever use of media. Disrupt the flow of domestic passengers and the message will be shouted from the roof tops. Any others out there with a mincer full of PE might get the hint that they shouldn't bother.
The big question out of all this is the transfer of the materials into Australia. There's some implications there that I'm not delving into on a public forum.
