Okay! Well since my experience with live specimens is limited to Hydrophilus sp., I will leave this one to you. I just thought it would be good to put the info out there since they are similar in appearance.
I have to disagree with you on palpi length. I've seen collected Dystids with long palpi like this though, yes, they are typically shorter. However, I usually deal with collected (and very dead) specimens when it comes to beetles so I am unsure of the behavioral aspect of not folding the antennae.
Not necessarily. It could also by a Dysticid. To tell the difference, you need to look at the ventral side (the bottom). If it has a spine that runs from the head, nearly to the end and has clubbed antennae, it is a Hydrophilid. If it has no spine AND filamentous antennae it is a Dysticid.
Jemma is correct. The subspecies is the Pacific gopher snake (P. c. catenifer) or an intergrade if you are a subspecies person.
Hey Mark, I was looking around, and I'm certain that this is in the subfamily Goniinae. Here's a website cataloging a lot of tachinids of Brisbane area of Australia. You might find some overlap.

Another cockroach
This does not look like a German cockroach to me. German roaches have two lines on the thorax which I do not see in these pictures.
I can't see the postscutellum (which is always bulging in Tachinids and is a character of the family) but the wing veination looks correct for Tachinidae.
