Dexiini is a tribe of flies in the family Tachinidae, known as bristle flies. I believe this one is genus Prosena.
They are mostly parasitic in larval Coleoptera, especially Scarabaeidae.
10 mm body length.

Many of these tiny fly species within family Sepsidae resemble ants.
And many Sepsids have a curious wing-waving habit made more apparent by the tiny dark patches at the wing end.
They can often be found around dung or decaying plant and animal material where eggs are laid and larvae develop.
Also commonly known as scavenger flies and ensign flies.
This is Parapalaeosepsis plebeia. I singled this one out, but at the time of taking the image, there were hundreds all over the kangaroo paw flowers.
Around 4 mm length.

Native to the south-east of this country. It has been observed that typically, this species will visit a carcass early in the decomposition process.
I also learned that the females of this species are ovoviviparous, laying around fifty larvae (maggots) sheathed in a chorion (egg shell) which hatch almost instantaneously.
And with fascination I read that this is the most forensically important fly in New South Wales, where, for example, it was utilised in over 30% of cases between 1984 and 2001.
Body length 10 mm.

Friday's fly is one within genus Calliphora, commonly known as blow or bottle flies. I learned that we have the highest diversity within this genus, here in Australia.
I think this might be Calliphora stygia, but will do more research to confirm.
Adults of Calliphora have a grey or black thorax.
Around 10 mm body length.

Friday's fly: native to this country - there were many of these shiny little flies on the native Leptospermum polygalifolium.
This ID is based on the fact this is the only described species with frons broadly orange anteriorly and mid/hind legs with tarsi darkened on more than just the apical segment.
Tiny, no more than 5 mm in length.

It's the end of the week once again here in Australia...and here's a beauty for Fly Day Friday.
A large bristle fly with gorgeous colouration. A fly of parasitic nature, living as parasites on other insects or their larvae. The females lay the eggs directly on the host's body. As fully-formed insects, parasite flies feed on various sweet liquids, such as nectar.
I believe Microtropesa sinuata.
Female, 20 mm length

Apart from the fact that they both have muscoid antennae, I have no idea which family, let along genus, these two species are. There's antennae like that in many families of fly.
Flies are a sod to sneak up on with a phone camera, even when they're distracted.
EDIT: Thanks to servitude for the ID :)
There were at least three of these huge bee-flies pollinating the Conostylis. I took the photos in October 2012, on my old phone, but I still haven't found an ID. Look at them! They're huge!

EDIT: Jean Hort suggested Oncodosia - apparently there's four species, all found only in Southern Australia, and judging by the black and white checks, this one is O. patula, which is found here in Perth.
