12-13 mm long.
Several individuals seen burrowing into a decaying log.
Images are of 3 individuals (1 =images 1-15; 2 = 16-18; 3 = 19-29).
I think Cerceris - but I think it is not one of the regularly observed species. I will try to get some better photos.
Approx 1cm long . Caught and released
Possibly multiple different individuals. Very dark black all over (with what appeared to be slighty paler dark grey pronotum), difficult to bring out details in photos.
Unfortunately the only photo from a very short observation. Certainly not confident in this ID but don't have any other ideas.
Captured in garden. was digging holes in garden pots.
Approx 13mm long . Caught and released
Approx 1cm long .Caught and released
This wasp tried to deposit (perhaps successfully) egg/s into this case moth lava for at least 26 minutes that I observed - time from first photo to last. Nearly all the probing (at least a couple of hundred attempts) was around the entrance area with no obvious success.
Same wasp species as observation 193565084 taken in same place on a different day.
Female.
Bodylength about 8-9 mm.
Spotted deceased in a spider web
Found on a plant in the garden Rainforest Patch.
Rescued from a dog's bowl of water, so was busy drying itself off.
Adult Male, ~18mm long.
Note antennae shape & spurs, keel, 11 flagellomeres.
Different front leg shape to female, as well as posterior of course.
Lack of yellow tip isn't gender based; nor diagnostic.
Note the bent hairs on the leading edge of the forewing. This occurs in both genders.

Notice the extra abdominal segment compared with our female Cerceris sp.
7 segments for males & 6 for females.
NB: The petiole is counted as part of the abdomen.
ES02 ~12mm long.

Marie found it digging the ground.
Female as it has 6, not 7, abdominal segments (includes the petiole/waist)
at flowers of Melaleuca lanceolata
On the bank of Ross River. Small, on grass seed head.
Large wasp, at least 3cm long, sitting on acacia leaves during a shower of rain. Half a dozen of them at this location but only photographed this one.

In the mixed native, non-native garden with veggie patch on a rural block adjacent to Blakely's Red Gum and Red Box woodland. On mint flower.
I think this is a Cerceris sp. probably Cerceris australis. See also an earlier post of a wasp of similar appearance.
In the earlier post, I added the following comment:
Ken Walker advises that "Cerceris was revised in 1981 by Howard Evans and he recognised 47 species - the two most common were C. antipodes and C. australis."
Ken suspected this might prove to be C. australis.
Based on photos on ALA and elsewhere, I also think that this is probably C. australis.
The photos of this and the one in earlier observation were all taken on the same day and location on the same plant, a silk pod vine.
found in montane swamp (Packers Swamp) at elevation 850 Metres
Seen with prey of blowfly or drone fly in first photo.
