The closest I could find to this moth seems to be Dichromodes estigmaria, although that species doesn't seem to have been observed in South Australia (at least on iNat, ALA and lepidoptera.butterflyhouse). This specimen also lacks the two black markings along the costa of each forewing so I am not certain of the ID. Any help much appreciated!

Images sourced from previous submission but now the Subject=the toadie not the whiting.

[And I note that a second Smooth Toadfish is incidentally visible in bottom L corner in at least one image version,but appears un-involved in the possible cleaning episode involving the mid-frame Smooth Toadfish]

Personal Opinion only:- the puffer and the whiting are both clients or prospective clients of one or more Rockpool Shrimp ,which are using the low rock as a station.

The general appearance suggests some sort of crab, but that's not quite right (I don't think).
Image #1 & #2 are top and bottom views respectively. Image #3 is an attempt to show its tail ... otherwise wrapped tighly against the body.
Image #4 highlights interesting hooks on what I think are its rear legs.

growing as taller shrubs over a dwarf shrubland of Limonium sp and Sarcocornia. No mature dried spikes, lots of shed spikes with pagoda-like bracts, lots of flowers and young fruit spikes with identifiable seed.
The plant in these photos has been vouchered into the Adelaide Herbarium, and I will update this note once the voucher details are uploaded into the Atlas of Living Australia

Old fruit and new fruit and flowers present. 0.3km from Ferry Terminal gate on Lucky Bay Road. Seasonally wet samphire swamp with T pruinosa, Disphyma.

SUBSPECIES aff longispicata.
Near boat ramp, Port Augusta. Fruit only contain immature seed as yet, last seasons seed have all shed, leaving empty bracts.

Note re the use of "aff" longispicata: the plant commonly described as T halocnemoides longispicata in SA differs in significant ways from the type described by Wilson (Nuytsia 3:1). The type is around 30cm high and occurs inland. The SA plants that use this name occur in the intertidal zone in metasaline situations and may be shrubs to 1.4m tall, although usually shorter.

Small "ruby" form of T halocnemoides. Growing on a higher level embayment of Seagull Lake. Associated vegetation include Sarcocornia quinqueflora, Wilsonia humilis, T arbuscula, the common shrubby form of T halocnemoides, slightly upslope of T flabelliformis

Old and new fruit present. Growing on red clay is sand not far from Pink Lake at Port Augusta, just west of railway, in a saltbush vegetation association

Smaller adult with interesting moluscan kin close by -a Neodoris species nudibranch.( I'm unsure whether the impression of inter-species curiosity is real or imagined but I took multiple photos and I've always thought these pics are good PR for molluscs generally!)

lots in this one spot of loose dirt in a mostly dry but flood area. Could be from when ever the last flood was, but I don't know how long the waters would sit once the torrent was done. Could have washed here from the last flood when ever that was. In that case, did they wash from ancient deposits or from the bottom of the pond upstream?

First image is less sharp than 2nd image.Use 2nd image to locate the very small Upside-down Pipefish which is very near the head of the much larger Rock Ling ( on viewer's LHS of ling's head).
Look for the pipefish's distinctive caudal fin which has thin white linear markings and olive greenish centre and(rather fancifully!) resembles a very small fan worm. Or is somewhat parasol-like.
Now scroll sideways to see the much more cryptic body and head of the pipefish.
The tail-fin is this temperate cleaner pipefish's guild sign.
