The very pleasant crossword that we have come to expect from Gemelo. There are several misleading and intricate pieces of wordplay.
My guess is that anyone who does these crosswords will have a copy of Chambers to hand and so won’t need everything to be spelled out. In the parsing I have confined myself to explaining when the wordplay is not immediately clear.

| ACROSS | ||
| 1 | AUKS |
Australia contains a thousand seabirds (4)
|
| Au(k)s — a nice easy one to get us started | ||
| 4 | RED DWARF |
Sitcom star (8, 2 words)
|
| 2 defs: this sitcom and a type of star | ||
| 10 | SNAKEHEAD |
Chinese criminal‘s son almost exposed source (9)
|
| s nake[d] head | ||
| 11 | KAIAK |
Animal occasionally found in middle of trekking canoe (5)

| 17 | INSULA |
Briefly disparage a Roman house (6)
|
| insul[t] a | ||
| 19 | ETIOLIN |
String instrument originally covered in extremely erodent yellow pigment (7)
|
| violin, its original v covered by e[roden]t | ||
| 20 | ARUM |
Perennial American suspect (4)
|
| A rum — Chambers gives queer, droll, odd, strange for rum. Suspect I suppose. | ||
| 21 | AURA |
Feel money in Iceland running short (4)
|
| aura[r] — 1/100 of a krona | ||
| 23 | NET GAME |
Spooner’s become famous for some tennis (7, 2 words)
|
| “get name” — a net game hardly seems to me to be much of a thing, but Chambers thinks otherwise | ||
| 25 | STATED |
Set forth conclusion of report in full (6)
|
| s([repor]t)ated — full = sated as in agreeably fed up | ||
| 27 | ASTONISHMENT |
Wonder Woman, having dismissed lead, sent this cast (12)
|
| ([w]oman sent this)* | ||
| 29 | GAITS |
Ways to move Scottish children (5)
|
| 2 defs | ||
| 30 | MOTIF |
Irish girl provided that idea (5)
|
| mot if — Chambers doesn’t actually say that a motif is an idea: the sense which just about covers this is ‘a dominant or recurrent theme in a musical, artistic or literary work’ | ||
| 32 | MAY AS WELL |
Not just April? Why not? (9, 3 words)
|
| May follows April, so we have a nice little joke where the first part gives a cryptic indication and the underlined part the definition | ||
| 33 | NON-ELECT |
Unchosen knight once let out (8)
|
| N (once let)* — the word isn’t defined so far as I can see, but is in the huge list of ‘non-‘words, where the answer is pretty obvious | ||
| 34 | OPUS |
Vase that’s from ancient Egypt but can work (4)
|
| [can]opus — but = except for | ||
| DOWN | ||
| 1 | AS SURE AS A GUN |
Certainly soft waste to give one locally (12, 5 words)
|
| ass {a ‘soft’} urea {waste} sag {give} un {one locally} — I don’t usually give the matches of words in the clue to words in the answer, because it clutters and doesn’t in my opinion usually help, but the parsing here is so tortuous that it might do so. | ||
| 2 | UNKNOT |
Free country welcoming national poll (6)
|
| U(n)K not — in order to have a nice misleading surface, the second meaning of ‘not’ is used, although it actually says ‘polled’ not ‘poll’; not sure how they’re the same | ||
| 3 | SKI |
Runner hides missing poles (3)
|
| ski[NS] | ||
| 4 | REARM |

| 7 | A NATURA REI |
From the case’s quality bats, retain 21 (10, 3 words)
|
| ah, Latin — so it now makes sense. I thought I had made a mistake — surely it doesn’t end in I — *(retain aura) | ||
| 8 | RARE |
Extraordinary feature of previous answer (4)
|
| Hidden in ‘a natuRA REi’, the previous answer | ||
| 9 | FUNDAMENTALS |

|
| (about)* but you replace the u by the other part of EU, which is e | ||
| 16 | BINDI-EYE |
Red mark round aperture in Australian plant (8)
|
| bindi eye — a bindi is a red mark (the facial decoration traditionally worn by Indian women) and an eye is a round aperture — clever use of round not as one of its three wordplay indicators | ||

What covered Roman soldier‘s face when climbing (5)

| 22 | MENSAL |
Periodic table-related (6)

| 26 | GHOST |
Shadow Home Secretary going around centre for injured (5)
