Blackfish

I recon the first is a Juvenile GT Caranx ignobilis
And the second is a Big Eye Trevally Caranax sexfasciatus
As you thought.
Great fun on the light gear.

A quick look and I recon Its a Eastern Frogfish. Batrachomoeus dubios.
Little phone makes it hard for me to see.
Try searching in Aquarium for one and that may help.
Update...
Quick look now. I recon Eastern frogfish

I'm with you Steve,
First is a Juvenile Six Spine and second is a Yellowfin.
Both Sixspine and Yellowfin have spines near the tail, Sixspine are more pronounced.

I would have to agree, Giant Trevally Caranx ignobilis.

Only on my phone at the momement but looks like a juvenile Queensland grouper .( Epinephelus lanceolatus)
I'll have a better look later

There's a few different Longtoms. I'll call this one a Stout Longtom. Tyosurus gavialoides.
There's also another common one, Barred Longtom Ablennes hains and seem Oceanic. I've only seen them out to sea especially on the north coast. To me they hang around in the same water as Wahoo/Mackeral etc, though I've seen them at 2&3 Mile out from the Entrance.
These I Alligator Gar but thats also a common name for Stout Longtom....... Bloody common names.
Thought I'd clear it up.
Thanks all.
.

I would also call it a Lesser Queenfish Scomberoides lysan.
My reasoning would be the head shape and the Dorsal fin colour. Hand is in the way a tad and the fish is tilted at a bit of a angle but all good.

Down coast.
Reception bad.
I recon Juz has it. I believe this came up on here before.
Try this section for what Juz has suggested. Bigeye.

I'll take a guess.
Smallspine Turretfish Tetrosomus reipublicae

Hard to say, have you a bigger picture but try Painted Grinner.

I've always called it a Estuary Catfish, but I've just noted it's sometimes called a Estuary Cobbler Cnidoglanis macrocephalus.

I recon ... though I could be mistaken.
I recon its a Yellowtail Barracuda Sphyraena obusata . I call it a Sea Pike, plus they have a few other common names. Note the Smaller Dorsal and Anal fins and are rounder (cylindrical) than the Longfin Pike. The stripe is also just above the Pectorial fin where the L/F Pike is higher.
Certainly not as common as Longfin Pike, but have caught them in Sydney Harbour and Botany Bay also up the Barrier reef.

Male, Crimson Banded Wrasse. Notolabrus gymnogenis.

First one I recon is a Female Crimson Banded Wrasse. Notolabrus gymnogenis

Teflon, you'll find Coral Hind/Cod have a Convex tail where a Coral trout will have a Concave tail.
That critter above has a Concave tail, so Trout.
Bit like Jewfish and Teraglin.

I would recon it's a Black Spot/ Malabar Cod Epinephelus malabaricus.
Unusual, mmmmm.

Juvenile Australian/Eastern Salmon. Arripis Trutta

I would guess both are Gunther's Wrasse.

Gunthers Wrasse. Pseudolabrus guentheri.
I think they've come up on here before, have a look on the search feature.

Eastern Kelpfish Chironemus marmoratus.
Very common little critter, pretty sure its come up on here before a few times.

Well Well Well. I recon thats a Maori Rockcod Epinephelus undulatostriatus.
Certainly unusual but I know of a good one taken at the Banks a couple of years ago and another good one up at Long Reef, but still unusual.
Good work.
Well thats what I recon.

In the search Bar at the top type in Painted Grinner, a few have come up on here over the years.
"Trachinocephalua myops"

Diamondfish also heard them called Mono's (Monodactylus argenteus) pretty common in Sydney but the Batfish, never seen one in Sydney before but anythings possible.
Certainly rare I would guess.

I would guess Longfin Perch. "Caprodon longimanus"
Maybe a male.

My guess ...
1) White-Eared Palma/Scalyfin Parma microlepis
2) Crested Weedfish. Cristiceps australis
