A couple have come up here on FR over the years.
Paddle Crabs have a slightly different pattern on their shell as well as a slightly different shell shape.

My only thoughts @Little_Flatty of using the Wonder Wobbler in the Parra would be it getting snagged up on Rocks/Debris/Mangrove Roots etc.
I used mine for Flathead on a sandy beach.
My first lure caught Flathead was on a Wonder Wobbler when I was quite young and that was just a Hop Hop Hop type retrieve, as for a Tassie Devil I've never used one.
Great read LF. I fish when I can and sometimes have a ride with the Lads on Tuesday night at SOP.
Youth was a while ago for me and some memories fade ......
A day out is a day out, better than at home in front of the Telly hey.
Good luck down the Snowys and if you going next week it could get a tad cold.
Looking forward to a report of BIG Trout 🤞
I would also agree with @Bluebenbomb Sydney Cardinalfish.
5 Dark stripes along the body and a bigger gap between the 2nd and 3rd one.
If you have a photo of the tail would help as they have a spot on the tail base.
The "Common" name is a Ling, well that's what I've always called them or as @dirvin21 said, Rock Ling (plus a few others)
... but the "Official Common name" 🤷♂️ is Largetooth Beardie.
