Dylan , the one on the left looks like a Lefty's deceiver , this is a classic bait fish pattern and pretty commonly used on Pelagic , as well as Barra . I am sure locally on the Goldy Trevas, flathead and Jewies will eat this.
The other one is hard to see but it looks like a type of woolly bugger, just a bit bigger than the fresh water version , with that big chunk of Marabou on the tail and the wound hackle over the body that fly should have heaps of movement and depending on the size I reckon it would be a great Bream fly.
Hope that helps
