Bardi grub, crayfish, shrimp, yabbies, scrubworms, freshwater mussels. Fly fishing large imitation flies. Use a 1m 20kg monotrace for trolling. Braid or fusion lines. Trolling gear set for deep diving.
Cast bait close to cover of snags, under trees and root systems.
Quiet or gentle water flow areas are more successful waters to fish. Use one or two live shrimp hooked through the tail. When trolling repeated journeys over suspected logs and holes is required to entice the fish to strike. Use line up to 35kg for snaggy rivers to avoid tackle loss. Targeting backwaters and billabongs off the main river system can be productive because of fish entrapment due to water receded after flooding.
