hi mate, salmon, tailor and kings are always on the move and rarely feed on the bottom so baits and sinkers arent the best approach.
id be hitting the same spots youve been getting fish with small metal lures.
if you see birds and bustups start winding as soon as it hits the water, if not then let it sink to different depths before retreving.
keep moving until you find them.
pelagics and landbased is not easy.
