Shields will fish any state of tide mate, just tends to be more the end or are between the end and the blocks at low water.... at high you can catch maccy most of the way along the pier on both sides... although not in as high numbers as towards the end. Don't be afraid of giving it a shot... plenty coalies to keep you entertained until you hook into maccy.... if no fish then have a chuck somewhere else.. keep moving till you find em!
