Best tide state to fish Port River (Garden Island)

Being a sheltered upper-estuary spot wrapped in mangroves, Garden Island fishes in conditions that would blow out the open metro jetties — there is no swell to wash you off anything, and the land knocks the worst out of the prevailing afternoon sea breeze. The tide is the variable that matters: the incoming, and the hour either side of high, is when bait and fish push up onto the edges and the bite switches on; the bottom of a big run-out can leave the flats bare and the fish sulking in the channel. After heavy rain the upper river colours up and dirties, which can slow the lure bream but does not stop the bait fishing. Hot, still summer days fish best early and late and around the tide rather than through the glare of midday.

What anglers target here

Anglers fishing Port River (Garden Island) typically time sessions around the tide for black bream, mulloway (jewfish), yelloweye mullet, australian salmon, and flathead.
