How to use this ranking
The order is a map-planning ranking, not a claim about today's fish population. It favors larger mapped waters and gives survey-backed contours a three-times data-quality boost. Agency population surveys, current regulations, access and recent conditions should make the final decision.

When to fish giant trevally in Western Australia
- Spring 4–30 ft — Australian spring: search the mapped shallow habitat and current edges; summer is a broad regional tendency, not a catch forecast.
- Summer 4–30 ft — Australian summer: work warm, moving water around structure and confirm bait, tide and wet-season access locally.
- Fall 4–56 ft — Australian autumn: use current, temperature and visible forage to choose between shallow habitat and the first major drop.
- Winter 18–80 ft — Australian winter: slow down on deeper structure and do not infer presence from a regional roster without local signs.
