Morwong in Australia — The Complete Fishing Guide

How to find + catch morwong in Australian waters. SST 12–20°C. Typical depth 30–200 m. Lures, baits, seasonality, and BiteCast layer mapping.

Morwong is a sought-after Australian reef + bottom species. Reef + sand boundaries on shelf. Bottom bait. This guide covers the depth + structure they live in, the techniques that work, and how to use BiteCast's subsurface temperature layer to locate productive water.

At a glance

  • Scientific name: Nemadactylus macropterus
  • Also known as: Jackass morwong
  • Segment: Reef + demersal
  • AU regions: NSW, VIC, TAS
  • Preferred SST: 1220 °C
  • Typical depth: 30200 m
  • Top baits: Squid, Pilchard, Fish strip

Where they live

Morwong live on reef + bottom structure. AU distribution: New South Wales, Victoria, Tasmania. Typical depth 30–200 m. They hold tight to specific structure: pinnacles, drop-offs, wrecks, isolated reef patches. Position the boat upcurrent + drop bait or jigs into the strike zone.

Conditions to find them

Use BiteCast's layer stack — surface SST is less useful than subsurface temp for bottom species, but knowing the broader thermal structure still matters:

SST

Filter for 1220 °C surface water on the BiteCast map. Sharp temperature fronts (1–2 °C breaks over 5–10 km) within that range are where bait pins up — your best-confidence zones. See SST layer explainer.

Subsurface temperature

Surface temp doesn't tell you what morwong is sitting in. Use the BiteCast subsurface-temp slider at your fishing depth (30–200 m) to confirm thermal structure. See subsurface-temp layer explainer.

Best techniques + tackle

Baits

Top baits in AU: Squid, Pilchard, Fish strip. Whole-fish baits + fresh squid are reef-fish staples. Match hook size to mouth size.

Local knowledge

Reef + sand boundaries on shelf. Bottom bait.

Seasonality by AU region

Morwong hold on structure year-round. Seasonal pulses depend on spawning behaviour + currents.

  • New South Wales: Year-round with regional pulses; check local sources.
  • Victoria: Year-round with regional pulses; check local sources.
  • Tasmania: Year-round with regional pulses; check local sources.

Common mistakes

  • Anchoring instead of drifting. Drift presentations cover more structure and find active fish faster.
  • Wrong jighead weight. Get to the bottom — undersized weights drift past structure without contacting it.
  • Ignoring tide direction. Fish position upcurrent of structure; drop your bait into the same lane as the fish are facing.

Compliance + regulations

Recreational size + bag limits vary by state and change regularly. Always verify current rules before keeping a fish. The morwong is regulated under each state's recreational fishing rules:

  • New South Wales: verify on NSW DPI Recreational Saltwater (or Freshwater) Fishing Rules
  • Victoria: verify on VFA (Victorian Fisheries Authority) recreational rules
  • Tasmania: verify on Tasmanian Inland Fisheries Service / DPIPWE rules

Marine park zoning may also apply — verify against current state rules. The above is descriptive reference, not legal advice.

Frequently asked

What's the best SST band for morwong in Australia?

12–20 °C. The temperature itself isn't the find — sharp fronts within that range concentrate bait, and that's where to fish.

When is the best time of year to fish for morwong?

Morwong hold on structure year-round. Seasonal pulses depend on spawning behaviour + currents.

What depth do morwong hold at?

Typical fishing depth 30–200 m. Use the BiteCast subsurface-temp layer at your fishing depth to confirm thermal structure.

What baits work for morwong?

Top AU baits: Squid, Pilchard, Fish strip. Whole-fish baits + fresh squid are reef-fish staples. Match hook size to mouth size.

Where in Australia is morwong commonly caught?

New South Wales, Victoria, Tasmania.
