Is Mosman Bay Jetty actually deep?

Yes — Mosman Bay is one of the deepest pockets in the lower Swan, which is the main reason mulloway hold here. The drop-off at the end of the jetty is where the depth change works in your favour.

Can you fish Mosman Bay Jetty at night?

Yes — the jetty has good lighting and is one of the more comfortable after-dark options on the Swan. Mulloway are the standout target on a rising tide into dark.

Why does Mosman Bay fish well when the coast is blown out?

The bay is east-facing and tucked into the south bank, so it's sheltered from the afternoon SW seabreeze. When Fremantle's blown out, Mosman is often glassy.

What's the rig for bream off the Mosman pylons?

A small running sinker rig on 4–6lb fluoro leader, baited with prawn, bloodworm or small mulie strip fished tight to the pylons. Light gear suits the clear water — heavy leaders get refused.
