One of the five most dangerous shark species has been found living in the Swan River prompting a warning from authorities.
Three bull sharks were captured in the Swan River this week and the Swan River Trust is urging people to remain vigilant when visiting the area specifically near Maylands.
The sharks, ranging in size from 70cm to 1.1m, were caught on Tuesday and Wednesday night between the South Perth foreshore and the Maylands Yacht Club.

"We don't know a lot about bull sharks in the Swan River as there hasn't been any targeted research done on them; however anecdotal evidence would indicate they stay in the deeper waters of the Swan," he said.
Shark sightings can be reported to Water Police on 9442 8600 at any time.

i have noticed a very large increase in bull shark numbers...especially big ones
in the 2m + range, schooling in the shallow areas around pelican point and along Melville beach parade as well...they look quite aggresive as well
i would advise people who dont windsurf to give these areas a wide berth.
I have seen them at Pt Walter too! Especially in the shallow area near the sand bar.

I saw one leap out of the water onto the fly bridge of a beautiful big motor boat and *sniff* take the captain in its jaws and then swim off. Please people, be careful out there.
i heard a guy saw a tiger shark as well in the river, must be some type of secret govermant experiment
i had one just next to the cut down here while i was spearfishing. a good 8 to 10 footer. it just cruised past me, rounded the rock wall and into the Cut. it was so close i could see its eye move. maybe 6 metres away. awesome bull shark.
The best thing to do if your caught in the water is to ink yourself and make yourself look as least attractive as possible! Remember to wash before leaving the water as it can be a bit embarressing
No sharks in the river it is all bull (shark)..... they are too scare of the deadly jelly fish plague and the ones that survived have all been nibbled away by the giants blow fish!!!! stay away ppl the Swan is no place for you to swim. (or kite) ![}:)] [}:)][}:)] [}:)]
Yip, count me in- I've seen em. I was standing on the sand bar at Lucky Bay adjusting my harness lines when 2 cruised past. I reckon they were around 4 to 6 foot (and fat too, they looked like a Staffie with fins). I ignored the badly located harness lines and got back on the board remarkably quickly and if I remember correctly, I didn't fall off the rest of the session!
Big fin cruised past me yesterday 2m away when I was slogging in a lull in that muddy soup that covers the channel between Ward Pt and Pt Grey in an easterly. It weren't no dolphin fin.
Went back to Novara straight after that to derig and rinse my wetsuit.
Couple of years ago my mate and I were fishing in a 10 ft alli dingy (small crappy excuse for a boat with a 2HP engine) saw fin and my mate said look.... dolphin then it came closer and it was no dolphin, 2m hammer head.... still remember his eyes
was staring at us.... bet he was thinking errrrrrr interresting lunch in that alli tin! scared the Jesus out of us..... got rid of the tinny same week!
That was between Garden and the shore, south side of the causeway, was looking safe.... no waves and sheltered! Yeah right
