Now, however, I see that the bull sharks, which are known to swim all the way up to Ipswich, are also in the news:
A young rower had her scull attacked at the weekend while training near the Kurilpa Bridge in the CBD.Yikes. There's a photo at the link if you want to see the damage to the boat.
Coach Peter Toon said teeth marks were left on the rower's craft after the attack.
"She saw the fin and it went around and gave it a big snap on the stern of the boat," he said.
"It put some big gouges into it and it upset her quite a bit as you could imagine."
Mr Toon said despite the scary incident, the rower had been back on the water this week.
"I've been coaching for over 25 years and I've never heard of an incident where a bull shark has attacked a rower."
I wrote a lengthy post about bull sharks in the river in 2010.
