Swivel can you send me some more info about the access issue?
Jansons or Coxens?
That's right in the ACS wheelhouse, I'll get the board onto it next week.

Jansons

Up until 10 - 12 years ago, you could drive through. The bridge was pretty shitty and the track wasn't that great, particularly in the wet. Heard a couple of stories about people doing the wrong thing like not closing gates and chopping up the pasture. Understandable the farmer got sick of it

New bridge went in about 6 or 7 years ago (my memory ain't anything like yours). Parks Vic were our client for the river phys chem profiles. As soon as construction started on the new bridge I asked about access and they were seemingly certain it would be reopened to the public. Why else would a bridge be publicly funded? The farmer locked the gates immediately upon bridge completion. Last time I was there was about 18 months ago and the gate was still locked

Old report, but sheeeit!
On the day two surfers were attacked by sharks around Gracetown, a shark watch helicopter crew member says he saw fifteen large sharks between North Point and Kilcarnup.
It never felt better to be waiting for a plane to get out of the WA sharkpit

Not much more than a year of data to draw solid conclusions, but here’s a monthly summary of GWS tags from the DPI drumlines from Lennox to Forster, Dec 2016 to March 2018.

What do you make of it? Water temps, whale migration? Fish schooling (or absence)? Sure only one year but looks like a pattern

Hopefully the DPI are putting all that data together.
And will publish findings, given its taxpayer funded.
I merely input a few numbers into excel two hours per month, out of interest.

But yes lower water temps and whale season might be the biggies.

Now that are old friends are back I wonder if crowds will cool down. `can't be long until someone gets bumped or worse.

Nice little flurry of activity to set off a flat spell.
Cue scientists telling us numbers of white sharks are declining and attacks are because more people using the water.
Wonder who gave birth to all these juv/sub-adults then`? Aliens?

Well a community survey by the DPI just let out to "stakeholders" reckons support for shark nets in the area has collapsed in the past year -- except among surfers.

What looks interesting in their stats is the fact that in the first net trial they got nine "target" sharks and in the second they got two.

Do sharks alter behaviour as a result of the presence of nets? Do they alter behaviour as a result of drumline tag and release? Are people's view of shark nets affected by the number (or lack) of attacks? Do people change behaviour as a result of attacks and word-of-mouth on shark activity?

Plenty of sharks being tagged and released elsewhere too. A large white shark attacked and killed a seal within 50m of a group of surfers at Queenscliff in June. My training crew saw at least two large white sharks surface cruising during their Molokai training back around that time. You NEVER saw white sharks in that close in years past. Outside yeah but not within cooee of headlands.

What about support for the smart drumlines?

I reckon the whale population is in overshoot so that's why we are seeing the dying whales in decent numbers, and lots of shark food.
Wouldn't be surprised to find they're maturing earlier and having larger litters.
Some pretty small changes to those factors could lead to a massive increase in population growth rates.

Nick support for nets has collapsed amongst surfers here as well.

Support for smart drumlines has increased....even the most doctrinaire greenie seems to accept it now.

As for your other questions NC.......

1. Can't seem to find any data or even expert opinion on that.......but dolphins seem to get caught in the nets and they are much more intelligent than sharks.
I think the lack of target sharks is more of a seasonal factor. ie, there are less white sharks (and bull sharks) here in summer. More tigers but they seem to stay deep.

2. They seem to, at least in the short term. There have been sharks tagged and released then recaptured so any effect might be short lived or not statistically significant. Too early to tell.

3. No. They are affected primarily by the reporting of the by catch.

4. Yes. An attack or cluster of attacks or even bumpings, circling or other encounters will see certain spots around Ballina and most open beaches become deserted. Crowds will cluster.

Nowhere near the scale as in N.NSW though.

Go look at the last 2 weeks worth of activity on shark smart.

Just about all the bouys from Hawkes Nest to Byron are getting pinged a lot more often last month or so.
It’s a head scratcher that if they wanted to gain more tag data, they’re have drumlines back in at Forster, Port and Coffs etc. but they don’t.
