Hey Geordie. Good to hear there is someone else with a TI in these waters. Crocs 150km offshore? That's a long ways though I have heard stories from charter operators spotting crocs a long ways out to sea. When do you plan to do a trip up to broome? I finish up my work in adelaide this year so will probably head off after new years some time. Might just leave the camper at home, drop the TI in at wirrina boat ramp and sail/peddle to broome. Would save a lot on fuel costs and I could hang a couple lures out the back and troll the whole way.
I do a bit of work up there (but mostly stuck in the office down in Perth) so not sure when I will get up there with the yak.
Wirrena marina sounds familliar, I did some diving out of there years ago to do an environmental assessment survey the planned sites to sink the dive wreck. That will be a long trip round to Broome, would make a great adventure docco, "The Really Long Way Round". Drop off in Perth for supplies on the way.
