As I settle into my economy seat it occurs to me that the Big Bottle will be a lot smaller than the fuselage of this aircraft, which brings on a mild wave of claustrophobia…

The Bottle will be see-through, sure but my mind turns to escape routes as I crank up Boards of Canada on my headset and try to ignore the flight attendant’s announcement that the forward door was now closed.

Me and my illustrious researcher Julie, with her sense of direction (phew) and impeccable organisational skills (double phew) are on our first recce.  As soon as I learn how to start the car.

When Trent from Queensland Dept of Transport starts talking about shipping lanes, police presence and sticking close to the starboard bank (pardon my French) I’m thinking wow, shit is starting to get real…

We delve the delights of Brisbane boat ramps and take a ferry up river (or is that down river?) to Southbank.

Sitting out the back we watch a charming 4-year boy befriend two German tourists and together they try to spot bull sharks off the stern.  As we pass office blocks, I see eyeballs…and I wonder if, the day I start swimming from Brisvegas, 7 years later I’ll get to talk to Wilko on the Today show again…
