I'm taking it easy on my last half day: sleep in, plan, then have a small breakfast at 11 am...
Afterwards, I'll go to Darwin Airport and drop off my car in the scorching heat.
Darwin Airport is cute - a relatively large domestic section that you can enter first. You don't even have to give up liquids at the security control... :-)
In the National Terminal, there is an access to the International Terminal - this terminal has exactly 4 departure gates and a lounge... ;-)
Finally, at 3:45 pm local time in Darwin, my first leg of the trip to Singapore begins.
