I submitted a talk on Propellor and a followup tutorial for LCA. On the off chance they can fly me down there I want to provide maximum value. The one time I attended, in 2013 was really great experience. The travel time to SYD from here is nearly a full 24 hours, so I wouldn't want to do it every year though.
BTW, my sister told me there's a train from SYD up to an overnight ferry to Hobart. Seems like a great way to make the last leg of the trip.
