I'm based in Hobart, Tasmania and there's no reason why I can't deliver your canoe or kayak or lampshade direct to your door if you live in Tasmania.
I've successfully sent a crate containing two Geodesic Airolites to Ireland so I'm practised in export procedures.
Air freight is an easy and relatively inexpensive way to ship within Australia. there are "special" rates for "long, thin" things. For example, a Snowshoe14 from Hobart to Cairns is approx $360 or a 17ft Baidarka from Hobart to Melbourne for about $160. Only a couple of things to remember -
(A) there is no insurance obtainable, so
(B) packaging is an additional cost, and
(C) you have to collect it from the receiving Airport as they do not offer a delivery service. I really should get around to checking Overseas Air freight rates.
