Just done it,
For perth I think a Hardtail would be good, get a good set of lights as you will spend lots of the summer riding at night as it is so damm hot.
I sent 2 bikes and a bag of stuff, boxed the bikes and packed in loads of other stuff so was about 0.5m3 and 90kg by boat
Cost was about £250 to ship
Then to unload the container was about £75
After that it needed inspecting by AQUIS this cost £50
They found some small areas of dirt so it needed cleaned this cost £50
(I had cleaned it with every brush know to man and it was clean when it went into the box)
I have stopped adding it up.
Bikes appear to be pricey everywhere right now have a google for Perth Bike shops and see what they are doing as specials on 08’s and there are a couple of good dealers about. 1 Perth Bike Shop or try the speccy dealer locator loads over there Locator
Mail me if you need some more info
BTW I havn’t worked out sending them back but I’m doing that soon….
From my experience see how much air freight would be.
For more fun the boat is unloaded in fremantle and all the offices are at the airport 🙁
