Just as an aside, there is a mammoth thread here
on CF about the Customs
& AQIS procedures and formalities that need to be observed when bring a yacht or boat into Australia
. Just skip towards the end to separate the fact from fiction.
Aussie_Sequoia is a member
here, and they have just completed bringing a Cat in on her own hull
. They have ever so kindly made a website (which basically condenses the abovementioned theread into fact only) that gives you uptodate date info. Website can be found here
Hope this helps.
