I have done some research for you and was surprised by the ‘hidden extras’ associated with the importation.
These were,
Port charges by Sydney agent $473.06
Quarantine inspection charge (AQIS) $172.00
Provide space for bike reassembly and destroy crate (AQIS supervised) $221.00
No import duty is payable on bikes, but GST is applicable on the current value of the machine. It needs to be valued and an independent valuer charges $150 for a call-out and written valuation. GST was also levied on the freight charge.

Hope this helps and hope we get to ride together soon!!
