Kirkham have a nice price sheet you can build your car with. I ticked the boxes for a basic 427, brushed with stripes and fitted with a 5 speed tremec and aluminium 427. Came to about $100K USD.
Using the Australian Customs guidelines for importing cars

I figured this car would cost about $165K AUD to land here based on the $AUD being worth about US90cents. This includes GST, Customs Duty of 10% and LCT, plus about $6K to ship.
I'm not planning to buy one, but are there any massive holes in this calculation?
