The Australian pricing is in for these and they aren’t cheap:

I was hoping that they might be about the price of the SW Autotracking dobs, but they are several hundred dollars more.
If you do the math to work out the implicit shipping cost to Australia that is included in the price of these scopes (based on the prices on the Sirius website), the shipping for the XTg series is very high compared to the XTi and XXi series scopes they have for sale.
