My item got to me very quick and i am happy with global shipping price i paid only 24 $ for 13 kg package. Took a week to get to me.

Heavy items can be very cheap shipping, it's the lightweight stuff you should avoid. You could see a similat charge on a 100 gram package.

Re. the tracking.

Memphis is a FedEx cargo hub airport, the package is probably on a FedEx plane heading for Australia by now. The main delay center seems to be Erlanger, once out of there progress should be steady.
