There are services like shipito and so forth and some service supposedly run by auspost themselves (shopmate).
Problem is each one I've looked into has shit reviews, stories of overcharging and weird parcel handling put me off, thankfully being a tf collector if its not robotkingdom giving me a more expensive workaround its
amazon.au and its "global store" which helps out (sometimes us locked stuff shows up ready for purchase, not everything though sadly).

If you got a US friend I'd suggest asking them for help, otherwise may my bump help
And for those baffled by OP's request Australian buyers are region locked from buying from any amazon except for the australian version due to amazon not wanting to fuck around with our government's demand for sellers to charge 10% gst ON THEIR BEHALF (ie no customs charges, we buy from say hlj which is japanese, but then to be compliant they have to charge us the gst FOR the government which they send off later, supposedly makes the process easy for australians but really it just the government knowing they could not enforce such a thing using auspost themselves)
