Thanks for all the replies! I've since spoken with Dell USA regarding this.
Stores that I am aware of that carry Dell products include Best Buy, Fry's Electronics, Office Max, Office Depot, and Staples. Probably your family member can work through whichever of those is close to where she will be staying.
Unfortunately this version is not offered through bricks and mortar stores.
Uhmm, you can't buy it online and they send it to Australia?
No, Dell USA will not ship to Australia. In fact, if I purchase online for delivery in USA using an Australian card, I will need to call the Dell credit team to verify the order before they will even process it.
I think there are restrictions, like here, Turkiye. In Turkiye, one can not buy and import to the country online anything which price is much than 150$ according to customs regulations. But one can bring along from other countries. So, many of my friends call their relatives who live outside to buy their needs and bring along to the country when coming for vacation.
For Australia there are tax/duty implications when the item is over $1,000 excluding freight.
So, it appears I need to order it and get it delivered to a residential/business address, as Dell will not send to motels/hotels. This makes it a bit tricky regarding timing, but I will still keep looking into it to try to make it come together.
