GME Is still available to buy on ig.com for aussies.

. .

I signed up yesterday and set it to auto purchase on market open. Dont use bank transfer for funds as that will prob take 3 days to clear (if you want GME by today/tomorrow)

Also there is an extra form to fill out to trade on US markets. Whole thing took me 20 minutes.

Just checked and its definitely still available. Screenshot here for proof.

EDIT: "Stake" app also had GME available to buy. But I couldnt get the express deposit option (1 day to clear) working. So I wasnt going to risk it.

EDIT 2: Here is a list of other Australian trading sites available. Not all of them have US stocks, and some of them charge commissions etc (ig.com is 0% commissions). One of these will work, but you are running out of time for money to clear in time for friday(US time).

Actually calling these companies on the phone might be the quickest option if you have no luck with the website/app.
