Hi Sean,
We recently looked into this and whether a physical location is required or not, the requirement is that you have to open a actual broker-dealer in Australia. This is a large undertaking that both Tasty and IB have chosen to do. You'll notice on their website that they have separate brokerages in Australia. This is not something that Tradier and/or our clearing firm Apex will be undertaking at this time.
Sincerely,
Chris Lepore
