From a Telstra TID connection I’m getting around 400ms (Sydney, LA, New York, UK, France, Israel).  I’m curious if there’s a less-latent path on another provider/route (RDP sessions are painfully slow).

300ms is well above the 100ms limit needed for a system to feel interactive.

Only choice you've got is to move the end points closer together.
