The pair have been linked with R's departures throughout the summer and the west London club's latest move is suggested to be a poignant one towards that end.
West Ham's move for Green makes sense considering the shaky start made by Adrian's back-up Darren Randolph, although Palace boss Alan Pardew has recently been reported to have ruled a move out for Austin. That said, other clubs are still reportedly interested.
How will QPR manage without the duo?
Should West Ham snap Green up and Austin leave Loftus Road - for Crystal Palace or anyone else - the blow to QPR's hopes in the Championship will be notable.
In goal, though, the R's have strengthened by signing Alex Smithies. But it's the loss of Austin that will no doubt hurt the west London side the most.
The 26-year-old is already the Championship's top scorer this season - but QPR have in the past stated that the striker is free to go if he wants to and if his valuation is met. Chris Ramsey and co will no doubt have prepared for a departure.
