Premier League clubs Tottenham Hotspur, Newcastle United and West Ham United have all been linked with moves for the highly-rated centre-forward, who scored 18 goals in his debut top campaign last term.
Following QPR's relegation to the Championship, Austin has been expected to leave Loftus Road, with the aforementioned clubs vying for his signature.
This has led Rangers boss Ramsey to admit his star frontman is likely to leave - but only for the right price.
"He would be a big loss for any club in any division,” the coach said, according to talkSPORT.
“He's going to be a massive gain for anybody that has the money to buy him. If the owners get the right money, I think he will be moving on.
"The QPR fans have showed him absolutely fantastic support, and I think QPR as a club have helped him to be on the stage that he is now. “
Austin disappointed somewhat as QPR fell to a defeat at the hands of Championship outfit Charlton on the opening day of the new campaign.
The 26-year-old had the share of his side's best chances throughout the tie, but he found himself removed from the action late on after an ineffective display.
Ultimately, goals from Charlton's Tony Watt and Morgan Fox ensured a winning start to the season for their London rivals as Chris Ramsey's side were soundly beaten.
