The 26-year-old scored 18 goals in the Premier League last season, but could not help prevent QPR being relegated from the top flight.
Austin, who received his first England call-up in May, started QPR's 2-0 Championship loss at Charlton on Saturday despite being linked with a move away from the club.
"If the owners get the right money, I think he will be moving on," Ramsey said after the defeat at The Valley.
"He would be a big loss for any club in any division. He's going to be a massive gain for anybody that has the money to buy him."
Having begun his career at non-league Poole Town, Austin signed for Swindon Town in 2009 and fired 37 goals before moving to Burnley where we went on to strike 45 goals.
'I'm available until I'm told otherwise'
Charlie Austin on the transfer speculation
QPR paid £4m for the forward in 2013 and his 20 goals in his first season helped the west London side win promotion from the Championship.
He continued to find the net in the Premier League last season, and despite The Rs relegation, he won a call-up for the Three Lions at the end of the season.
"I'm available until I'm told otherwise," Austin told BBC Sport when asked if he was leaving QPR.
"It's out of my hands, it's up to what the club wants to do."
