Speaking at the club's Annual General Meeting - co-chairman Mike Garlick and chief executive Lee Hoos insist that letting Austin leave is not part of their plans.
Garlick insisted: "We have no plans to sell Charlie at the minute. We see him as an integral part of our squad for this season.
"If you remember last season he was injured quite a bit and the season we bought him he was injured as well, but we want him playing for us this season and you are going to see that happen."
Hoos added: "We had the same situation last year with Jay Rodriguez and we said 'no, we will not sell him in January'.
"We have no plans to sell Charlie either! We do not want to sell Charlie and we would not encourage offers on Charlie.
"We just want to keep Charlie and let him enjoy his football as he is doing right now and keep scoring goals and let's see where it takes us at the end of the season."
