"The realism of professional coaching is that you have to give any offer serious consideration," Jones told the Courier Mail.
"What I am, is willing to listen if they want to speak to me, just as a person in any job would listen to an offer."
Jones, who was sacked from his job in charge of Wallabies this time last year, has already knocked back two national coaching jobs this year, outlining his commitment to the Reds.
He added: "The Australian Rugby Union was committed to me three months before I was sacked, so, like any job, you have to keep an open mind.
"The English have the most resources and the potential to be rugby's most powerful nation. That's why any coach would think about a position there."
World champions England have struggled recently, having only won nine Tests from the past 22, forcing Andy Robinson's departure.
While England have been below par, New Zealand have been in devastating form having lost only one Test in their past 20 matches, something Jones was quick to point out.
"It's going to be hard for any England coach to win next year's World Cup," he said.
"Every nation is playing for second right now with the way the All Blacks are going."
