O'Driscoll has gone on the record more than once saying that a potential swansong in Super Rugby is tempting, joking that while his legs might not be getting any younger, he would be keen to sign off his rugby career testing himself against "the best" regularly throughout such a campaign.
The likelihood of the Irish centre coming to Australia has been given more concrete considering the recent recruitment of former Leinster coach Cheika to the Waratahs, while NSW have made it clear they are in the hunt for a high quality overseas marquee player - with the Australian franchises allowed to sign two such players - as long as one is within a development framework with the potential to represent the Wallabies.
Cheika took over in Sydney on September 18, and told AAP that any move could be a couple of years away considering at this point O'Driscoll is signed with Leinster until June 2013.
"Obviously I know Brian very well," Cheika, who won a Heineken Cup with O'Driscoll, said.
"It is no secret that he is one of a number of top players over there who would love to come down and play (in Investec Super Rugby)."
"I saw him before I left, I went to say goodbye.
"But we haven't spoken since. I wouldn't want to do that to him or the club. He is in the middle of a season, the Heineken Cup is still on and they are focusing on that.
"It is still my club and it is very close to me and I would not want to disrupt their season. That is Brian saying how he feels about things and what he might like to do. It would be a big decision for him to leave Ireland but the thought is there with all the top players they would all love to come down and have a try, there is no doubt about that.
"We don't have a marquee player (at the Waratahs)," he said.
"Whether we would go down that road is something we would have to discuss."
