The trio are contracted, however, coach Dean Laidley said deals could be done for any of them if the price was right.
Harris is the only one who has expressed a desire to leave Arden Street.
"There were lots of names mentioned," Laidley said.
"Hamish McIntosh's name was mentioned today, so even with Hamish we'll sit down and if there's real interest there and a club loves Hamish, we'll have a look.
"Until we have a look and get some sort of offer somewhere, you can't really speculate because it's that type of week."
Laidley also said there were no offers for Jones or Harris so far.
"The two players that we're talking about are contracted, and until someone actually puts something on the table, they're our players and they'll be playing with us next year," Laidley said.
Laidley refused to divulge the club interested in McIntosh.
The Kangaroos would prefer draft picks for their players in the last uncompromised draft before the Gold Coast team enters the fray.
"We'd like to get a few more picks, but if not, we'll keep our contracted players and take the picks we've got and move on," he said.
Laidley said all three players remained required, and would not be disappointed if the club didn’t trade them.
"I'm not wishing there's any offers for them," he said.
"We've contracted them; we want them to stay. Daniel is the only player who has stated that he would like to leave, Corey Jones has attracted a little bit of interest, and same with Hamish.
"If I was a betting man, most if all will still be at our footy club by the end of the week, and that's the way it goes.
"There's a lot of innuendo and that's what happens at this time of the year with trade week."
Laidley also confirmed the Kangaroos had no interest in premiership player Ryan O'Keefe, who has sought a trade to Melbourne-based club from the Sydney Swans.
