Smith and Warner made their return to the game at a Global Twenty20 tournament in Canada in late June while Bancroft played a low-level limited-overs event in Darwin.
The scandal, which rocked the sport, had far-reaching consequences in Australia with a clean-out of top executives from CA after a scathing review blamed its "arrogant and controlling" culture as partly contributing to players bending the rules.
"The ACA regards CA's decision as disappointing. CA maintains that both the length and nature of the sanctions remain an appropriate response in light of the considerable impact on the reputation of Australian cricket, here and overseas", Eddings said.
Additionally Warner was ruled out by CA to ever hold a leadership position in the national team again and Smith cannot to be considered for captaincy for another 12 months after serving his suspension.
"We have reconsidered the sanctions as they apply to each of Steve, David and Cameron in light of the ACA's submission and the Ethics Centre Review and recommendations".
Eddings said their decision should be recognised as a bookend to any further debate about the length of the bans on the three cricketers. That is also two days after the domestic Sheffield Shield Final - this Australian summer's final scheduled match.
"We believe the ongoing conversation about reducing the sanctions puts undue pressure on the three players - all of whom accepted the sanctions earlier this year - and the Australian men's cricket team", Eddings said in a statement.

"Steve, David and Cameron are working hard to demonstrate their commitment to cricket and have our continued support to ensure their pathway to return is as smooth as possible", Eddings said.
"As such, the Cricket Australia Board doesn't intend to consider further calls for amendments to the sanctions". "Let them play. I add that the ACA will be relentless in pursuing this end", ACA president Greg Dyer said.
"CA maintains that both the length and nature of the sanctions remain an appropriate response in light of the considerable impact on the reputation of Australian cricket, here and overseas", he said.
Cricket Australia have announced that they will not reduce the bans given to the ball-tampering trio despite pleas from the Australian Cricketers' Association.
However, the ACA said they "respectfully disagree" with the decision.
Former Test captain Smith, his vice-captain Warner and batsman Bancroft were handed the bans from worldwide and state cricket after the ball-tampering scandal in South Africa earlier this year.
"The ACA has done all it could in support of our submission, and now considers the matter closed".
