Smith broke the news to his teammates soon after he learnt he would be rubbed out for a year.
Players were visibly upset. Smith and Paine embraced in the team hotel and moments later Smith left for the airport.
He has been stripped of the Australian captaincy,which is being taken over by Paine on a full-time basis.
The decision of the CA board and Sutherland completes Smith's stunning fall from grace from golden boy to one of the masterminds of one of Australian cricket's lowest ever moments - and all in the space of four days.
Smith took his medicine and in a sign of how eager he is to try and rehabilitate his image,he will front a press conference at Sydney airport upon his arrival to Australia.
The 28-year-old has been deeply shaken about how it has all gone off the rails for him so swiftly.
The level of the sanctions means that Smith and Warner are completely ruled out until after the next Australian home summer,paying a heavy price for their ill-fated decision to bring a foreign object onto the ground to try and alter the condition of the ball during the third Test against South Africa.
The players have been banned from all elite Australian cricket for 12 months,although they can play grade cricket.
The length of the suspensions mean that the next major event that Warner and Smith could play in for Australia is the World Cup,followed by the Ashes,in England next year.
The BCCI had waited for CA to deliver the penalties and less than two hours later announced via press release that Smith and Warner were banned from the tournament this year.

Bancroft,meanwhile,received a slightly lesser punishment. He will sit out nine months after being the player who used sandpaper - which was originally claimed to have been tape - to work the ball before being caught out hiding it down his pants.
However,given he was only a new member of the team,the long absence from the side could have a major effect on his Test future.
Bancroft has also technically been banned from leading the team until a year after his suspension runs out.
An investigation led by CA head of integrity Iain Roy had concluded that only three players had prior knowledge of Australia's ball tampering in Cape Town.
The CA board assembled via a telephone hook-up for more than three hours on Wednesday to consider the penalties.
The players have seven days to respond to the charges.
