The International Cricket Council is set to review its punishment for ball-tampering in light of the Australia cheating scandal.
Cricket Australia has banned Steve Smith and David Warner from international and domestic cricket for a year while opening batsman Cameron Bancroft was exiled for nine months over the incident during the third Test in South Africa.
The ICC were unable to impose more than a full-match fine and a one-Test ban on Smith under its current code of conduct.
Richardson said a wide-ranging review, likely to be informed by respected former players such as Allan Border, Anil Kumble, Shaun Pollock and Courtney Walsh, would be an opportunity to "draw a line in the sand".
"With the full support of the board, we'll be undertaking quite a wide-ranging review into player conduct -- and in particular the spirit in which the game is played," he said.
"We want member countries, across the board, to be more accountable for the behaviour of their players -- take responsibility for it."
