Nurse Jacintha Saldanha was found dead in a suspected suicide last week after transferring the call in which Greig and Christian pretended to be Queen Elizabeth II and Prince Charles to gain medical details about the hospitalised Duchess of Cambridge.
Media company Southern Cross Austereo has cancelled their popular Hot 30 show and Greig and Christian are serving a suspension in the wake of an immense backlash.
Southern Cross Austereo initially suspended its advertising, but has now announced that it will give ad proceeds through the rest of the year to a charitable fund setup in Saldanha's honour.
A minimum of AUD $500,000 (£325,000) will be made to the memorial fund, and advertising will return to the station this Thursday, December 13.
SCA chief executive officer Rhys Holeran said: "We are very sorry for what has happened. It is a terrible tragedy and our thoughts continue to be with our family.
"We hope that by contributing to a memorial fund we can help to provide the Saldanha family with the support they need at this very difficult time."
He added: "The company today reiterates that it is deeply saddened by this tragic and unforeseen event and offers its condolences to the family of Jacintha Saldanha."
Southern Cross Austereo has said it is confident that Greig and Christian broke no laws, but have suspended pranks until an internal review of company policy can be undertaken.
A company representative also hit out at the media this week, accusing the UK press of conducting "a witch hunt" as a result of the scandal.
