Thousands are expected to attend public funerals for Bali nine ringleaders Andrew Chan and Myuran Sukumaran in Sydney this week.
The two men were executed alongside six others by an Indonesian firing squad on the prison island of Nusakambangan last Wednesday.
Their deaths came after they spent almost 10 years on death row in Bali's Kerobokan prison.
Sukumaran's family announced the details of his service "to farewell and celebrate the life of their son and brother Myuran".
The service will be held at DaySpring Church in Castle Hill on Saturday at 11am and is expected to finish at 2pm.
Sukumaran's mentor and artist Ben Quilty will speak at the service along with family and close friends.
After the service, there will be a private cremation, which will be for immediate family and friends only.
Chan's funeral service will be held at the Hillsong Church in Baulkham Hills on Friday at 11am.
A Hillsong spokesman said the service would be conducted by Salvation Army minister and Chan's spiritual mentor David Soper.
Both families have invited members of the public to attend the ceremonies.
The bodies of Chan and Sukumaran arrived in Australia on Saturday.
On Monday, Australian Federal Police Commissioner Andrew Colvin said he could not guarantee Australians caught smuggling drugs in countries with the death penalty would not suffer the same fate as Chan and Sukumaran.
During a media conference to explain the AFP's involvement in the arrests of the Bali nine, Mr Colvin said police did not have enough evidence to arrest any of the members before they left the country in 2005.
"If there is to be a message out of these executions that we saw last week ... I sincerely hope it is that other young lives are saved by people thinking twice before participating in serious crimes overseas," Mr Colvin said.
Chan converted to Christianity after his arrest for attempting to smuggle eight kilograms of heroin to Australia.
He studied to become a pastor, and ran a regular church service at Kerobokan prison.
Sukumaran mentored other prisoners, taught English and ran computer, graphic design and art classes.
He became a proficient painter and was studying for a Bachelor of Fine Arts by correspondence through Curtin University, which he was due to finish at the end of the year.
