The family of an Australian man sentenced to death for drug smuggling in China have asked friends not to speculate on his case.
Karm Gilespie was sentenced on Saturday and has 10 days to appeal the verdict.
"Our family is very saddened by the situation," his family said on Monday.
"We also request that friends and acquaintances of Karm refrain from speculating on his current circumstances, which we do not believe assists his case."
The prime minister says he is sad and concerned about the case.
Scott Morrison says Australian officials have raised his case with Chinese counterparts on a number of occasions and are still working to secure his freedom.
"I and the government are very sad and concerned that an Australian citizen, Mr Karm Gilespie, has been sentenced to death in China," he told parliament.
"Our thoughts are with him, his family and his loved ones."
Mr Morrison said the government would continue to support Gilespie and reiterated Australia's opposition to the death penalty.
Deputy Prime Minister Michael McCormack has highlighted the need for diplomacy in the case, rejecting assertions the penalty may be politically motivated.
"What we need to do is be very careful, and what we need to do is make sure that anything that's said about this matter doesn't affect Mr Gilespie's cause and case in any way, shape or form," he told the ABC.
"We want to make sure that we give him every available assistance and we are, through the proper processes."
Gilespie was arrested in 2013 with more than 7.5 kilograms of methamphetamine in his check-in luggage as he was about to board an international flight from Baiyun Airport, in the southern Chinese city of Guangzhou.
Foreign Minister Marise Payne reiterated Australia's strong opposition to the death penalty.
"We regard it as undermining shared human dignity and inconsistent with principles of criminal justice that allow for rehabilitation," Senator Payne said.
"The irrevocability of it allows for no errors of fact or law to be corrected. It is no more effective as a deterrent against serious crime than lengthy imprisonment.
"We advocate consistently for the abolition of the death penalty worldwide, via every diplomatic avenue available to us."
Gilespie had worked as an actor before turning to investing, motivational speaking and business coaching.
