Bali Nine families visit on final days

The devastated families of Andrew Chan and Myuran Sukumaran are visiting the men in Kerobokan jail on what may be one of their last days there.

Sukumaran's mother, Raji, paused on her way in, to make another desperate plea for help.

"What is the difference between my son and these people overseas?" she told reporters.

"I don't want my son murdered. Please help.

"I don't know why they don't want to help my son when they are helping their people overseas."

Indonesia this week announced it was stepping up efforts to save its own citizens on death row overseas.

Most are convicted drug traffickers and murderers in Saudi Arabia and Malaysia.

The men's Australian barrister, Julian McMahon, was also visiting the jail, along with pastor Matius Arif and other local friends of Chan.
