Indonesia's supreme court has imposed the death penalty on four of the 'Bali Nine' convicted Australian drug smugglers, an Australian newspaper has reported.

The court is said to have handed down the heavier sentences after an appeal by prosecutors.

The Australian government said it had yet to receive confirmation of the report.

A supreme court official in Jakarta said four of the nine appeals had been decided.

A court spokesman, Djoko Sarwoko, told Australia's The Age newspaper "those with life sentences have had their sentences increased to death".

Tan Duc Than Nguyen, 23, Si Yi Chen, 21, and Matthew Norman, 19, were arrested together at the Melasti Beach bungalows in Bali and sentenced to life at their original trial, but that was later cut to 20 years by the island's high court.

Prosecutors then appealed to the supreme court, which - according to The Age - has now given them the death penalty.

The paper said the death penalty had also been handed to 20-year-old Scott Rush.

Prosecutors did not appeal against a 20-year jail term for the only female member of the group, Renae Lawrence.

Andrew Chan and Myuran Sukumaran had already been given death sentences.
