Indonesia is yet to name a date and place for the executions of two Australians, who are now officially in line for the firing squad.

The Indonesian President's denial of clemency to drug trafficker Andrew Chan came two weeks after fellow Bali Nine ringleader Myuran Sukumaran received the same news.

Indonesia plans to execute both men together, but a date hasn't yet been scheduled.

The pair's lawyers are preparing to file for judicial reviews of their cases, but whether the application is admissible depends on a legal dispute over how many reviews can be sought.
