Bali: Prime Minister Tony Abbott is facing an Indonesian social media backlash over his linking of $1 billion in tsunami aid to the mercy campaign for Bali Nine death-row inmates Andrew Chan and Myuran Sukumaran, with a campaign urging people to collect coins to return to Australia.

On the streets of Indonesian cities people were asking motorists and passersby for spare change. Meanwhile, social media users were posting pictures of the money they had gathered and hurling insults at Mr Abbott and Australia.

Many also expressed their support for death by firing squad for Chan and Sukumaran.

The twitter campaign, using the hashtags #KoinuntukAustralia, #coinforAustralia and #coinforAbbott and growing rapidly in popularity, highlights how Mr Abbott's remarks have backfired badly in the country.
