By . Emily Crane . and Sarah Dean . Taxpayers could be forking out hundreds of millions of dollars a year so security agencies can properly monitor Australian jihadists returning from conflicts in the Middle East. Surveillance costs are expected to tip $8 million for just one jihadist as intelligence teams monitor the 150 or so Australians who may return home having been suspected of fighting in countries like Syria and Iraq, the Australian reports. The high spending comes as police and surveillance agencies prepare for potentially the largest monitoring operation in Australia to stop suspected fighters becoming home-grown terrorists.

Khaled Sharrouf, from Sydney, is thought to be fighting with al-Qaeda off-shoot Islamic State of Iraq and the Levant . The $8 million sum would reportedly cover eight-person surveillance teams working on five different rolling shifts for the entire year. It also includes transport and high-tech surveillance equipment. It comes as the federal government announced an additional $600 million in counter-terror funding this week for five different agencies, including the domestic spy agency ASIO and the Australian Federal Police. While security agencies will not reveal specific target numbers or spending figures, it is expected that some of the extra funding will be spent on this extra and expensive surveillance. 'The important thing here is to give us the tools that we need to ensure that people who are a serious threat to our country are appropriately dealt with,' Prime Minister Tony Abbott said this week.

The funding came as an Australian jihadist posed with decapitated heads and supposedly gave advice on how people could access deadly explosives in Sydney on Twitter. Mohamed Elomar, who is wanted by the Australian Federal Police for his activities in the Middle East,  renewed his social media attack on his former home country on a new Twitter account after his previous one was shut down last week. The 30-year-old invited wannabe jihadists in Sydney - the city where he was born - to contact him if they want to get their hands on dynamite and grenades. 'Anyone in Sydney who is after explosives (dynamite sticks, C4 sticks, orica mine sticks, grenades ) lots more. If interested DM me,' he wrote.
