Australian police said on Tuesday that after an anti-terror raid, a 16-year-old girl has been arrested alongside a man, 20, over allegedly sending funds DAESH terror organisation.
"We anticipate that both these people will be charged later today and attend court and the charge that we anticipate they will have is one of financing terrorism," New South Wales State Police Deputy Commissioner Catherine Burn told reporters.
"We will be alleging that they were involved in obtaining money to send offshore to assist the Islamic State (DAESH) in its activities," she said.
Australia's anti-money laundering agency stated in November that the reports showed suspected funds being sent to terrorist groups had tripled in 2015. At least $50 million ($38 million) could have been sent to DAESH.
Officials believe several Australian citizens have gone to Syria and Iraq to fight alongside DAESH.
Authorities say they have prevented many potential attacks, while there have been a number of "lone wolf" assaults.
Australian Federal Police Deputy Commissioner Michael Phelan indicated the recent arrests were not related to any threat of an impending attack in the country.
"The charges these two people are expected to face relate to their alleged activities in raising funds and attempting to transfer those funds to an overseas terrorist organisation," he said in a statement.
Both are expected to be accused of financing terrorism and will face a maximum penalty of 25 years in prison.
According to officials the man was previously arrested in Australia's largest counter-terrorism raids in September of 2014.
NSW Police Deputy Commissioner Catherine Burn repeated her concerns about the girl's young age.
"I previously said that it was disturbing that we continue to deal with teenage children in this environment. And today's arrest hasn't altered that position," she told reporters in Sydney.
A 15-year-old boy was also arrested in December as part of Operation Appleby.
