Terror funders are complicit in deaths: PM

Australians who fund terrorists are complicit in their "dreadful deeds", Prime Minister Tony Abbott says.

Victorian police have charged a 23-year-old man with intentionally providing funds to a banned terrorist group.

It's alleged the man, arrested in raids on Tuesday, sponsored another man to fight in Syria.

"Anyone who supports terrorists is complicit in the dreadful deeds they do," Mr Abbott told parliament on Tuesday.

He said the anti-money laundering agency Austrac had been given an extra $20 million to help track down terrorist funding.

Federal cabinet has yet to give final approval for a combat mission in Iraq to fight Islamic State.

But Mr Abbott said that subject to cabinet consideration "our objective is to support governments that don't commit genocide against their own people, nor allow their territory to support terrorism against our people".

ASIO will brief state and territory attorneys-general and police ministers at a meeting in Geelong on Friday on the national security threat.

Australian Federal Police officers will also brief the meeting on recent raids.
