The plan of two Australian teenage brothers to supposedly head to the Middle East to join the Islamic Militants (ISIS) was foiled after they were blocked at the Sydney Airport.

Border Protection Minister Peter Dutton said the two brothers, who were aged 17 and 16, were detained on Friday afternoon.

Dutton did not give more details about the trip of the teenagers, except to say they had wanted to go to a Middle Eastern "conflict zone".

He also declined to reveal the items found in their luggage that had prompted the airport security personnel to summon their new counter-terrorism unit.

The names of the two young men are being kept confidential as they are still minors.

The Australian Broadcasting Corporation reported that the boys were eventually turned over to their parents, although they will still face investigations.

Reports said an 'extremist paraphernalia" was found in the brothers' belongings.

A letter supposedly containing the guidelines on how to trick the authorities and come up with a fabricated story on the purpose of their travel was also discovered in their luggage.

Journalists also reported that the brothers were on their way to Turkey, which is a common transit point for people heading toward Syria, to meet up with the members of the ISIS.

Dutton emphasized, "the two young men are kids, not killers. They should not be allowed to go to a foreign land to fight, then come back to our land, eventually more radicalized".

He notes that the teenagers' parents were shocked to find out about their children's attempt to leave the country.

The two were reportedly influenced by what they read on the internet. No details are being given on who was financing the young men's flight.

"The two misguided young Australians, Australian-born and bred, who went to school here, imbibed our values, and yet it seems they had succumbed to the lure of the death cult," said Australian Prime Minister Tony Abbot.,

He noted that the two brothers were "on the verge of doing something terrible and dangerous".

Abbot is relieved authorities were able to prevent them from leaving the country.

Australian investigators are set to file charges against the boys.
