Succarieh not remorseful, appeal told

A Brisbane Islamic bookshop owner jailed for sending money to foreign fighters in Syria should have been given a harsher punishment, an appeals court has heard.

Omar Succarieh covertly sent more than $57,000 to his brother Abraham Succarieh and three other men who were fighting against Assad regime forces in Syria.

Succarieh also gave $7700 to an Australian-born citizen of Albanian descent and Muslim Sunni faith to travel overseas in an alleged attempt to join the fight.

The 33-year-old last year pleaded guilty to four foreign incursion offences after the federal public prosecutions department dropped more serious terrorism-related charges.

Supreme Court Justice Roslyn Atkinson sentenced him to four and a half years' prison with a non-parole period of three years, making him eligible for release in late 2017.

Prosecutors have appealed against the sentence and argued in the Court of Appeal on Tuesday that the punishment was "inadequate" given the seriousness of Succarieh's actions.

Commonwealth prosecutor Sarah McNaughton SC said Succarieh's apparent lack of remorse meant there could be no confidence that he had changed and would consider the Australian community as being above religion.

"He really has failed to properly acknowledge that he knew at the time that the activities were criminal," Ms McNaughton said.

Barrister Soraya Ryan said Succarieh, who is also appealing for a lesser sentence, had shown remorse in a letter written to the court at the November sentencing.

The Court of Appeal reserved its decision for a later date.
