Arrested man 'plotted Qld terror attack'

A man arrested in Queensland raids was allegedly plotting a terrorist attack in the state.

Raids on homes in Brisbane and Logan early on Thursday were linked to simultaneous raids in Sydney from which one man was charged over planning to execute a member of the public.

The latest counter-terrorism operations came eight days after two men were arrested in southeast Queensland.

"It may now be alleged that at least one individual was contemplating onshore terrorist action," Premier Campbell Newman said.

Police Commissioner Ian Stewart said new information had emerged since last week's Queensland arrests, leading to Thursday's raids.

"Since that time, we've come into possession of information, quite disturbing information about the intention of at least one of the people presently in custody in this state," he said.

Mr Stewart said the swiftness of the raids had averted a tragedy on Australian soil.

"It has been very, very timely for Australia," he said.

One of the men arrested last week, 31-year-old Omar Succarieh, was denied bail in the Supreme Court in Brisbane on Thursday, following a charge of funding Syrian extremist group Jabhat al-Nusra.

Agim Kreuzi, 21, is allegedly linked to the jihadist group Islamic State and is also accused of preparing for incursions into Syria.

No one was arrested in Thursday's three Queensland raids, in Mount Gravatt East, Logan and Underwood, where an Islamic centre was raided last week.

However, 15 people were detained following the NSW raids, with one man charged in Sydney with terrorism-related offences.

Mr Stewart said there was a link with the pre-dawn raids in Queensland and NSW, and Sydney court appearances on Friday would show the connection.

"Absolutely, there is," he said.

The premier said the risk of harm from a small number of people did not justify the vilification of Muslims, and urged people from other faiths to visit a mosque on an open day.

"If anybody uses what's happened to vilify any group, any race, any religion, essentially, ladies and gentlemen, they are playing into the hands of these terror groups, these would-be terrorists," Mr Newman said.
