A Brisbane father of three has been jailed for fraudulently claiming disaster relief funding for flood and bushfire victims.

Ruel Neil Patrick Fogarty has pleaded guilty in the District Court in Brisbane to obtaining and attempting to obtain a financial advantage by deception.

Prosecutor Heather Cunningham said the 26-year-old made false claims for $1,000 relief payments made available to the victims of flooding in north Queensland and bushfires in Victoria in 2009.

He claimed a total of $33,000 but was paid $20,000.

Fogarty's lawyer Terry Fisher said his client claimed the money to feed his drug habit.

Judge Richard Jones described Fogarty's actions as abhorrent and despicable.

He sentenced the father of three to two and a half years in jail, to be released after nine months.

The sentence starts in March after Fogarty serves the rest of a suspended sentence for previous offences.
