Two men have been charged after a police raid on Burton Island - off Western Australia - allegedly found Antoine Dicenta, 51, and British man Graham Palmer, 34, with 1.087 tonne of methylamphetamine, cocaine and ecstasy in bags they had tried to hide under seaweed.

However, when they are said to have attempted to flee the scene the huge animal blocked their paths.

Geraldton volunteer marine rescue service vice commander Damien Healy told ABC radio: ''They woke it up and it jumped up with its big chest out and bellowed at them.

''The guys basically had the choice of going through the seal or getting arrested and they ended up choosing getting arrested.''
