Gold Coast man bashed with block of wood

A man has suffered a head injury after being beaten across the head with a block of wood in a botched Gold Coast robbery.

The man was walking on a bush track in Upper Coomera just before 7.30pm on Friday night when he was attacked.

The victim fell unconscious for a short period and woke to see a man trying to steal his wallet.

He managed to fight off the offender before being taken to the Gold Coast University Hospital with a minor head injury.

The thief is described as being Caucasian in appearance, around 175cm tall, with a stocky build and dark, long, wavy hair.

He was wearing dark jeans and a hooded jumper.
