Two men are set to face court later this month over the incident.
CCTV footage appears to show two men entering a Southport tobacconist and allegedly stealing sunglasses.
The owner moves to confront them and is allegedly attacked with repeated punches, and stomped after he falls to the ground.
The two men then allegedly take the gold chain from around his neck, a piece worth $9500.
The shopkeeper gets up to go after them, minutes before police arrive.
Two men, aged 18 and 27, have been arrested over the incident and are set to face court later this month.
The shop owner was released from hospital this morning and is already back at work.
He has reclaimed his golden chain, but said he probably would not be wearing it to work again.
