Australian referees appointed to WC quarter final

Hyundai A-League referee Ben Williams' impressive maiden World Cup campaign has continued after he was appointed as the fourth official for the quarter final match between Argentina and Belgium.

Williams made history in Brazil on Monday morning by becoming the first Australian to take charge of a second round match at the FIFA World Cup - Costa Rica's penalty shootout victory over Greece. 

The 37-year-old had already overseen two matches at the tournament, having taken charge of Ecuador's 2-1 win over Honduras and Belgium's 1-0 win over the Korea Republic.

He has previously officiated at the 2012 Olympic Games and was in charge of the 2012 AFC Asian Champions League final between Ulsan Hyundai and Al Ahli.

Williams' assistant Matthew Cream has been appointed as the standby assistant referee for Sunday morning's match.
