Due to the hundreds of thousands of possible different pieces and colours available in the LEGO® range, it is virtually impossible for a normal retailer to take care of missing parts. LEGO as a company takes responsibility for this and can help you resolve any missing parts you may have in your new LEGO set.
These are two best options:
INTERNET: Fill out the form online here - http://service.lego.com/en-us/replacementparts
PHONE: Call LEGO Australia's customer service line on 1800 823 757. Why? LEGO® Australia services missing parts from new sets because it is virtually impossible for retailers to keep the thousands of parts necessary to help customers with missing parts from sets.
