6 Month Passport Validity Requirement for Transit Through Guangzhou

Dear Sir or Madam,

My Australian passport will expire on September 27th 2016, I will be flying off to Osaka through Guangzhou on the coming March 25th and through Guangzhou again back to Sydney on April 2nd, will I still be allowed to TRANSIT through China as my passport validity will be just a little shorter than 6 months on the date of return to Australia in April?

Appreciate your advice!
