Australian Resident, Irish Passport

Myself and my fiance are Irish citizens with Irish passports but are currently residing in Melbourne, Australia where we are residents on 457 work sponsored visa. We are returning to Ireland next week to get married there. We will be in Ireland for a total of 2 weeks. We are going to Hong Kong on our honeymoon on the way back to Australia and would like to apply for a visitor visa for mainland China (for shopping/tourist purposes). We are planning on applying for the Chinese tourist visa from Ireland. We will send our passports and completed documents off as soon as we get back. Is there any additional information we need to supply? Our Australian visa'a are electronically tagged to our passports but we do have the email confirming that we hold Australian 457 visa. Should we supply this in addition?
