Especially application or say passports of many of the Travellers applying or residing in South India provision faces same problem for every visa application which is made. Also the Immigration/Visa Officer issuing the visas also knows the issues faced, and therefore when you apply for the Australia visas and as per their rule for filling the form is that you need to fill all the information as per your passport only which for your case will be Family Name________ (It should be Blank as in your passport there is no Surname mentioned of yours) and in Given Name - mention your given name as mentioned in passport, because you get the visa as per your passport data mentioned only.Just to inform you that every country has their own processing and terms and conditions for visa application wherein they have different procedure and way of mentioning details in the form ex:- if you apply for USA visa with the same passport where your surname is blank there your Given Name needs to be mentioned in Surname and Given name in form needs to mention is FNU (First Name Unable).So in your case it would be as below:-Family Name - Remains Blank.Given Name: Mention as per your passport.I hope above information satisfies your query.Regards.Vinit Chandele
