My Wife has got Visiting Visa for Australia whose validity is for 1 year got Visa stamping in Sep-17 valid till Sep-18. But every stay is for 3 months maximum but can make multiple entries with in the year. In order to get her stay extended, is it fine if we can just go to any other country like Malaysia/Singapore/New Zealand etc. and can get three months extension on her stay in Australia without paying anything, and is there any rule to go my native place to get the stay extended. Please clarify.
