Hi - I normally use the e651 free visitor visa to visit Australia from the UK for any 3 month period within twelve months. However i am planning to apply for the subclass 600 for a single 6 months visit and wanted to immediately apply for the e651 visitor visa once I leave Australia as it provides more flexible over any twelve month period. Are there any restrictions on me doing this as most of the topics on this subject relate to multiple trips of 6 months with not more than 12 months stay in any 18. Thanks from PJ
