we are talking about extension only. it is simple to understand how it should work. Once you get extension, from the date of extension, if you use monthly income method, you have to keep it till the next extension ( 12 months ) that was agreed by you and immigration. And if you want to change it to 800K deposit method, do not forget what you agreed at the last extension. yes monthly method for 12 months. so you must keep this and in the mean time you put 800K. then at next extension, you have two methods. monthly and 800K deposit both. then you can change to 800K deposit method. And for next extension, you also have to keep the rules of 800K deposit method. again, the signed and agreed rules from last extension must be kept on till next extension.
