Hi, thanks for the post, we submitted our visas via our son, he posted them by courier from Perth to the visa office. They were signed for on June 15th so far we haven't had any acknowledgement and the 1st payment hasn't been taken yet, hopefully that will happen soon and we will be charged the amount that was showing in June 2014 prior to any price increases they may make this month. Not considered selling house yet but that may change, was looking at taking a new 2yr fixed rate that will considerably reduce monthly payment.
PS we are both 50 , life begins now an all that lol
