Hi Tearose
Just put a question on about aged parent visa, first time I have posted and just noticed this thread. Wow a bit shocked at the response you got!! I think I will steer clear but if this helps I have some although limited knowledge that might help. Maybe your mother could come out on an aged parent visa as she has at least half of her children here. The options appear to be the non contributory parental visa (804)or the contributory parental visa (864). The departments website is fairly informative. My in laws came out on the non contributory visa , they think its the best decision they made and are very happy here, they have been here for 2 years. My Mum is now looking at her options as she has 2 of her 3 children here, she is 76. She has recently sold her home so will come out soon and then make the decision. I think its a great opportunity for them with better climate and family support but of course their decision at the end of the day.
