Centrelink valued my FIL's home at $100,000 over the actual value. No amount of requests have made them change their mind as his assett test is what his nursing home fees are set at.

They will need to do a reassessment now that it has been sold though. I hope he has nothing left at the end of his life, it's his money, he deserves to have it spent on him. His children have had ample opportunity to amass their own assetts.
