@Wayne ******
further to what Tod said, after following this site for 2 years in preparation for my retirement later this year, I am led to believe that the Thailand authorities want to see your pension deposited each month , apparently centrelink close over the Xmas period and pay 2 months( December and January) in 1 hit, this situation apparently is unacceptable and could cause you Visa problems, I will watch your post to see if anyone has a solution, Cheers and good luck
