Silver is virtually useless except for the 25% miles bonus on SQ metal, on some booking classes. And even those bonus miles do NOT count as status miles, so it's not like you are going to get Gold any easier.
Overall, KrisFlyer is a very poor and substandard FFP unless you spend a lot in Singapore using a credit card and generate miles this way. And if you have a family and travel together often, then even if you fly SQ you are better off crediting all flights to Virgin Australia's Velocity scheme that allows for family pooling of miles (and STATUS credits too!).
