dear god, are they still playing normal antes in Sydney? BB ante people! spare us!
line seems OK. we're not folding AA here and given you've posted it sounds like you've minimised the loss
a more standard line might be 350 otf.
be aware that a competent V might c/r to 800 with hands like 97s with bdfd that can improve and barrel large ott. if you're not comfortable playing your value range against such a line, then checking back flop and allowing V to barrel a couple of streets is fine.
there are exploit folds potentially against the nittiest of opponents, but you're up against a random here who can certainly put pressure on with worse, so cc call call is a perfectly valid line.
sorry he had Tx
