I would buy grain in bulk, it's always a good idea for base malts at least, except it costs twice as much to get it to Darwin than it does to actually buy the malt. You'd think chucking 25-50 kg of grain on a truck would be cheaper than sending it via Auspost or something. Apparently not.
Incidentally, if anybody knows a reasonable way of getting bulk grain to the middle of nowhere (Perth, Darwin, etc), let me know! As long as it ends up cheaper than buying extract I'll be happy.
Slash,
no problems getting grain in perth mate. Not sure how Darwin fares. Sounds bad though
