AusPost says from you to me it should be "Delivered in up to 4 business days". So you posted it on Wednesday. So Thursday (1), Friday (2), Monday (3), Tuesday (4). So I should get it tomorrow, hoepfully.
Plus I sent my on Monday and you received the next Monday. So if you sent on Wednesday I should get it tomorrow.
that is very slow but yeah mate should DEFINATELY be tomorow. If it doesnt come by Thursday get onto me and i will chase it up or try and track down some more cards to send to you in replacement!
