Posting a frame?

Just wondering what is the best way i can pack a frame and post to someone? I sold my frame along side with some other parts like handle bars. could i just go to the post office and do it there? anyone recommend anything? and approx hw much from syd to canberra? i have never done this before that’s all


quick search yielded these results. there’s fuckin heaps on here already.

edit - how much you end up getting for your bike? couldn’t find the listing…
