Brought up in another culture, I'm not entirely sure about the Australian way of accepting reward when you found something valuable and returned to the owner.
What would you do as the founder? Do you expect to be rewarded because it's a social norm? Do you need to at least pretend like you don't care about the reward?
What would you feel as the owner? Are you reluctant to give reward but feel obliged? How do you judge how much to reward the founder? Would you feel offended if the founder rejects your reward?
Thanks in advance for your input!

Can only speak from my own experience. I am happy to return an item without a reward. As cheesy as it sounds, their happiness is generally enough for me to feel good.
If I had lost an item and it was returned I would most likely offer a reward. If I offer it, it makes me feel good if you accept it. Would not be offended if you didn't take it, but would prefer you did,
