Nab Casino withdrawals and KYC: how smooth is it?

Withdrawals are the part that decides whether a casino is worth my time, so I'd like to hear from members about Nab Casino. It holds a Curaçao licence, which is fine, but a licence doesn't tell me how the cashout actually goes in real life.

What I'm mostly curious about is the verification step. Do they ask for ID and proof of address straight away at signup, or only when you request your first payout? And if you send the documents, is it sorted within a day or does it drag on for a few days with more requests?

Since a lot of the interest in this brand seems to come from Australia, I'd especially like to hear from players there, but anyone from the UK, NZ, Canada or elsewhere is welcome too. What was your timeline from request to money in your account, and did the first withdrawal go differently from later ones?
