Setting up broker account from overseas

I have issuer-sponsored ASX shares that at some point I will want to sell, so want to transfer them to a broker account.

I’m not an Australian resident and don’t have an Australian bank account – I’d probably want the sale proceeds to go to an account in either the UK or Singapore. Setting up a broker account without an Australian bank account or proof of residency seems difficult so far. Just wondering if anyone here has had similar experiences or knowledge?

Thanks
