I'm unable to attach payoneer for payouts to my eBay Australia seller Account.

You cannot. To sell on eBay Australia, you’re required to be registered for Managed Payments. eBay receive the payments, and - subject to the seller having fulfilled the requirements - will disburse the funds to the seller’s verified Australian bank account. Seller must have their bank account verified and their ID (including submitting photo ID) verified. https://www.ebay.com.au/help/selling/getting-paid/registering-seller?id=4792
