Can owner of multiple units vote if levies on 1 unit are unpaid?

If the levies for one or more units are paid, the owner can vote at the AGM in respect of those unit entitlements.

But beware of Cheques, B Pay etc ….. they may be problematic.  See here: https://www.lookupstrata.com.au/nsw-owner-unfinancial-levies/  

Many strata managers and secretaries will refuse to accept any payment at the actual meeting unless it is in cash or by bank cheque.  It is too easy for a delinquent owner to offer a cheque and then cancel it once the meeting has been held and theiir votes have been cast.

Some strata managers won’t clear debts until the money is in the OC’s bank account (especially if the late payer is the treasurer). If anyone has an issue with this, you can point out that the timing of the payment is their choice and they have had plenty of opportunity to put things right.

You should also make sure the multi-unit owner is being charged penalty interest.

And to add to ScotlandX’s comment, the multi-unit owner can only vote the Unit Entitlements of the properties whose debts have been cleared. If they do make a payment, it has to be directed to the account for a specific unit and they can then vote as the owner of that unit, and that unit alone.
