Labor's Cressida O'Hanlon is expected to be confirmed as the next member of South Australian parliament when final votes are tallied in the Dunstan by-election.
The 51-year-old former political adviser took a 3.8 per cent two-party-preferred lead over her Liberal rival Anna Finizio in early counting on Saturday night, but must wait for pre-poll and postal votes to be tallied up to confirm her win.
