The Liberal Party has claimed victory in the NSW seat of Manly, one of three electorates where by-elections were held on Saturday.
Voters took to the polls in Manly, North Shore and Gosford.
Labor claimed victory early in Gosford, where former paralympian Liesl Tesch will become the new MP, with a swing towards Labor of more than 10 per cent.
That result was expected; but the outcome was less predictable in the safe Liberal seats of Manly and North Shore.
All week, NSW Premier Gladys Berejiklian had been saying she was bracing for significant swings against the party in both seats, pointing out there was usually a backlash against the sitting Government in a by-election.
She can breathe a sigh of relief over one seat; the Liberals have retained Manly, with former deputy mayor James Griffin securing 43 per cent of the first preference vote.
That is a 24 per cent swing against the Liberal party, based on the votes that have been counted so far.
Mr Griffin is replacing former premier Mike Baird who served as Manly MP for 10 years before quitting politics in January.
The seat of North Shore will be harder to call.
There, the issue of forced council mergers was expected to drive Liberal voters to independent candidates, the most prolific being Mosman councillor Carolyn Corrigan.
The ABC’s election analyst Antony Green said his Liberal party sources were quietly confident of retaining North Shore, but may not claim victory tonight.
At the moment, the Liberal candidate Felicity Wilson has secured 40 per cent of the first preference count; a 17 per cent swing against the party.
Ms Wilson faced criticism in her last week of campaigning, admitting she wrongly claimed she had lived in the electorate for 10 years.
