Islanders off Donegal will go to the polls today, two days before mainlanders cast their votes.
The Islands off Donegal form part of the Donegal South-West constituency.
760 ballot papers have been carried to polling boxes in Arranmore, Tory, Inishbofin, Inishfree and Gola.
Ferries and small boats have carred 523 papers to two polling booths on Arranmore, 25 on Gola and nine to Inishfree.
An Air Corps helicopter will carry 136 to Tory and 67 to Inishboffin.
There was a massive swing against Fianna Fáil when the electorate on Arranmore went to the polls in the Donegal South-West by-election.
The islands had a turnout of just over 50% in the by-election.
There is expected to be a slightly larger turnout of voters for the General Election today.
