(Reuters) - Austrians choose a new parliament on Sept 28. Here is a brief description of the electoral system:
— Austria is divided into nine constituencies matching the federal states (Bundeslaender), which in turn are subdivided into 43 electoral regions.
— To secure a place in parliament, a party needs either to win four percent of votes across the country, or a set share in one of the 43 electoral constituencies (20-25 percent depending on the region).
— The 183-seat Austrian parliament, the Nationalrat, is elected every five years by direct popular vote in a system of proportional representation.
— Voters choose a political party but can at the same time give one candidate of the party a preferential vote and influence their ranking on the list.
— About 6.1 million Austrians are eligible to vote out of a population of around 8.4 million. The minimum voting age is 16.
— Most polling stations open at 0700 (0500 GMT) and close at 1700 in major cities. Polling stations in rural areas close in the early afternoon.
— Austrian news agency APA and state broadcaster ORF release their first projection based on actual results of already counted polling stations at 1700 (1500 GMT). The final result is expected at 1930.
