The name Gosford has existed as an electorate since the 1950 election.
The seat covers 867.15 square kilometres, including postcodes 2083, 2250, 2256, 2257 and 2775.
People can vote early at the Gosford Gateway office, opposite the train station, from 8am until 6pm Monday to Friday, with the office open two extra hours on Thursday night.
There are 12 early voting reasons outlined by the NSW Electoral Commission but no evidence is required to be produced.
The reasons include being at work, caring for someone, and the belief that attending a voting centre on election day would place you at risk.
Polling booths will be available at Brisbane Water Secondary College-Umina campus, Brisbane Water Secondary College-Woy Woy campus, Ettalong Public School, Pearl Beach Community Centre, South Woy Woy Progress Association Hall, Umina Beach Public School, Umina Community Hall, Umina Uniting Church and at Woy Woy South Public School.
