The majority of residents who responded to a Liverpool Council survey about whether they would support an airport at Badgerys Creek were positive about the idea, says preliminary data presented to the council on Monday.
The council gathered residents' views using a telephone survey, focus groups and an online survey, which concluded on November 29.
Cr Tony Hadchiti asked whether there was a way respondents could have completed the online survey several times, but general manager Farooq Portelli said the council had a way of eliminating those submissions.
The council heard that 54 per cent of residents who responded to the telephone survey supported Badgerys Creek as the location of the second airport.
It was also found that 59 per cent of participants of the first focus group and 50 per cent of the people in the second group supported the plan and 52 per cent of responders to the online survey responded positively to it.
