The top postcode for first-home buyers in the past three months is 2560.
"This postcode includes the hubs of Campbelltown, Leumeah, Macarthur Square and Appin, which are strong communities in themselves, and have the added advantage of being within commutable distance to the Sydney CBD," Bailie said.
"It's positive to see younger buyers entering the property market, with 69 per cent of those who purchased in the 2560 postcode last quarter aged under 39.
"A closer analysis shows more than a third were aged 30-39, followed closely by 20–29-year-olds who made up 32 per cent of the buying cohort."
Bailie said properties ranging from $700- $800,000 were the most popular.
