AUSTRALIA'S most adulterous postcodes have been revealed, at least as far as Ashley Madison customers go, as internet users continue to scour data from the cheating site's massive leak.
In Victoria, Melbourne, Melton and Frankston are the hotspots and in NSW it's Barangaroo, Newcastle and Lavender Bay, according to location and credit card data included in the leak.
Orange's 2800 postcode has just shy of 2,000 accounts registered.
And Canberra - capital of our fine nation - ranks right up high.
The analysis comes from data scientists working at Fairfax Media who are analysing the data, and from developer Luke Metcalfe, who works at online property search engine NationMaster.
Fairfax Media's map draws on the locations that users entered when signing up to Ashley Madison.
People can easily insert fake addresses, but there are strong incentives to insert an address close to where you live or work as Ashley Madison goes to some lengths to pair users with other adulterers in their local area.
Mr Metcalfe's maps draw on the postcodes associated with the millions of credit card transactions from around the world made on the Ashley Madison site, which was also included in the leak.
It's not clear whether the postcodes are linked to the place where the card is registered or where the transaction took place.
Mr Metcalfe says he will be updating his property search engine to include the Ashley Madison data, possibly as part of 'suburb hipness' measure the site features.
