Thirroul's $3.8M "Bluechip" Has Been Sitting For 442 Days. The 29-Day Average Never Mentions It. Week Ending 20 September 2026

Every Sydney buyer I talk to starts from the same place: everything down here moves fast now. Fair call, on paper. The region's median days on market sits at 29, down from 36 a year ago, and Helensburgh is still clearing houses in about a fortnight.

What nobody mentions is what's sitting underneath that number. There's a $3.8 million "Bluechip" listing on Bath Street in Thirroul that's been live since before last Christmas: 442 days and counting.

Up on Mangerton Road, on the leafy fringe of the Wollongong CBD, a light-filled auction listing has been sitting for 492 days. Neither one is hidden. Both are on the portals right now, sandwiched between houses that sold inside three weeks.

That's not bad luck, it's what happens when a vendor prices for a market that peaked earlier this year and won't move as conditions soften under them. The Illawarra has now posted four straight months of falling dwelling values, the sharpest monthly drop since January 2023.

A brisk median doesn't mean a brisk market at every price point, it means the cheap and mid-tier stock is selling fast enough to drag the average down while the top end sits and quietly rots.

Agents around here will tell you privately what the portals won't show you in one number: there's a growing pile of listings past the 12-month mark that never make it into the headline days on market figure, because the moment a listing gets pulled and relaunched, the clock resets and the history disappears.

Buyers scrolling Domain see a fresh listing with zero days on market. They don't see that it's the same house, third agent, fourth price guide, fourteen months in.

If you're circling anything north of $2 million in this corridor, you're not negotiating against a 29-day market. You're negotiating against a vendor who's watched 400-plus days of silence and is only just starting to accept that the number in their head from March isn't the number September will pay.

That gap between what a listing first asks and what it eventually settles for is where the real conversation happens, and it's wider right now than at any point this year.

THE NUMBERS

• NSW clearance rate: 54.0% (week to 19 Sept), down from 78.0% the same week last year

• Illawarra dwelling values: down 1.1% in August, the fourth straight monthly fall

• Two corridor listings sitting 442 and 492 days against a 29-day regional median

THE ONE ACTION

Before you ask an agent for the price guide on anything over $2 million in the corridor, ask how long it's actually been listed. Past 90 days at that price point for the past 90 days, you're dealing with a vendor who's already lost the negotiation;; they just don't know it yet. Open 15 to 20 per cent under the guide and let the silence do the rest of the work.
