Interested buyers are being sought to register their interest for the Belair tower as it’s expected to be sold quickly.

Sixty units are on offer in a variety of forms: from one bedroom to three, some with ocean views, others with entertainment terraces and penthouses with high ceilings

The 3.5-hectare site along Pioneer Road comprises three apartment blocks and a 44-home master-planned housing estate.

All but Belair have already been sold.

Belle Property Wollongong agent Darren Kay said he expects a lot of interest from Sydney retirees looking for a sea change.

Mr Kay said the site, between Fairy Meadow and Towradgi, was what many now call the "new North Wollongong".

“People have been waiting for this tower. Once everything’s sold, there’ll also be great capital gains for owners,” Mr Kay said.

No price guide has been given.
