Off-market luxury property, before it reaches the market

Most of what Black Diamondz sells is never advertised. Members see it first, on the terms each owner sets.

  • The address

    Never published; shared with the members an owner approves.

  • The price

    Including the $30M+ ultra-luxury listings Prestige members see.

  • The documents

    Released per property, on that property's permissions.

  • A private inspection

    Arranged privately, on the owner's terms.

Members continue with their brief already in the conversation. Start with one of these, or ask your own.

How to apply

  1. Enter your email

    At the top of this page. Members are signed in; everyone else is taken to the application.

  2. We read it

    Every application is read by the Black Diamondz team, rather than scored.

  3. Your card arrives

    Once accepted, add the member card to your wallet and enter the Club.

What is Club Diamondz?

Club Diamondz is the private membership side of Black Diamondz. Members see off-market property that is never publicly advertised, are invited first to the evenings the house runs, and are introduced to the brands and people around it. It is a standing relationship rather than a subscription to a listings feed.

What is an off-market property?

One offered through private introductions rather than a broad public advertising campaign. The owner and agent agree which details may be shared and with whom. It does not necessarily mean a discounted price or an immediate sale.

How do you become a member?

By application or by invitation. There are two tiers: Access, which you apply for, and Prestige, which is by invitation or private review. Start by entering your email on this page; you will be taken to the right form, and every application is read rather than scored.

What is the difference between Access and Prestige?

Access is the membership you apply for: luxury property listings from here and abroad, early previews of select listings and monthly market insights. Prestige is by invitation or private review, and adds priority invitations to events, the most exclusive off-market listings, wealth, legacy and family office concierge, and private introductions to investors and advisors.

Is there a Club Diamondz membership card?

Yes. Every member has a Club Diamondz card, Access in etched black metal and Prestige in etched champagne gold, and adds it to Apple Wallet or Google Wallet from their Club settings. Show it at Club events and with partners for member discounts. It updates itself when your membership changes, so there is nothing to reissue.

What does the Club Diamondz concierge do?

Members ask the Black Diamondz Concierge from inside the Club: what is new on the market this week, a change to the homes they are looking for, a viewing, a question about a suburb. Prestige members also have wealth, legacy and family office concierge.

What is Club Diamondz Market Intelligence?

The Club's own market report, published in issues with a Buyer's Edition and a Seller's Edition. Both carry the same facts; each puts first what matters to its side. It is general market commentary rather than personal advice, and your Black Diamondz advisor can relate any of it to your own position.

Does membership show me every off-market listing?

No, and no honest club would promise it. Membership opens the door; what each owner shows, and when, stays theirs. Addresses, pricing, documents and inspections are released per property, on the permissions that property carries.

Is Club Diamondz only for Sydney houses?

No. Members enquire about residential, commercial, land and rural property, and the house works with buyers and owners in Australia and overseas through its Sydney and Hong Kong offices. Tell us where the property is, or where you are looking. They are often not the same place.

What do members get that the public site does not show?

Four things: off-market listings held back from public advertising, first invitation to the private events, the lifestyle partnerships the house keeps, and introductions inside the member network. The public site shows the listings anyone may see; the Club is the rest of it.

Where do members sign in?

Enter your email at the top of this page, or go straight to club.blackdiamondz.com.au. Either way you are sent a secure link, or asked for the password you set when you joined.
