According to a Facebook post from Drop.com.au, a drop catching service specializing in .com.au domain names (Australia ccTLD), the Broker.com.au domain name sold for $100,000 (see update below):
Once this sale closes, it will be the largest .com.au sale of the year. It will also tie Deals.com.au and Poker.com.au for the 5th largest publicly reported .com.au sale of all time, according to NameBio. This $100,000 sale will be the second largest publicly reported ccTLD domain name sale of the year, as recorded by DNJournal. The largest ccTLD sale of the year (to date) was the sale of Music.ai, which sold for $101,500 via Undeveloped.
It is unclear who owned Broker.com.au before it dropped. I do not see any entries for Broker.com.au in Archive.org or Screenshots.com.
It will be interesting to see if Broker.com.au was acquired by a domain investor or an end user.
A reader pointed out that the sale was $100,000 AUD rather than USD:
FYI, that is 100,000 AUD.

Assuming that is the case, that would be approximately $73,136.84 USD at the current AUD to USD exchange rate. That would impact quite a bit of what was mentioned above, including where it would rank in terms of all-time .com.au sales and where it would rank on year to date sales.
