The Block channel—and specifically the latest season coverage—appears to be airing on Channel 9 in Australia, with recent seasons also available to catch up on 9Now. If you’re asking about a particular block or the current live broadcast, the latest updates indicate Channel 9 is the primary broadcaster and 9Now streams are available for online viewing. For the most up-to-date details, check the official The Block pages or the 9Now schedule. If you’d like, I can narrow this down to:

• The current season’s air date and time in your time zone.
• Where to stream the latest episode (9Now vs. Channel 9 broadcast).
• The latest season’s host lineup and prizes.

Please tell me which aspect you want verified or specify your location to tailor the answer.
