Gallery: The Block open for inspection

Around 20,000 people turned up to The Block Open for Inspections in South Yarra over the weekend.

All the Triple Threat contestants were there to meet fans, along with Scott Cam, Shelley Craft, Shaynna Blaze, Darren Palmer, Keith Schleiger and Dan Reilly.

Once again there were plenty of families and kids out in force hunting for autographs, selfies and having a gander at the finished renovations.

Auctions will take place on Tuesday April 28, with the finale tipped for the following night.
