The show is bigger and grander than ever. Joining Hamish Blake and Ryan 'Brickman' McNaught are 16 returning contestants, all competing for the ultimate title of Australia's Grand Masters.

Each of the eight teams must create a build which tells a story both as it goes over the edge of a waterfall, and as it crashes on the rocks below.

It's the third and final challenge of Brick Week, where the winning team will take home the Grand Brick, granting them immunity from the first elimination.

The first elimination challenge sees the contestants complete a two-part theme park challenge.

All seven teams must create a well-known or original secret, mystery, or conspiracy theory out of LEGO.

The seven remaining teams face the hardest competition in LEGO Masters history, as they send their LEGO models to 'space' to win an advantage for the second part of the challenge and avoid elimination.

The six remaining teams must create an iconic scene from a Disney movie.

It's boom time for the Grand Masters with this challenge setting them to create a scene to be exploded for the camera.

The six remaining Grand Master teams are challenged with building their own portion of a city-wide Heist, taking place in mini figure scale.

The best challenges from the last four seasons have been selected and the remaining Grand Masters teams must each build a different challenge, competing against the winning builds from that original challenge.

Teams face their own individual sheer cliff face wall made with LEGO. Their challenge is to create a vertical build that brings their cliff face base plate to life while pushing LEGO to the limits!

In the penultimate challenge of LEGO Grand Masters, each team will build one 'Jumper' that is part of a larger carousel. Final builds will be revealed on a fully functional carousel under the lights of Sydney's Luna Park.

In the epic LEGO Grand Masters finale, the last three teams standing will create an amazing build of their choosing. 200 members of the public, along with Brickman, will determine the ultimate winners of 'Grand Masters' 2023.
