LEGO Masters' Ryan McNaught says being a little bit "geeky" and creative has gained more acceptance.

He is the only LEGO certified professional in the southern hemisphere and leads a team responsible for a 7.5 metre rocket and a giant mural of Bendigo imperial dragon Sun Loong, among other works.

"That's my number-one job and I have a team of skilled craftspeople working underneath me. Our normal bread-and-butter is store displays, museums and art galleries," Mr McNaught.

"The TV stuff is sort of the stuff on the side."

There is only one thing he has not enjoyed about the TV show. The eliminations.

The first one in particular made him visibly upset - and not only because he was judging "amazing" and highly skilled people.

"The ethos of LEGO is that you never have to tell anyone they have done a bad job. That was the first time ever in my career I've had to say 'unfortunately your LEGO is not good enough'," Mr McNaught said.

"All the eliminations throughout the show have not been easy."

Mr McNaught got his first LEGO set from his grandmother in 1976. The little blue boat that cost 20 cents from Coles.

"I loved it (playing with LEGO) up until I was about 12 or 13, I guess. Then sport took over," he said.

Mr McNaught's love of the little plastic bricks was forged in the possibilities they held.

"As a child your tastes change. I had a phase where I liked Formula One cars, so I was able to make those. The next month I was into making space ships," he said.

"LEGO bricks can be anything you want them to be."

These days, Mr McNaught liked that LEGO can get children off of devices, and the creativity it can inspire.

The bricks have limitations, but people come up with clever ways to get around them.

"There are 10,000 types of bricks, so the possibilities are infinitely huge. So it should not be a surprise to me but it always is, when people make incredible and amazing things."

The next new episode airs on Sunday night on Channel 9.
