A multi-million-dollar new-look Eat Street Markets - with an adventure park geared to national and international tourists - will open in "around five weeks" on a riverside site east of its current home near Hamilton Northside.

The popular market is shifting to let the $400 million Hamilton Northshore development expand along the northern shore of the Brisbane River.

Brisbane's Eat Street Markets will move east of the current site.

Market entrepreneur Peter Hackworth – who opened the Eat Street Markets in 2013 with former actor John Stainton and one of 1970s television's funny ladies, Jacki McDonald – confirmed the shift was on.

"It's what you will call, a big step up," she said.
