That means anything within a (co-moving) distance of 3.3 Gpc, 11 Gly or 100 000 000 000 000 000 000 000 km.
The "local Universe" also includes most of Time. At a redshift of 1 you're looking 7.7 Gyr back in time, about 5.8 Gyr after the Big Bang.

Mild amusement at the Australian astronomy Decadal Plan town hall that the extra-galactic astronomers and cosmologists now consider anything below a redshift of 1 to be "local".
That means anything within a (co-moving) distance of 3.3 Gpc, 11 Gly or 100 000 000 000 000 000 000 000 km.
