The NSW GBOTA advises, that based on local advice of rising levels of the WIlson River, the Lismore track has commenced evacuation of the site.
The river is currently predicted to exceed 7m by 9am, March 31, which will see the front of the property cut off.
Trials on March 31 have already been abandoned, with the non-TAB race meeting on April 1 now also abandoned.
The NSW GBOTA hopes all residents in the region remain safe.
Advice with regards to the race meeting on Tuesday, April 4 will be provided closer to the time.
