Wet weather across the Great Lakes in the past fortnight has forced the cancellation of two sport events on Saturday, February 27.
Tuncurry's Harry Elliot Oval was set to host four representative rugby league matches featuring the North Coast Bulldogs under 16s, under 18s open women and open men's sides.
These matches will now be played on March 13-14.
The Men of League Race Day at Forster Tuncurry Jockey Club will be moved to Muswellbrook.
The decision was made following a track inspection by Racing NSW stewards earlier this week. The track was deemed unsuitable to race due to significant rainfall.
Despite some warm weather in the past few days, the track is still not safe for racing.
All nominations and acceptances were maintained for the race day but three of the six race lengths have been altered.
The Men of League activities will be shifted to Tuncurry Beach Bowling Club, starting from noon.
