A highlight of the meeting will be a report by WBRFU chief executive officer Tony Hargood that will likely include recommendations which, if accepted, would see radical changes made to the competition format next season.
"He (Hargood) thinks outside the square and it's going to be really interesting to see what he comes up with," Nathan said.
"We can't keep going with what we've got; it's just not working."
Part of Wednesday's discussions is also likely to centre on the unusually high number of defaults in premier division play this season with special emphasis being placed on what should occur when the defaulting team fields a senior thirds side on the same day.
