For Senior Men’s teams, you must have 2 Referees registered for the season to allow for your team to play in the MWFA comp.
This link https://mwfra.org.au/courses/entry/team/ gives you all the info for this process.
Here is the main part of the text….
“As part of the MWFA’s requirements, all senior mens teams AL2s and below have to provide 2 qualified referees. To do this you can undertake a course with the MWFRA. In addition to meeting the MWFA requirements, as a team referee you also get the opportunity to improve the standard of local football, improve your fitness, and get paid. The MWFA pays all the fees associated with becoming a team referee for up to two people per team.”
