The system we use is called the courteous and exchange system. Not first in first serve system or a seniority system like u19 have it over u17s; u17s have it over the u16s etc...
#Rules of engagement - club policy
~If only one team goes to a single ground to train then this team can have the whole ground
If two teams go to a single ground to train then both teams can have a half each
If three teams go to a single ground to train then all three teams will share this ground into thirds
In a case where the middle third team would also like to use the goal mouth or practice corners etc communication between the 3 coaches is done.
They may exchange position during their session so everyone gets a chance to use the goals
I refer this as the courteous and exchange system.
If four teams go to a single ground to share then all four teams must share and the ground is broken up into quarters
If eight miniroos team go to a single ground then this ground is broken up and shared into eights (2 four quarters)
