Hi Bee. My DD has been offered a place in 2 schools too. 1 for profit and 1 not for profit (also offering debentures and the like... so I guess it would be the same school you are referring to).
I have an older DS that is entering year 7 next year and we tried 2 profit making schools with him. TO be honest, it is not totally true that profit making schools invest more into the facilities. Both schools he was in are reputable schools but they do tend to have large sized classes in order to get the most money for as little cost as possible. The school sizes are huge with many classes for each year group and the facilities, despite being great, are not enough for the number of students in the school. So for example, the canteen fits 100 kids... but each year group has 200 kids... so they end up allocating different days for each year group to be allowed to go to the canteen, and different hours during that day for the different classes in that year group.
My DS's class is allocated a Sunday 12 noon slot. So they are not allowed to go any other day or time. I don't think this makes sense.
Same goes for the playground that does not fit all the primary kids... so they have different play times for the different year groups.
I have definitely decided to place my DD in the non-profit school and pay a personal debenture. My DS will also move to the same school (we were lucky that when DD got a place, DS was given sibling priority and got offered a place too).
Hope this helps you a bit more in making an informed decision.
