ok if you're worried, just wait for the rankings to come out early next year and if Girraween has a 10+ rank difference then apply there ig, but imo their rankings are always gonna be relatively similar and they seem to fluctuate kinda a lot and thats just what happens to schools in rank 30-45. i personally think that you should just apply to penrith bc its sm closer for u and this lowk sounds hypocritical bc of my own situation but travel time can do a LOT, like that 25 minute difference is more sleep or study or just more downtime between school and whatever u need to do afterwards. but you should also consider things like extracurricular culture, overall school culture, etc. (i personally think girra and penrith are very similar in the two aspects)
