safe options for teenage dnd?

hi! i moved to canberra a few months ago and have been looking for campaigns mainly made up of teenagers (~year 10-12 ish). i haven’t been able to find anyone in my school with similar interests, and the campaigns i have found are mainly made up of adults, which is weird for a teenage girl to join and i wouldn’t feel super safe lol

i’ve looked into dice 4 diversity & ronin games but d4d seems more like a training session for social interaction (i’m really extroverted already) and ronin needs like. 50 bucks for a sit down session and i’m broke 💔 any advice on how i can find people my age in canberra with similar interests?
