Does anyone know the law regarding interactions with police in Australia?

I have a teenage daughter, she is a typical nerdy red headed girl into reading and such, so unlikely to be profiled for a search, but shit happens.

She also has Autism, and doesn’t do super well with new situations under pressure. Usually we need to talk about what will happen and what we are likely to do beforehand and she’s fine.

Can she refuse to be searched by police? Can she ask to be taken to the station to be searched by a female officer? What happens if she says no to them searching her bag or pockets?
