Caller: Computerised voice that said it was from Amazon

Just received a call from this number; I picked up because I saw it was a Canberra number and thought it might be something relevant to me. A computerised woman's voice said it was from Amazon. I didn't trust it and hung up immediately. I received a similar phone call the other day that had a similar spiel; something about Amazon calling about an iPhone 11 they think I was trying to buy (but was not).
I marked it as a scam call, but I admit it's possible they could be mimicking the number from a legitimate business.

I called back number (02) 6297 1276 spoke to a woman who said company name is St Gregory's Primary.
