Customs fees on imported items. Have they increased? Can someone help me understand?

I ordered some baby clothes from Australia because I wanted a couple of special items from home. The total came to AU $220 including $20 shipping fee, so ~147€. Granted, the items were 20% off because I got them on sale, so the “value” is more like AU $244 (163€ including shipping).

Today I got the customs bill email from DHL for 66.42€ (AU $100)! I was expecting it to be around 19% plus a delivery fee of around 5€ from DHL. It’s double what I anticipated. I had a look at the cost breakdown but it’s pretty meaningless to me.

It lists the following fees:

Zoll (DT): 18.66€; Duty Tax Receiver Service (L1): 14.88€; EuSt (TX): 33.08€

Do I get taxed once for the Eu and once for Germany? Seems extremely high considering the value of the goods.

I also received a gift (some clothes and a small toy for the baby) from my Mum last week (from Australia) which I had to pay 20€ for C.O.D. I don’t understand why it’s suddenly so expensive. Have I missed something. Any info would be much appreciated.
