Best two zone Amplifier with network streamer

Looking for advice on an amp that can handle a pair of bookshelf speakers for inside my house as zone 1, and a 2nd pair of outdoor speakers as zone 2. I want to be able to control them independently, e.g. watch TV or play music inside only on the bookshelf speakers, or play music exclusively outside. I mainly use Google Assistant/Chromecast for my music.

I've looked at the Wiim amp and other budget options but I think these can only handle one set of speakers. My bookshelf speakers at q3030i and some fairly basic polk atrium speakers for outside. The amps I've seen are much more expensive than my speakers and I'm not sure if this is the best budget split, e.g. should I be spending more on the speaker and less on the amp.

Would love some advice. I'm in Australia if that helps for product recommendations.
